Question

Ca(oh)2(s) + hcl(aq) → cacl2(aq) + h2o(l)

Answer 1

Ответ:

Ca(OH)₂(s) + 2HCl(aq) = CaCl₂(aq) + 2H₂O(l)

Answer 2

The balanced chemical equation for the reaction between solid calcium hydroxide (Ca(OH)2) and hydrochloric acid (HCl) to form calcium chloride (CaCl2) and water (H2O) is:

Ca(OH)2(s) + 2HCl(aq) → CaCl2(aq) + 2H2O(l)

In this equation, one mole of solid calcium hydroxide reacts with two moles of hydrochloric acid to produce one mole of calcium chloride and two moles of water. The coefficients in the balanced equation indicate the ratio in which these substances react and are produced in the chemical reaction.
