The gobar gas is a mixture of all of the given gases,except

Options

A. `CH_4`
B. `NO_2`
C. `CO_2`
D. `H_2S`

Answer

To solve the question regarding the composition of gobar gas, we need to identify which gas is not a component of this mixture. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand Gobar Gas Composition
Gobar gas, also known as biogas, is primarily produced through the anaerobic digestion of organic matter. It is mainly composed of several gases.

### Step 2: Identify the Common Components of Gobar Gas
The main components of gobar gas include:
- Methane (CH4)
- Carbon Dioxide (CO2)
- Hydrogen Sulfide (H2S)
- Hydrogen (H2)
- Water vapor (H2O)

### Step 3: Analyze the Given Options
The options provided in the question are:
1. CH4 (Methane)
2. NO2 (Nitrogen Dioxide)
3. CO2 (Carbon Dioxide)
4. H2S (Hydrogen Sulfide)

### Step 4: Compare Each Option with Gobar Gas Composition
- **CH4**: Present in gobar gas.
- **NO2**: Not present in gobar gas.
- **CO2**: Present in gobar gas.
- **H2S**: Present in gobar gas.

### Step 5: Conclusion
From the analysis, we can conclude that the gas that is not a component of gobar gas is **NO2** (Nitrogen Dioxide).

### Final Answer
The gas that is not found in gobar gas is **NO2**.
