Write balanced chemical equations for the following:
Action of hydrochloric acid on a metal hydrogen carbonate.

Explanation

To write the balanced chemical equation for the action of hydrochloric acid on a metal hydrogen carbonate, we will use sodium hydrogen carbonate (NaHCO₃) as an example. Here’s a step-by-step solution:

### Step 1: Identify the reactants
The reactants in this reaction are sodium hydrogen carbonate (NaHCO₃) and hydrochloric acid (HCl).

### Step 2: Write the unbalanced equation
The unbalanced equation for the reaction is:
\[ \text{NaHCO}_3 (s) + \text{HCl} (aq) \rightarrow \text{NaCl} (aq) + \text{H}_2\text{O} (l) + \text{CO}_2 (g) \]
