What is the stoichiometric factor between N? and NO in the following balanced chemical equation? N? + O? ? 2NO Select the correct answer below: 1 N? : 2 NO 1 N? : 1 NO 2 N? : 1 NO 2 N? : 2 NO
The Correct Answer and Explanation is:
The balanced chemical equation for the reaction between nitrogen and oxygen to form nitrogen monoxide (NO) is:
N2+O2→2NON_2 + O_2 \rightarrow 2NON2+O2→2NO
To determine the stoichiometric factor between N2N_2N2 (nitrogen) and NONONO (nitrogen monoxide), we look at the coefficients in the balanced equation.
- The coefficient of N2N_2N2 is 1.
- The coefficient of NONONO is 2.
This tells us that for every 1 mole of N2N_2N2, 2 moles of NONONO are produced. Therefore, the stoichiometric factor between N2N_2N2 and NONONO is 1:2.
Explanation:
The stoichiometric factor in a chemical reaction represents the ratio in which the reactants and products combine or are produced. It is derived directly from the coefficients in the balanced chemical equation.
For example, if you start with 1 mole of N2N_2N2, the equation tells us that 2 moles of NONONO will be produced, meaning the ratio of N2N_2N2 to NONONO is 1:2. Conversely, if you had 2 moles of NONONO, you would need 1 mole of N2N_2N2 to react completely.
Understanding stoichiometric factors is crucial for performing mole-to-mole conversions in chemical calculations. For instance, if you were given a certain amount of nitrogen and wanted to know how much nitrogen monoxide would be produced, you’d multiply the number of moles of N2N_2N2 by the stoichiometric factor (1 mole of N2N_2N2 produces 2 moles of NONONO).
Thus, the correct answer is: 1 N₂ : 2 NO.
