First we have to refer
to the reaction between the acid and the base:
H2SO4 + 2 NaHCO3 ---> 2 H2O + 2 CO2 + Na2SO4
From this balanced equation we can see that for every 1 mol
of acid (H2SO4), we need 2 mol of base (NaHCO3) to neutralize it. Given 28 ml
of 5.8 M acid, we need to find out how many mols of acid that is:
28mL * (1L/1000mL) * 5.8 mol/L = 0.1624 mol H2SO4
Since we need 2 mol of base per mol of acid, we need:
2*0.1624 mol = 0.3248 mol NaHCO3
MolarMass of NaHCO3 is 84.01 g/mol
0.3248 mol*(84.01g/mol) = 27.29 g NaHCO3
Answer: The mass of sodium hydrogen carbonate that must be added is 27.28 g
Explanation:
To calculate the number of moles for given molarity, we use the equation:
[tex]\text{Molarity of the solution}=\frac{\text{Moles of solute}\times 1000}{\text{Volume of solution (in mL)}}[/tex]
Molarity of sulfuric acid solution = 5.8 M
Volume of solution = 28 mL
Putting values in above equation, we get:
[tex]5.8M=\frac{\text{Moles of sulfuric acid}\times 1000}{28mL}\\\\\text{Moles of sulfuric acid}=0.1624mol[/tex]
The chemical equation for the reaction of sulfuric acid and sodium hydrogen carbonate follows:
[tex]H_2SO_4(aq.)+2NaHCO_3(aq.)\rightarrow Na_2SO_4(aq.)+2CO_2(g)+H_2O(l)[/tex]
By Stoichiometry of the reaction:
1 mole of sulfuric acid reacts with 2 moles of sodium hydrogen carbonate.
So, 0.1624 moles of sulfuric acid will react with = [tex]\frac{2}{1}\times 0.1624=0.3248mol[/tex] of sodium hydrogen carbonate
To calculate the number of moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}[/tex]
Molar mass of sodium hydrogen carbonate = 84 g/mol
Moles of sodium hydrogen carbonate = 0.3248 moles
Putting values in above equation, we get:
[tex]0.3248mol=\frac{\text{Mass of sodium hydrogen carbonate}}{84g/mol}\\\\\text{Mass of sodium hydrogen carbonate}=(0.3248mol\times 84g/mol)=27.28g[/tex]
Hence, the mass of sodium hydrogen carbonate that must be added is 27.28 g
A fatty acid which contains only single covalent bonds between its carbon atoms is unsaturated.
Saturated fatty acids are those with single bonds between carbons, maximized with hydrogen atoms. Unsaturated fatty acids contain one or more double bonds. The type of bond influences the fatty acid's properties.
Explanation:The statement in your question seems to have a misunderstanding. A fatty acid that contains only single covalent bonds between its carbon atoms is actually a saturated fatty acid, not unsaturated. This is because in a fatty acid chain, if there are only single bonds between neighboring carbons in the hydrocarbon chain, it is said to be saturated. Saturated fatty acids, such as stearic acid, are in simplest terms, saturated with hydrogen. This simply means the number of hydrogen atoms attached to the carbon skeleton is maximized.
On the other hand, fatty acids that have one or more double bonds between carbons in the chain are classified as unsaturated fatty acids. Examples include monounsaturated fats, which have one double bond in the molecule (like in olive oil), and polyunsaturated fats, which have more than one double bond in the molecule (such as in canola oil). An example of an unsaturated fatty acid is oleic acid.
Remember that the nature of bonds (single or double) in a fatty acid affects its properties, such as its state at room temperature. Saturated fatty acids generally are solid or semi-solid at room temperature, while unsaturated fatty acids usually are liquid.

The atomic nucleus does not contain ____________, which are negatively charged subatomic particles.
The atomic nucleus does not contain electrons, which are the negatively charged subatomic particles that orbit the nucleus. Protons and neutrons, carrying positive and no charge respectively, are the ones that make up the nucleus.
The atomic nucleus does not contain electrons, which are negatively charged subatomic particles. The nucleus is a positively charged region consisting of protons, which have a positive electric charge, and neutrons, which are neutral. Electrons are instead located outside the nucleus, moving through the mostly empty space that makes up the rest of the atom. These subatomic particles—protons, neutrons, and electrons—are bound by forces that define the structure of the atom. The arrangement of these particles explains why the nucleus itself carries a net positive charge, balanced by the negative charge of the electrons that orbit around it.

Redox reaction:
It is a type of chemical reaction in which the oxidation states of atoms are changed. In this reaction, both reduction and oxidation are carried out at the same time. Such reactions are characterized by the transfer of electrons between the species involved in the reaction.
The process of gain of electrons or the decrease in the oxidation state of the atom is called reduction while that of loss of electrons or the increase in the oxidation number is known as oxidation. In redox reactions, one species lose electrons and the other species gain electrons. The species that lose electrons and itself gets oxidized is called as a reductant or reducing agent. The species that gains electrons and gets reduced is known as an oxidant or oxidizing agent. The presence of a redox pair or redox couple is a must for the redox reaction.
The general representation of a redox reaction is,
[tex]{\text{X}}+{\text{Y}}\to{{\text{X}}^+}+{{\text{Y}}^-}[/tex]
The oxidation half-reaction can be written as:
[tex]{\text{X}}\to{{\text{X}}^+}+{e^-}[/tex]
The reduction half-reaction can be written as:
[tex]{\text{Y}}+{e^-}\to{{\text{Y}}^-}[/tex]
Here, X is getting oxidized and its oxidation state changes from [tex]0[/tex]to +1 whereas B is getting reduced and its oxidation state changes from 0 to -1. Hence, X acts as the reducing agent whereas Y is an oxidizing agent.
Rules to calculate the oxidation states of elements:
1. The oxidation number of a free element is always zero.
2. The oxidation number of oxygen is generally taken as -2, except for peroxides.
3. The oxidation state of hydrogen is normally taken as +1.
4. The sum of oxidation numbers of all the elements present in a neutral compound is zero.
5. The oxidation numbers of group 1 and group 2 elements are +1 and +2 respectively.
The oxidation state of O is -2 and the oxidation state of Li is +1.
The expression to calculate the oxidation state in [tex]{\text{LiN}}{{\text{O}}_3}[/tex]is:
[tex]\left[ {1\left( {{\text{oxidation state of Li}}} \right) + 1\left( {{\text{oxidation state of N}}} \right) + 3\left( {{\text{oxidation state of O}}} \right)} \right] = 0[/tex] …… (1)
Rearrange equation (1) for the oxidation state of N.
[tex]{\text{Oxidation state of N}} = \left[ { - 1\left( {{\text{oxidation state of Li}}} \right) - 3\left( {{\text{oxidation state of O}}} \right)} \right][/tex] …… (2)
Substitute -2 for the oxidation [tex]{\text{state}}[/tex] of O and +1 for the oxidation state of Li in equation (2).

An open end mercury manometer was constructed from a u-shaped tube. in a particular measurement, the level in the end connected to the gas manifold, on which the experiment was being conducted, measured 76.2 cm above the u-neck, while the level in the open end (to the atmosphere) was 23.8 cm above the u-neck. the outside air pressure in the laboratory was measured as 754 torr. what is the pressure in the gas manifold?
The pressure in the gas manifold can be computed by adding the atmospheric pressure (754 torr) to the pressure difference in the manometer (52.4 torr), yielding an absolute pressure of 806.4 torr.
Explanation:The question pertains to the use of an open-end mercury manometer, a tool used to measure the pressure of a gas. The difference in height between the mercury levels on the gas side and the open side of the tube represents the pressure of the gas relative to atmospheric pressure.
In your case, the gas side is 76.2 cm above the U-neck, while the open side is 23.8 cm above. The pressure difference (Δh) is therefore 76.2 cm - 23.8 cm = 52.4 cm. Remembering that 1 torr is approximately equal to 1 cm of mercury, the pressure of the gas is therefore 52.4 torr above atmospheric pressure.
However, because the atmospheric pressure in the lab is 754 torr, we must add this to our pressure difference to get the absolute pressure of the gas in the manifold. So, the pressure in the gas manifold is 52.4 torr + 754 torr = 806.4 torr.

The pressure in the gas manifold is found by determining the height difference between the mercury levels in the manometer, which is then added to the atmospheric pressure. The result, 806.4 torr, is the pressure within the gas manifold.
Explanation:The subject of your question relates to the area of physics, specifically fluid dynamics and pressure. In the scenario described, we are dealing with an open-end mercury manometer, which serves as a pressure measurement tool. The pressure in the gas manifold can be determined using the measurements provided and the principles of pressure in manometers.
Firstly, let's find the height difference between the mercury levels. Subtract the level in the open end from the level on the gas manifold side (76.2 cm - 23.8 cm = 52.4 cm). Given that the air pressure is provided in torr, we need to keep consistent units, so 1 cm of Hg equals 13.6 mm of water, which equates to about 1 torr of pressure. Therefore, our height difference is 52.4 torr.
Finally, to find the pressure in the gas manifold, add the atmospheric pressure to the difference in pressure measured by the manometer (754 torr + 52.4 torr = 806.4 torr). Thus, the pressure in the gas manifold is 806.4 torr.

is frying an egg a physical or chemical change
Frying an egg is a chemical change because the heat causes the proteins in the egg to chemically react and change structure, resulting in a solid form with altered color and texture that cannot be reversed.
Explanation:Frying an egg is an example of a chemical change. When an egg is fried, the proteins in the egg white and yolk undergo a chemical reaction caused by the heat. This reaction changes the proteins' structure, making the egg change from a liquid to a solid. The chemical change is evident by the egg's altered color, texture, and inability to return to its original state. Similar to how burning gasoline in a vehicle's engine is a chemical change that powers the vehicle, the cooking of an egg involves altering the chemical structure of its components.
Magnesium has an atomic mass of 24.3. there are two isotopes of magnesium - one contains 12 neutrons and the other contains 13 neutrons in the nucleus. what is the fractional abundance of the one that contains 12 neutrons?
The fractional abundance of the magnesium isotope with 12 neutrons, Mg-24, is 78.70%.
Explanation:The question revolves around calculating the fractional abundance of magnesium isotopes. The given atomic mass is a weighted average of the isotopes based on their natural abundance. Since magnesium has isotopes with mass numbers of 24, 25, and 26, you would use the following equation to find the fractional abundance of Mg-24 (which has 12 neutrons):
Atomic mass = (Fractional abundance of Mg-24 x Mass of Mg-24) + (Fractional abundance of Mg-25 x Mass of Mg-25) + (Fractional abundance of Mg-26 x Mass of Mg-26)
Since the question seeks the fractional abundance of the isotope with 12 neutrons (Mg-24), and we are given that Mg-24 comprises 78.70% of magnesium atoms, it means that the fractional abundance of Mg-24 is 0.787 or 78.70%.

When sugar is mixed with water, equilibrium is reached when __________?
When sugar is mixed with water, equilibrium is reached when the rate of sugar dissolving in water equals the rate of sugar crystallizing or precipitating out of the solution.
This dynamic state of equilibrium is governed by the principles of solubility and saturation. Initially, when sugar is added to water, it dissolves as sugar molecules break apart and become surrounded by water molecules, forming a solution. As more sugar is added, the concentration of sugar in the solution increases until it reaches a point where no more sugar can be dissolved; this is called the saturation point.
At this stage, the rate of dissolution equals the rate of crystallization, resulting in a stable equilibrium where the concentration of dissolved sugar remains constant. The temperature and other factors can influence the equilibrium point, as changes in these conditions may shift the balance between dissolution and crystallization.

How many oxygen atoms are present in 23.6 grams of aspartame?
There are approximately 2.41 x 1024 oxygen atoms in 23.6 grams of aspartame. The calculation involves determining the molecular mass of aspartame, finding the number of moles in 23.6 grams and multiplying it by the number of oxygen atoms per molecule and Avogadro's number.
Explanation:To determine the number of oxygen atoms in 23.6 grams of aspartame, we first need to find the molecular mass of aspartame (C14H18N2O5). This is done by adding up the atomic masses of the constituent atoms, which equals to 294.31 g/mol. Next, we use Avogadro's number, which states that one mole of any substance contains 6.02 x 1023 molecules.
Therefore, the number of moles of aspartame in 23.6 grams is 23.6/294.31, which equals to approximately 0.080 moles. Because each molecule of aspartame contains 5 oxygen atoms, we multiply the number of moles by 5 to get the number of moles of oxygen in 23.6 grams of aspartame. Then, we multiply this by Avogadro's number to obtain the number of oxygen atoms. Hence, there are approximately 2.41 x 1024 oxygen atoms in 23.6 grams of aspartame.

What are the respective concentrations (m) of na+ and so42- afforded by dissolving 0.500 mol na2so4 in water and diluting to 1.33 l?
The concentrations of Na+ and SO42- ions after dissolving 0.500 mol Na2SO4 in water and diluting to 1.33 L are respectively 0.752 mol/L and 0.376 mol/L.
Explanation:
The question asks for the calculation of concentrations of Na+ and SO42- ions after dissolving 0.500 mol Na2SO4 in water and diluting to 1.33 L.
For each formula unit of Na2SO4 that dissolves, two Na+ ions and one SO42- ion are produced. Therefore, we expect the concentration of Na+ ions to be twice that of the SO42- ions.
Concentration is calculated using the formula: Concentration = Moles/Volume. By substituting the values, we get: Concentration of Na2SO4= 0.500 mol / 1.33 L = 0.376 mol/L. As previously mentioned, the concentration of Na+ ions is double this, so it is 0.376 x 2 = 0.752 mol/L, while the concentration for SO42- ions remains 0.376 mol/L.

The volume of 1.0 kg of lead is 88.5 cm³.
Explanation:To find the volume of 1.0 kg of lead, we need to divide the mass of lead by its density. The density of lead is given as 11.3 g/cm3. First, we need to convert the mass of lead from kg to g by multiplying it by 1000 (since there are 1000 g in 1 kg). So, 1.0 kg of lead is equal to 1000 g. Now we can use the density formula: Density = Mass/Volume. Rearranging the formula gives us Volume = Mass/Density. Plugging in the mass of lead (1000 g) and the density of lead (11.3 g/cm3), we get: Volume = 1000 g / 11.3 g/cm3 = 88.5 cm3. Therefore, the volume of 1.0 kg of lead is 88.5 cm3.

If the reaction equation is reversed, the value of Kp is also reversed 2. if the reaction coefficient is divided by a factor n, then the new Kp value is the square root of n from the old Kp 3. if the reaction coefficient is multiplied by the factor n, then the new Kp value is the power of n from the old Kp2COF₂ (g) ⇌CO₂(g) + CF₄ (g) Kp = 2.2 × 10⁶ at 298 K(reaction 1)
[tex]\rm COF_2(g)--->\dfrac{1}{2}CO_2(g)+\dfrac{1}{2}CF_4(g) (reaction\:2)[/tex]
For the reaction 2, the reaction coefficient is divided by 2, so the new Kp value :
[tex]\rm Kp=\sqrt{2.2.10^6}\\\\Kp=1.483.10^3[/tex]

If the density of water is 1.000 g/ml, what is the mass in grams of 1.000 gallons of water?
From the question,
Density =1.00g/ml
mass =?
volume = 1.000 gallons.
1 gallon of water = 3.785litre
D = M/v
D is Density
m is mass
v is volume.
Mass= Volume × Density
convert the volume to mililitre
1 litre = 1000ml
3.785 × 1000 = 3785 mililitres.
Therefore, mass = 3785 ×1
mass= 3785g
What is Density?Density is the ratio of mass of a substance to it's volume.
it is Mass÷volume.
Therefore, mass is 3785g.
