How do I write a balanced chemical equation for hydrochloric acid in a neutralized by calcium hydroxide in a double replacement reaction

Answer 1

To write a balanced chemical equation for the neutralization of hydrochloric acid by calcium hydroxide in a double replacement reaction, you need to first write the chemical formulas for each compound:

Hydrochloric acid: HCl
Calcium hydroxide: Ca(OH)2

The balanced chemical equation for the neutralization reaction between hydrochloric acid and calcium hydroxide is:

2HCl + Ca(OH)2 -> 2H2O + CaCl2

This equation shows that two moles of hydrochloric acid react with one mole of calcium hydroxide to produce two moles of water and one mole of calcium chloride. The equation is balanced because the number of atoms of each element is the same on both sides of the reaction arrow.
