Answer 1

? what does this picture mean

Answer 2

It's exactly the same as the picture you posted, i merely added the label of the change in enthalpy, \(\Delta H\), so you can use it to know what your answer should be.

Answer 3

okay so the answer would be 50?

Answer 4

no, \(\Delta \) means change (or difference). Change from the initial to the final state.

What was the initial state? what is the final (50 kJ/mol)? what is the difference?
