    I sat the same paper but got a different question. One of the bonds formed was a triple bond between a carbon atom and an oxygen atom. And I got 212J for that question.
    oh right! can you remember the question, or just the word equation?

    I don't know because it said on the next questioas an exothermic reaction but exothermic reactions are positive and so i am not too sure what the answer is

    I did well on C1, C2 and my controlled assessment but C3 went pretty badly for me. Is it still possible to get an A* if one of the three exams wasn't as good as the others?

    Exothermic are always negative because they're releasing/losing heat energy

    exothermic reactions give out energy to the surroundings, so the energy in the surroundings increases but the energy of the products/chemicals/whatever actually decreases

    Exothermic reactions release energy. So, the overall energy change is negative - because it loses energy to its surroundings.

    For the question where it said why air can't be allowed in the reactor I put that the oxygen reacts with the substances in the reactor and so would cause an explosion...Is this right?
