when you have an upset stomach and you take an antacid, this unbalanced reaction occurs.

what set of coefficients will balance this equation?
a) 1,1,1,1,1
b) 2,3,3,1,3
c) 2,1,1,1,1
d) 2,2,2,1,3

The correct answer is Option C.

Explanation:

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.

it should be all of them because it asks if you included all of those in your answer

explanation:

the correct answer would be d. hope this !
