Given the following reaction, what is the correct balanced chemical reaction equation? Ca(OH)₂ + HCl ? CaCl₂ + H?O

Question

Quizplus · Accepted Answer

For an equation to balance, the left-hand side must equal the right-hand side. In the original equation, we see that we first need 2 Cl's on the left-hand side (since a product is CaCl₂), so there must be 2 HCl. If there are two HCl's, then there must be 2 water molecules in order to balance the hydrogen atoms. Thus, answer A is correct.
