___HCl + ___CaCO3 → ___CaCl2 + ___H2O + ___CO2
2 answers:
<u>Answer:</u> The correct answer is Option C.
<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.
In a chemical equation, number of individual atoms on reactant side must be equal to the total number of individual atoms on product side.
To balance the given unbalanced chemical equation, the chemical equation follows:
By Stoichiometry of the reaction,
2 moles of hydrochloric acid reacts with 1 mole of calcium carbonate to produce 1 mole of calcium chloride, 1 mole of water and 1 mole of carbon dioxide.
Hence, the correct answer is Option C.

Answer: 9.9 grams
Explanation:
To calculate the moles, we use the equation:
a) moles of
b) moles of
According to stoichiometry :
1 mole of combine with 1 mole of
Thus 0.33 mole of will combine with =
mole of
Thus is the limiting reagent as it limits the formation of product.
As 1 mole of give = 1 mole of
Thus 0.33 moles of give =
of
Mass of
Thus theoretical yield (g) of produced by the reaction is 9.9 grams
