**Question 6: Understanding the Balanced Chemical Equation**

The balanced equation \( \text{N}_2(g) + 2 \, \text{O}_2(g) \rightarrow 2 \, \text{NO}_2(g) \) describes a chemical reaction involving nitrogen and oxygen gases to form nitrogen dioxide. To ascertain the accurate interpretation of this chemical reaction, consider the following options and determine whether option (a) or (b) correctly represents the reaction:

a. One mole of nitrogen reacts with two moles of oxygen to form two moles of nitrogen dioxide.

b. One gram of nitrogen reacts with two grams of oxygen to form two grams of nitrogen dioxide.

**Explanation:**

The coefficients in a balanced chemical equation refer to the moles of each substance involved in the reaction. Therefore, option (a) is accurate as it reflects the stoichiometry of the reaction in terms of moles, not mass. Option (b) is incorrect because it incorrectly applies mass to the equation rather than moles, which is crucial for balancing chemical reactions.
