Explanation / Answer

1)

This reaction is -1*given reaction

So,

delta H = -1* given delta H

= -1*(-132 KJ)

= 132 KJ

Answer: 132 KJ

2)

This reaction is (-1/3)*given reaction

So,

delta H = (-1/3)* given delta H

= (-1/3)*(-132 KJ)

= 132/3 KJ

= 44.0 KJ

Answer: 44.0 KJ

3)

This reaction is 2*given reaction

So,

delta H = 2* given delta H

= 2*(-132 KJ)

= - 264 KJ

Answer: - 264 KJ
