<u>Answer:</u> The identity of the unknown acid is butanoic acid or ascorbic acid.
<u>Explanation:</u>
To calculate the number of moles for given molarity, we use the equation:
Molarity of NaOH solution = 0.570 M
Volume of solution = 39.55 mL
Putting values in above equation, we get:
The chemical equation for the reaction of NaOH and monoprotic acid follows:
By Stoichiometry of the reaction:
1 mole of NaOH reacts with 1 mole of HX
So, moles of monoprotic acid = 0.0225 moles
The chemical equation for the reaction of NaOH and diprotic acid follows:
By Stoichiometry of the reaction:
2 moles of NaOH reacts with 1 mole of diprotic acid
So, moles of diprotic acid =
To calculate the number of moles, we use the equation:
- <u>For butanoic acid:</u>
Mass of butanoic acid = 2.002 g
Molar mass of butanoic acid = 88 g/mol
Putting values in above equation, we get:
- <u>For L-tartaric acid:</u>
Mass of L-tartaric acid = 2.002 g
Molar mass of L-tartaric acid = 150 g/mol
Putting values in above equation, we get:
- <u>For ascorbic acid:</u>
Mass of ascorbic acid = 2.002 g
Molar mass of ascorbic acid = 176 g/mol
Putting values in above equation, we get:
As, the number of moles of butanoic acid and ascorbic acid is equal to the number of moles of acid getting neutralized.
Hence, the identity of the unknown acid is butanoic acid or ascorbic acid.
<u>Answer:</u> The chemical equation is written below.
<u>Explanation:</u>
Every balanced chemical equation follows law of conservation of mass.
This law states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form. This also means that total number of individual atoms on reactant side must be equal to the total number of individual atoms on the product side.
The chemical equation for the reaction of elemental boron and oxygen gas follows:
By Stoichiometry of the reaction:
4 moles of elemental boron reacts with 3 moles of oxygen gas to produce 2 moles of diboron trioxide.
The chemical equation for the reaction of diboron trioxide and water follows:
By Stoichiometry of the reaction:
1 mole of diboron trixoide reacts with 3 moles of water to produce 2 moles of boric acid.
Hence, the chemical equations are written above.
