Question
When hydrogen burns in air water is formed, the equation for this reaction is:
2H2(g) +O2(g) -> 2H2O(g) delta H = -484kj
A. Which has the greater amount of energy? Water or the mixture of hydrogen and oxygen? Give reason for your answer
B. Draw energy profile diagram for the reaction between hydrogen and oxygen to form water

Delta H is negative which means the reaction gives off energy and that means the reactants have more energy than the products.
