Answer:
C = 5mol produced
Step-by-step explanation:
To determine how many moles of C are produced from 5 moles of A and 8 moles of B, we need to use the stoichiometry of the balanced chemical equation for the reaction:
A + 2B → C
From the balanced equation, we can see that 1 mole of A reacts with 2 moles of B to produce 1 mole of C. Therefore, the number of moles of C produced will depend on the limiting reactant.
To determine the limiting reactant, we need to compare the number of moles of A and B to their stoichiometric coefficients in the balanced equation.
5 moles of A will react with 10 moles of B (since 1 mole of A reacts with 2 moles of B), so B is in excess.
Thus, A is the limiting reactant and will be completely consumed. The number of moles of C produced will be equal to the number of moles of A used, which is 5 moles.
Therefore, 5 moles of C are produced from 5 moles of A and 8 moles of B.
