Sorry, can't help ):

Answer 7

No anybody else that can?

Answer 9

The reaction releases energy as it takes place. It is exothermic. What is the sign of delta H for an exothermic reaction?

Answer 10

Triangle H?

Answer 13

Which of these three choices would you select?
(Triangle)H > 0

(triangle) H < 0

(triangle) H = 0

Answer 14

H=0?

Answer 15

@ghuczek

Answer 16

It can't be zero. The diagram shows that the products are at a lower enthalpy level than the reactants.

Answer 17

So H>0

Answer 18

The change in enthalpy is positive for an endothermic reaction.

Answer 19

So is H>0 not correct?

Answer 20

@ghuczek

Answer 21

Delta H is positive for endothermic reactions.
Delta H is negative for exothermic reactions.

Answer 22

So which one is it?

Answer 23

Delta H is negative.

Answer 24

Standard enthalpy change formation, which is the energy absorbed by the reactants to make the product. However, most of the energy was released by the products as a result, the H<0.
