The question is incomplete, here is the complete question:
Write a balanced equation for the neutralization of calcium hydroxide by hydrochloric acid. What is the coefficient for hydrochloric acid in the reaction.
Answer: The balanced chemical reaction is written below and the coefficient of hydrochloric acid is 2.
Step-by-step explanation:
Neutralization reaction is defined as the reaction in which an acid reacts with a base to produce a salt and water molecule.
Balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side will be equal to the total number of individual atoms on the product side. These equations follow law of conservation of mass.
The balanced chemical equation for the reaction of calcium hydroxide and hydrochloric acid follows:
By Stoichiometry of the reaction:
1 mole of calcium hydroxide reacts with 2 moles of hydrochloric acid to produce 1 mole of calcium chloride and 2 moles of water molecule.
Hence, the balanced chemical reaction is written below and the coefficient of hydrochloric acid is 2.
