WebReactions and temperature changes Energy is conserved in chemical reactions, so the total amount of energy in the universe at the end of a reaction is the same as it was before the reaction. Webthe first part of this statement is correct and would gain you a mark. but going on to write that an acid has pH greater than 7 is incorrect, and you would lose a mark for this - cancelling out the first.
