Question

when excess stomach acid is treated, reaction takes place in your stomach: mg(oh)₂ + 2hcl → in the neutralization reaction, the products are a a metallic salt. b a salt and water. c carbon dioxide and water. d water, which has a neutral ph.

Explanation:

The reaction is a neutralization between a base ($\ce{Mg(OH)2}$) and an acid ($\ce{HCl}$). The products of a neutralization reaction between a metal hydroxide and an acid are a salt (from the metal and acid anion) and water. Completing the reaction: $\ce{Mg(OH)2 + 2HCl -> MgCl2 + 2H2O}$, where $\ce{MgCl2}$ is the salt and $\ce{H2O}$ is water. Option B matches this.

Answer:

B. a salt and water
