Write chemical equation for thermal decomposition of ammonium dichromate.

Explanation

To write the chemical equation for the thermal decomposition of ammonium dichromate, we need to follow these steps:

### Step 1: Identify the formula of ammonium dichromate
Ammonium dichromate is represented by the chemical formula \( \text{(NH}_4)_2\text{Cr}_2\text{O}_7 \).

### Step 2: Understand the process of thermal decomposition
Thermal decomposition involves breaking down a compound into simpler substances when heated. In this case, we will heat ammonium dichromate.
