#### Homework Answers

Answer #1

1)

5A + 8B ↔ 8C + 4D

How many moles of B are required to produce 4 moles of D?

ratio of B:D --> 8:4 that is, we need 8 mol of B to produce 4 mol of D

2)

2A + 1B ↔ 7C + 1D

How many moles of D are produced when 7 moles of C are produced?

ratio is 7C:1D; therefore, w eneed 1 mol of D to produce 7 of C

3)

3A + 3B ↔ 4C + 2D

How many moles of C can be produced from 6 moles of B?

ratio is 3B:4C

then

4/3C: B

if we want 6 mol of C we need 1.5*3 = 4.5 mol of B

4)

3A + 2B ↔ 7C + 2D

How many moles of A are required to react with 7 moles of B?

ratio is 3:2

then 1.5 mol of A are needed for 1 mol fo B

therefore

1.5*7 = 10.5 mol of A
