1 answer:
Answer : The total mass of oxygen gas released in the reaction will be, 12.8 grams
Explanation :
Law of conservation of mass : It 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 mass on the reactant side must be equal to the total mass on the product side.
The balanced chemical reaction will be,
According to the law of conservation of mass,
Total mass of reactant side = Total mass of product side
Total mass of = Total mass of
or,
Total mass of = Mass of
+ Mass of
As we are given :
Total mass of = 16.12 grams
The mass of = 9.72 grams
So,
Total mass of = Mass of
+ Mass of
Therefore, the total mass of oxygen gas released in the reaction will be, 12.8 grams

<h2>Acetic Acid</h2>
Explanation:
- Initial alcohol that is formed from methane is methanol that can be converted to acetic acid.
- Methanol in presence of
and hydrogen gas gets oxidized to acetic acid with the release of water.
Hence, compound A will be Acetic acid.
→
- The acetic acid formed can be transformed into -

Answer:
Mass of KNO3 in the original mix is 146.954 g
Explanation:
mass of in original 254.5 mixture.
moles of
moles of
= 0.2926 mol of BaSO4
Therefore,
0.2926 mol of BaCl2,
mass of
= 60.92 g
the AgCl moles
= 1.3891 mol of AgCl
note that, the Cl- derive from both,
so
mole of Cl- f NaCl mol of Cl-
mol of NaCl = 0.8039 moles
then
KNO3 mass = 254.5 - 60.92-46.626 = 146.954 g of KNO_3
Mass of KNO3 in the original mix is 146.954 g
