    Endothermic means that heat is absorbed. You have checked the equations where heat is one of the products.

    Ok but, my lesson says that I missing some, and some are wrong.

    The first one and the third one are endothermic. The heat should be on the left as one of the reactants. If it is on the right, it would be negative.

    Well I'm not sure what those E1 and E2 mean. Do you know?

    Did you have the same as I had for the E questions?

    Well if it were me, I'd switch the E questions and I'm not sure about the other one. I could do a little internet research.

    If the environment becomes hotter, we have an exothermic reaction.

    So 3 and 7 must both be exothermic because it says that the final temp is greater.

    A reaction is overall exothermic if more energy is released when new bonds form in products than is used when bonds in the reactants are broken.
