Question

I've got a balanced equation that is asking about and i have no idea where to start. I will attach the question below: 4A + 3B2 -> 2A2B3 If 12 moles of A are reacted with excess B2, how many moles of A2B3 will be produced?

Answer 1

6 mol of A₂B₃ are produced

Step-by-step explanation:

This is the reaction:

4A + 3B₂ → 2A₂B₃

4 moles of A react with 3 moles of B to produce 2 moles of A₂B₃.

Ratio is 4:2. Therefore:

4 moles of A will produce 2 moles of A₂B₃

12 moles of A, would produce (12 .2) / 4 = 6 moles
