2 g of silver chloride is taken in a china dish and the china dish is placed in sunlight for sometime. What will be your observation in this case? Write the chemical reaction involved in the form of a balanced chemical equation. Identify the type of chemical reaction.

Explanation

### Step-by-Step Text Solution:

1. **Observation**: When 2 grams of silver chloride (AgCl) is placed in sunlight, the initial observation is that the silver chloride is white in color. After some time in sunlight, the silver chloride decomposes, and the observation changes to a gray color due to the formation of metallic silver.

2. **Chemical Reaction**: The chemical reaction that occurs when silver chloride is exposed to sunlight can be represented by the following balanced chemical equation:
\[ 2 \text{AgCl} (s) \xrightarrow{\text{light}} 2 \text{Ag} (s) + \text{Cl}_2 (g) \]
