A 3.81-gram sample of NaHCO3 was completely decomposed in an experiment.
2NaHCO3 → Na2CO3 + H2CO3
In this experiment, carbon dioxide and water vapors combine to form H2CO3. After decomposition, the Na2CO3 had a mass of 2.86 grams.
A. Determine the mass of the H2CO3 produced.
B. Calculate the percentage yield of H2CO3 for the reaction. Show your work or describe the calculation process in detail.
the mass of the H2CO3 produced = 0.351 g and the percentage yield of H2CO3 = 24.9% Solution:- 2NaHCO3 → Na2CO3 + H2CO3 since we know that no of moles = mass / molar mass molar mass…
The statement of "the mass of the H2CO3 produced is 1.31 g and the the percentage yield of H2CO3 is 96.43%."
What is percentage yield?The percentage yield is the percent ratio of actual yield to the theoretical yield. It is obtained by dividing the observed yield by the theoretical yield and multiplying by 100%.
Given:
2NaHCO3 → Na2CO3 + H2CO3
3.81 g of NaHCO3, 2.86 g of Na2CO3
Solution:
One mole of sodium carbonate and one mole of hydrogen carbonate are produced from two moles of sodium bicarbonate.
Gram to mole conversion,
[tex]3.81\;.\frac{1\;mole}{84\;g}\;=\;0.0453\;mol\;of\;NaHCO3\\2.86\;.\frac{1\;mole}{105.98\;g}\;=\;0.0269\;mol\;of\;Na2CO3[/tex]
Initially to find the mass of H2CO3, moles of H2CO3 can be calculated by using the determined moles of NaHCO3.
[tex]0.0453\;mol\;NaHCO3.\frac{1\;mol\;H2CO3}{2\;mol\;NaHCO3}\;=\;0.0227\;mol\;H2CO3[/tex]
So, the moles of hydrogen carbonate
[tex]0.0227\;mol\;H2CO3.\frac{62.03\;g\;H2CO3}{1\;mol\;H2CO3} = 1.408\;g\;H2CO3[/tex]
Therefore the mass of the product is 1.408 g.
The actual yield of H2CO3 can be determined from mass of sodium bicarbonate and sodium carbonate.
Mass of H2CO3 = Mass of NaHCO3 - Mass of Na2CO3
Mass of H2CO3 = 3.81 g - 2.86 g
Mass of H2CO3 = 0.95 g
Now the percent yield,
% yield
[tex]= \frac{experimental\;yield}{theoretical\;yield}. 100\\= \frac{0.95\;g}{1.408\;g}. 100[/tex]
= 67.47%
≈ 67.5%
Therefore, the percentage yield of the product is 67.5%.

The rate law of the overall reaction A + B → C is rate = k[A]2. Which of the following will not increase the rate of the reaction?
a. increasing the concentration of reactant B
b. adding a catalyst for the reaction
c. increasing the concentration of reactant A
d. increasing the temperature of the reactant
e. all of these will increase the rate
To solve this we need to have knowledge of experimental rate law which relates the rate to the concentration raise to some power. Therefore, the correct option is option A that is increasing the concentration of reactant B.
What is rate law?A rate law represents the rate of a reaction . According to this rate is directly proportional to the concentration of reactants. There is another expression of rate law which is integrated rate law which is just opposite of differential rate law.
The experimental rate law for given reaction is given as:
Rate = rate = k[A]²
To not to increase the rate of the reaction, we need to increasing concentration of B as there is no concentration of B in the rate law expression. Rate is independent of concentration of B.
Therefore, the correct option is option A that is increasing the concentration of reactant B.

Salicyllic acid has what ionic charge?
Answer:
0
Explanation:
It has no charge.
Salicylic acid is insoluble in water because it is a non-polar covalent compound.
For this reason it is a poor conductor of electricity as it has no free moving ions that would act as charge carriers.
But on the other hand salicylate which is a conjugate base of salicylic acid has a charge of -1 and can be written as C7H5O3-.
hopefully this makes sense

Chloric acid (HCIO3 is a neutral compound. The chlorine atom has what oxidation number?
Answer: 1
Explanation: one
Chloric acid is a neutral compound and an oxoacid with strong oxidizing power. In the compound (chloric acid), chlorine has an oxidation number of +5. Thus, option c is correct.
What is the oxidation number?The oxidation number is defined as electrons that are transferred by accepting and donating in a chemical bond formation. They denote the atoms that have gained and donated electrons by the positive and negative states.
As chloric acid is a neutral compound, the equivalent will be zero. The oxidation state of the hydrogen atom is generally taken as 1 and that of oxygen as -2 as it requires two more electrons in its valence shell.
The oxidation number will be estimated as,
HCIO₃ = 0
+1 + x + 3(-2) = 0
+1 + x - 6 = 0
x = + 6 - 1
x = + 5
Therefore, option c. chlorine has a +5 oxidation number in chloric acid.

Answer:
ll matter is composed of extremely small particles called atoms.
Atoms of a given element are identical in size, mass, and other properties. Atoms of different elements differ in size, mass, and other properties.
Atoms cannot be subdivided, created, or destroyed.
Atoms of different elements can combine in simple whole number ratios to form chemical compounds.
In chemical reactions, atoms are combined, separated, or rearranged.
Each atom is uniform, homogeneous, colorless, tasteless, and indivisible.ll atoms of a given element are identical in mass and properties. Compounds are formed by a combination of two or more different kinds of atoms. A chemical reaction is a rearrangement of atom.
The basic idea that atoms are indivisible implies that atoms cannot be divided into any known smaller fractions.
Why are atoms indivisible?John Daltons theory of matter was based on the law of conservation of mass and the law of constant composition. The first part of his theory states that all matter is made of atoms, which are indivisible.
