Write the balanced chemical equations when hypophosphorus acid is heated.

Explanation

To write the balanced chemical equations when hypophosphorus acid (H₃PO₂) is heated, we follow these steps:

### Step 1: Identify the Reactants and Products
Hypophosphorus acid (H₃PO₂) is the reactant. Upon heating, it decomposes to form two products: phosphine (PH₃) and phosphoric acid (H₃PO₄).

### Step 2: Write the Unbalanced Equation
The unbalanced equation can be written as:
\[ \text{H}_3\text{PO}_2 \rightarrow \text{PH}_3 + \text{H}_3\text{PO}_4 \]
