predict the products of the reaction below. that is, complete the right - hand side of the chemical equation. be sure your equation is balanced. hcl + ca(oh)₂ →

Answer

Explanation:

Step1: Identify reaction type

This is an acid - base neutralization reaction. HCl is an acid and Ca(OH)₂ is a base. The products of an acid - base neutralization reaction are a salt and water.

Step2: Determine salt formation

The cation from the base (Ca²⁺) and the anion from the acid (Cl⁻) combine to form the salt CaCl₂. The hydrogen from the acid and the hydroxide from the base combine to form water H₂O.

Step3: Balance the equation

The unbalanced equation is HCl + Ca(OH)₂ → CaCl₂ + H₂O. There are 2 Cl atoms in CaCl₂, so we need 2 moles of HCl. Also, there are 2 OH⁻ groups in Ca(OH)₂, which will produce 2 moles of H₂O. The balanced equation is 2HCl + Ca(OH)₂ → CaCl₂ + 2H₂O.

Answer:

CaCl₂ + 2H₂O
