Read the given passage and answer the following
questions.
Sanjana while preparing cake used baking soda in small amounts. It helps to make the cake soft land spongy. An aqueous solution of baking soda also turns red litmus blue. It is also used in soda acid extinguisher.
Name the products formed when baking soda is heated:

Options

A. Sodium sulphate and carbon dioxide gas.
B. Sodium carbonate and water.
C. Sodium carbonate, carbon dioxide and water.
D. Sodium oxide carbon dioxide and water.

Explanation

To determine the products formed when baking soda is heated, we can follow these steps:

### Step 1: Identify the chemical formula of baking soda.
Baking soda is chemically known as sodium bicarbonate, which has the formula:
\[ \text{NaHCO}_3 \]

### Step 2: Write the decomposition reaction of baking soda.
When baking soda is heated, it undergoes a decomposition reaction. The balanced equation for this reaction is:
\[ 2 \text{NaHCO}_3 \rightarrow \text{Na}_2\text{CO}_3 + \text{H}_2\text{O} + \text{CO}_2 \]

### Step 3: Identify the products formed.
From the balanced equation, we can see that when baking soda is heated, it decomposes to form:
- Sodium carbonate (\( \text{Na}_2\text{CO}_3 \))
- Water (\( \text{H}_2\text{O} \))
- Carbon dioxide (\( \text{CO}_2 \))

### Step 4: List the products.
Thus, the products formed when baking soda is heated are:
1. Sodium Carbonate (\( \text{Na}_2\text{CO}_3 \))
2. Water (\( \text{H}_2\text{O} \))
3. Carbon Dioxide (\( \text{CO}_2 \))

### Final Answer:
The products formed when baking soda is heated are Sodium Carbonate, Water, and Carbon Dioxide.
