The correct Answer is:
To solve the question of which mixing gives a deep brown color, we will analyze the provided options step by step. ### Step 1: Analyze the first option (NO + O2) - **Reaction**: Nitric oxide (NO) reacts with oxygen (O2). - **Products**: The reaction produces nitrogen dioxide (NO2), which is known to have a deep brown color. - **Chemical Equation**: \[ 2NO + O2 \rightarrow 2NO2 \] - **Conclusion**: This reaction results in the formation of a deep brown gas (NO2). ### Step 2: Analyze the second option (N2O + O2) - **Reaction**: Dinitrogen monoxide (N2O) reacts with oxygen (O2). - **Products**: This reaction does not produce any significant brown-colored gas. Instead, N2O is a colorless gas and does not react to form a brown product. - **Conclusion**: This reaction does not yield a deep brown color. ### Step 3: Analyze the third option (N2O3 + O2) - **Reaction**: Dinitrogen trioxide (N2O3) reacts with oxygen (O2). - **Products**: N2O3 is also not known to produce a deep brown color upon reaction with oxygen. It is typically a blue-colored gas. - **Conclusion**: This reaction does not yield a deep brown color. ### Step 4: Analyze the fourth option (None) - This option suggests that none of the previous reactions produce a deep brown color. However, we have already established that the first option does produce a deep brown color. ### Final Conclusion: The correct answer to the question is **Option A: NO + O2**. ---
