2 A + 4 B → 2 C How many mol of B must react with excess A to produce 2 mol of C?
1 answer:
Answer:
4 mol B
Explanation:
Step 1: Write the balanced generic equation
2 A + 4 B → 2 C
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of B to C is 4:2.
Step 3: Calculate the moles of B needed to produce 2 moles of C
2 mol C × 4 mol B/2 mol C = 4 mol B
