Final answer:
The correct whole number coefficient for ammonia in a balanced chemical equation is 2, indicating that 2 moles of ammonia are produced from 1 mole of nitrogen and 3 moles of hydrogen. Therefore correct option is (2)
Step-by-step explanation:
The correct whole number coefficient for ammonia (NH₃) in a balanced chemical reaction is 2. When interpreting a balanced chemical equation, in this case, N₂ (g) + 3 H₂ (g) → 2 NH₃ (g), we understand that 1 mole of nitrogen reacts with 3 moles of hydrogen to produce 2 moles of ammonia. This relationship is significant in stoichiometry, which is used to calculate the quantities of reactants and products involved in chemical reactions.
The balanced equation represents the smallest set of whole numbers that can describe the relative amounts of reactants and products in a chemical reaction, also known as the mole ratio. In this reaction, the mole ratio is particularly important because it helps determine the amount of product formed from given amounts of reactants.
