Consider the following reaction and select incorrect statement about gas (P):
`Zn+HNO_(3)("Dilute")toZn(NO_(3))_(2)+Puarr`

Options

A. Gives neutral solution in water
B. Contains more `O_(2)` than Air
C. Forms brownn ring with `FeSO_(4)` solution
D. None of these

Explanation

To solve the question regarding the reaction of zinc with dilute nitric acid and the properties of the gas produced (denoted as gas P), we will analyze each of the provided statements to determine which one is incorrect.

### Step-by-Step Solution:

1. **Identify the Reaction**:
The reaction given is:
\[ \text{Zn} + \text{HNO}_3 (\text{dilute}) \rightarrow \text{Zn(NO}_3)_2 + \text{P} \]
Here, zinc reacts with dilute nitric acid to produce zinc nitrate and a gas (P).

2. **Determine the Gas Produced**:
When zinc reacts with dilute nitric acid, the gas produced is typically nitrogen oxide (NO) or nitrous oxide (N2O), depending on the concentration of the acid. In this case, we will consider the gas to be nitrous oxide (N2O) since it is a common product in reactions with dilute nitric acid.

3. **Analyze Each Statement**:
- **Statement 1**: "The gas gives a neutral solution in water."
- N2O is a neutral gas and does not affect the pH of the solution significantly. Thus, this statement is correct.

- **Statement 2**: "The gas contains more oxygen than air."
- Air contains approximately 21% oxygen. N2O has a molecular formula of N2O, which contains one oxygen atom. The molar mass of N2O is 44 g/mol (28 for N2 and 16 for O). The percentage of oxygen in N2O can be calculated as:
\[ \text{Percentage of O} = \left(\frac{16}{44}\right) \times 100 \approx 36.36\% \]
This is indeed greater than 21%, making this statement correct.

- **Statement 3**: "The gas forms a brown ring with FeSO4."
- The brown ring test is characteristic of nitrogen oxides, particularly NO, but not N2O. N2O does not form a brown ring with FeSO4. Therefore, this statement is incorrect.

4. **Conclusion**:
The incorrect statement about gas P (N2O) is:
- **Statement 3**: "It forms a brown ring with FeSO4."

### Final Answer:
The incorrect statement about gas P is: "It forms a brown ring with FeSO4."
