For the following reaction:
A + 3B �¨ 4C
Which of the following provides the direct link between the amount of reactant A and the amount of product C?
You didn't provide any choices but the correct answer is the coefficients for A and C. The balanced equation tells you that 1 mol A will produce 4 mols C IF there is enough B present.
the coefficients provide a direct link
To determine the direct link between the amount of reactant A and the amount of product C in the given reaction:
1. Examine the balanced equation: A + 3B → 4C
This equation shows that for every one mole of A, three moles of B are required to produce four moles of C.
2. Based on the balanced equation, the stoichiometric ratio between A and C is:
1 mole A → 4 moles C
Therefore, the direct link between the amount of reactant A and the amount of product C is a 1:4 ratio. For every mole of A that reacts, four moles of C are produced.
