It is important for people's eyes to remain moist. Describe how your eyes felt after not blinking. Do you think blinking is helpful and protective? Explain.

Answers

Yes blinking is helpful, it helps keep the eyes clean and protect them. By blinking you are sweeping away small particles that could be harmful to the eye. Everytime we blink a small quantity of tear comes out wetting the lower third of the cornea

Blinking is essential for keeping the eyes moist and clear of debris, using the lacrimal apparatus to spread tears across the eye's surface, which highlights the importance of blinking for eye protection and comfort.

Blinking is a protective reflex that is crucial for maintaining eye health by keeping the eyes moist and free from debris. When we do not blink, our eyes can start to feel dry and uncomfortable due to the lack of moisture; a condition known as dry eye can occur. The discomfort experienced from not blinking is evidence of the protective role blinking plays.

It is through this reflex that the lacrimal apparatus, comprising the lacrimal gland, lacrimal canaliculi, lacrimal sac, and nasolacrimal duct, produces lacrimal fluid (tears) which hydrates and cleanses the eyes.

The palpebral conjunctiva, the thin membrane lining the eyelids, extends over the sclera (the white of the eye), aiding in the process of distributing the tears across the eye surface. Therefore, blinking is not just helpful but essential for preserving good vision and protecting the eyes from potential irritants and infections.

View Available Hint(s) tert-Butyl alcohol is a solvent with a of 9.10 and a freezing point of 25.5 . When 0.807 of an unknown colorless nonelectrolyte liquid was dissolved in 11.6 of tert-butyl alcohol, the solution froze at 15.3 .Which of the following is most likely the identity of this unknown liquid? ethylene glycol (molar mass = 62.07 g/mol) 1-octanol (molar mass = 130.22 g/mol) glycerol (molar mass = 92.09 g/mol) 2-pentanone (molar mass = 86.13 g/mol) 1-butanol (molar mass = 74.12 g/mol)

Answers

Answer:

ethylene glycol (molar mass = 62.07 g/mol).

Explanation:

We can solve this problem using the relation:

ΔTf = Kf.m,

ΔTf is the depression in the freezing point of tert-Butyl alcohol (ΔTf = freezing point of pure solvent - freezing point in presence of unknown liquid = 25.5°C - 15.3°C = 10.2°C).

Kf is the molal freezing point constant of tert-Butyl alcohol (Kf = 9.1 °C/m).

m is the molality of unknown liquid.

∵ ΔTf = Kf.m

∴ m = ΔTf/Kf = (10.2°C)/(9.1 °C/m) = 1.121 m.

We need to calculate the molar mass of the unknown liquid:

Molality (m) is the no. of moles of solute in 1.0 kg of solvent.

∴ m = (mass/molar mass) of unknown liquid/(mass of tert-Butyl alcohol (kg))

m = 1.121 m, mass of unknown liquid = 0.807 g, mass of tert-Butyl alcohol = 11.6 g = 0.0116 kg.

∴ molar mass of unknown liquid = (mass of unknown liquid)/(m)(mass of tert-Butyl alcohol (kg)) = (0.807 g)/(1.121 m)(0.0116 kg) = 62.06 g/mol.

So, the unknown liquid is:

ethylene glycol (molar mass = 62.07 g/mol).

If 89.6 joules of heat 20.0 grams of iron from 30.0 C to 40.0 C, what is the specific heat of the iron in J/g.C?

Answers

Answer:

 

H = m c ΔT  

89.6 J = (20.0 g) × c × (40.0 - 30.0)°C  

Specific heat of iron, c = 89.6 / [20.0 × (40.0 - 30.0)] J/(g°C) = 0.448 J/(g°C)

If 89.6 joules of heat 20.0 grams of iron from 30.0 C to 40.0 C, then the specific heat of the iron in J/g. degree C is 0.448 J/g. degree C.

How do we calculate the specific heat?

The formula which we used to calculate the amount of specific heat of any substance involved in a chemical reaction is:

Q = mcΔT, where

Q = absorbed heat = 89.6 Jm = mass = 20gc = specific heat = ?ΔT = change in temperature = 40 - 30 = 10 degree C

On putting all these values, we get

c = 89.6 / (20)(10) = 0.448 J/g. degree C

Hence, 0.448 J/g. degree C is the specific heat of iron.

What is added to white sugar to create brown sugar?

Answers

Molasses is the answer

Brown sugar is made by adding molasses to refined white sugar, which may have been processed using bone char. The addition of molasses gives the distinct color and flavor to brown sugar.

Brown sugar is created by adding molasses to refined white sugar. This addition not only gives brown sugar its distinct color, but also imparts a rich flavor and increases the moisture content compared to white sugar. In the production process of brown sugar, it is important to note that if the white sugar utilized has been refined using bone char as a decolorizing filter, then the same process would likely be used in the production of the brown sugar from that manufacturer.

Bone char is derived from animal bones, and even though it is widely used in the sugar industry to achieve the white color of sugar, some consumers may seek alternatives due to dietary preferences or ethical concerns.

Sugar comes in various forms including beet sugar, cane sugar, and specialty sugars like coconut sugar or maple sugar. As for icing or powdered sugar, often used in icings and baked goods, it consists of refined sugar mixed with cornstarch and might also involve the use of bone char in its production.

The human eye is able to detect as little as 2.35 × 10–18 j of green light of wavelength 510 nm. Calculate the minimum number of photons of green light that can be detected by the human eye. Physical constants can be found here.

Answers

The minimum number of photons of green light, with 2.35x10⁻¹⁸ J of energy and 510 nm of wavelength, that can be detected by the human eye is 6.04 photons.    

The energy of a single photon is given by:

[tex] E_{1} = h\frac{c}{\lambda} [/tex]

Where:  

h: is the Planck constant = 6.62x10⁻³⁴ J*s

λ: is the wavelength of the green light = 510 nm = 510x10⁻⁹ m

c: is the speed of light = 3.00x10⁸ m/s

So, the energy of one photon is:    

[tex]E_{1} = h\frac{c}{\lambda} = 6.62 \cdot 10^{-34} Js\frac{3.00 \cdot 10^{8} m/s}{510 \cdot 10^{-9} m} = 3.89 \cdot 10^{-19} J[/tex]  

Now, since the energy of the green light detected by the human eye is 2.35x10⁻¹⁸ J, the minimum number of photons (n) to produce that amount of energy is:  

[tex] E_{n} = nE_{1} [/tex]

[tex] n = \frac{E_{n}}{E_{1}} = \frac{2.35 \cdot 10^{-18} J}{3.89 \cdot 10^{-19} J} = 6.04 [/tex]  

Therefore, the minimum number of photons of green light is 6.04 photons.

4. For 0.2 [tex]NaCl[/tex]

[tex]NaCl\rightarrow Na^{+}+Cl^{-}[/tex]  

, i= 2 as it is a electrolyte and dissociate to give 2 ions, concentration of ions will be [tex]1\times 0.2+1\times 0.2=0.4[/tex]

Thus as concentration of solute is highest for [tex]Al_2(SO_4)_3[/tex] , the vapor pressure will be lowest.

Alkali metals react with water to produces what product?

Answers

Answer:

Alkali metals react with water to produce hydroxide and hydrogen gas.

Explanation:

That is a chemical property of alkali metals: they are highly reactive and react vigorously with water to produce the correspondant hydroxide and hydrogen gas.

These are some of those reactions:

2Li (s) + 2H₂O (l)  → 2LiOH (aq) + H₂(g) ↑

2Na (s) + 2H₂O (l)  → 2NaOH (aq) + H₂(g) ↑

2K (s) + 2H₂O (l)  → 2KOH (aq) + H₂(g) ↑

The alkali metals are the elements of group 1 of the periodic table: Li, Na, K, Rb, Cs, and Fr. They have one valence electron which may lose easily to form an ion with charge +1.

Final answer:

Alkali metals react with water to produce hydrogen gas and a basic solution of the metal hydroxide (for instance, sodium hydroxide when lithium is in the reaction). This reaction signifies the easier oxidation of alkali metals compared to hydrogen.

Explanation:

When alkali metals react with water, they form hydrogen gas and a basic solution of the metal hydroxide. This vigorous reaction reveals that alkali metals are easier to oxidize than is hydrogen. For instance, considering the reaction of lithium with water:

2Li(s) + 2H₂O(l) --> 2NaOH(aq) + H₂(g)

The solid state (s) lithium reacts with liquid water to generate hydrogen gas and the ionic compound sodium hydroxide. This sodium hydroxide, which is a solid in its pure form, promptly dissolves in water.

The same kind of reaction occurs with other alkali metals and also some alkaline earth metals, although beryllium and magnesium are exceptions.

Thanks and have a awesome day!

The main characteristic of a strong acid or base is that it completely ionizes in water. Option A is correct.

This means that the acid or base will dissociate into its ions when it is dissolved in water. For example, hydrochloric acid (HCl) is a strong acid that completely ionizes in water to form hydrogen ions (H⁺) and chloride ions (Cl⁻).

HCl(aq) → H⁺(aq) + Cl⁻(aq)

The presence of a hydroxide or hydrogen ion is also a characteristic of strong acids and bases, but it is not the only characteristic. For example, ammonia (NH₃) is a base that does not have a hydroxide ion, but it does dissociate into ammonium ions (NH₄⁺) and hydroxide ions (OH⁻) when it is dissolved in water.

NH₃(aq) + H₂O(l) → NH₄⁺(aq) + OH⁻(aq)

Polar covalent bonding is not a characteristic of strong acids or bases. Polar covalent bonding is a type of bonding that occurs between two atoms that have different electronegativities. The more electronegative atom will have a partial negative charge, while the less electronegative atom will have a partial positive charge. Option A is correct.

Na2O How many atoms of each element are in this compound? A. 2 sodium atoms and 1 oxygen atom B. 2 sodium atoms and 2 oxygen atoms C.1 sodium atoms and 1 oxygen atoms D.1 sodium atom and 2 oxygen atoms

Answers

Answer:

A

Explanation:

There are 2 sodium atoms and 1 oxygen atom.

In Na2O, there are 2 sodium atoms and 1 oxygen atom, as indicated by the chemical formula, which represents a 2:1 ratio of sodium to oxygen with an overall neutral charge.

The compound Na2O consists of two elements: sodium (Na) and oxygen (O). According to the chemical formula, for every one unit of this compound, there are two sodium atoms and one oxygen atom. This is because the subscript '2' next to Na in the formula indicates there are two sodium atoms, while the absence of a number next to O implies there is one oxygen atom. Hence, in the compound Na2O, the ratio of sodium to oxygen atoms is 2:1, which is due to the need for the number of electrons lost by sodium (each Na atom loses one electron) to equal the number of electrons gained by oxygen (the O atom gains two electrons) and ensure the compound has an overall neutral charge. Therefore, the correct answer is A: 2 sodium atoms and 1 oxygen atom.

What characteristics do solid ionic compounds share?

Explanation:

Just a brief introduction to remember what the ionic compounds are. Ionic compounds are the compounds formed by ionic bonds, i.e. the eletrostatic attraction between cations (positivie ions) and anions (negative ions). The ionic compounds are mostly either oxides or salts. An example of an ionic oxide is CaO, and an example of an ionic salt is NaCl.

The strength of the ionic bonds is responsible for most of the characteristics of these compounds. These are the most common characteristics that solid ionic compounds share:

They form cristals: the ionic compounds form long networks of atoms very organized, instead of individual units. That is why you must not refer to these compounds as molecules.

HIgh boiling and melting points: because high energy is required to separate the ions, and form the new state.

Bad conductors of electricity: since the ions are in fixed position, they do not carry charges (the charges are not moving), so in solid state, the ionic compounds are bad conductors (but in aqueous solution they are very good conductors).

Hardness: crystals are relatively hard and when they are hammered they brake apart.

Approximately how many atoms of carbon are present in a 120 gram sample of carbon?

Answers

Final answer:

A 120-gram sample of carbon contains approximately 6.02 x 10^24 atoms. We calculate this based on the fact that a mole of carbon weighs 12 grams and contains 6.02 x 10^23 atoms.

Explanation:

The subject you're studying is related to atoms, more specifically, counting the number of carbon atoms in a given mass. To solve this, we need to understand the concept of a mole. A mole is an amount of substance that contains the same number of entities (atoms in this case) as there are in exactly 12 grams of ¹2C, or carbon-12. Hence, one mole of carbon is equivalent to 12 grams of carbon, and this mole contains 6.02 x 10^23 atoms (this number is called Avogadro's Number).

Given that your sample is 120 grams of carbon, this translates to 10 moles of carbon since 120 grams divided by 12 grams/mole equals 10 moles. So, the number of carbon atoms present in your 120 grams sample would be 10 moles multiplied by Avogadro's number, equating to approximately 6.02 x 10^24 carbon atoms.

Read the passage.Abraham LincolnSecond Inaugural AddressMarch 4, 1865President Lincoln gave his second inaugural address in March 1865. The Civil War had been raging for years, and hundreds of thousands of Americans were dead. The war was nearly over, but President Lincoln would not see the country reunited. He was assassinated in April 1865.Fellow-Countrymen:At this second appearing to take the oath of the Presidential office there is less occasion for an extended address than there was at the first. Then a statement somewhat in detail of a course to be pursued seemed fitting and proper. Now, at the expiration of four years, during which public declarations have been constantly called forth on every point and phase of the great contest which still absorbs the attention and engrosses the energies of the nation, little that is new could be presented. The progress of our arms, upon which all else chiefly depends, is as well known to the public as to myself, and it is, I trust, reasonably satisfactory and encouraging to all. With high hope for the future, no prediction in regard to it is ventured.On the occasion corresponding to this four years ago all thoughts were anxiously directed to an impending civil war. All dreaded it, all sought to avert it. While the inaugural address was being delivered from this place, devoted altogether to saving the Union without war, insurgent agents were in the city seeking to destroy it without warseeking to dissolve the Union and divide effects by negotiation. Both parties deprecated war, but one of them would make war rather than let the nation survive, and the other would accept war rather than let it perish, and the war came.One-eighth of the whole population were colored slaves, not distributed generally over the Union, but localized in the southern part of it. These slaves constituted a peculiar and powerful interest. All knew that this interest was somehow the cause of the war. To strengthen, perpetuate, and extend this interest was the object for which the insurgents would rend the Union even by war, while the Government claimed no right to do more than to restrict the territorial enlargement of it. Neither party expected for the war the magnitude or the duration which it has already attained. Neither anticipated that the cause of the conflict might cease with or even before the conflict itself should cease. Each looked for an easier triumph, and a result less fundamental and astounding. Both read the same Bible and pray to the same God, and each invokes His aid against the other. It may seem strange that any men should dare to ask a just God's assistance in wringing their bread from the sweat of other men's faces, but let us judge not, that we be not judged. The prayers of both could not be answered. That of neither has been answered fully. The Almighty has His own purposes. "Woe unto the world because of offenses; for it must needs be that offenses come, but woe to that man by whom the offense cometh." If we shall suppose that American slavery is one of those offenses which, in the providence of God, must needs come, but which, having continued through His appointed time, He now wills to remove, and that He gives to both North and South this terrible war as the woe due to those by whom the offense came, shall we discern therein any departure from those divine attributes which the believers in a living God always ascribe to Him? Fondly do we hope, fervently do we pray, that this mighty scourge of war may speedily pass away. Yet, if God wills that it continue until all the wealth piled by the bondsman's two hundred and fifty years of unrequited toil shall be sunk, and until every drop of blood drawn with the lash shall be paid by another drawn with the sword, as was said three thousand years ago, so still it must be said "the judgments of the Lord are true and righteous altogether."With malice toward none, with charity for all, with firmness in the right as God gives us to see the right, let us strive on to finish the work we are in, to bind up the nation's wounds, to care for him who shall have borne the battle and for his widow and his orphan, to do all which may achieve and cherish a just and lasting peace among ourselves and with all nations.Question 1Part AHow does Lincolns use of the words offenses, woe, and scourge affect Paragraph 3?They create a righteous and superior tone.They shift the tone from one of anger to one of pity.They reinforce the speech's aggressive and unforgiving tone.They convey a condemnatory and judgmental tone.Question 2Part BHow do the tone identified in Part A and the allusion Lincoln uses in Paragraph 3 advance his purpose?Both convey the idea that suffering is a consequence of injustice. Both identify the dwindling strength of the country. Both suggest the need for persistence in the fight for a worthy cause.Both work to elevate the belief that all people are equal.
