Give the balanced equations for the following reactions .
Red lead is warmed with concentrated hydrochloric acid .

Explanation

To balance the chemical equation for the reaction of red lead (lead tetraoxide, Pb3O4) with concentrated hydrochloric acid (HCl), we will follow these steps:

### Step 1: Write the unbalanced equation
The unbalanced equation for the reaction is:
\[ \text{Pb}_3\text{O}_4 + \text{HCl} \rightarrow \text{PbCl}_2 + \text{Cl}_2 + \text{H}_2\text{O} \]

### Step 2: Identify the reactants and products
- **Reactants**: Lead tetraoxide (Pb3O4) and hydrochloric acid (HCl).
