Do not attempt to perform this demonstration. The combustion of methane is an example of an exothermic reaction. More energy is released when the bonds in the products are formed than is used to break ...

Every chemical reaction involves a change in energy because different substances hold different amounts of energy. During the reaction, bonds inside the substances that are reacting together must ...

3 Use the chemical equation to work out how many ... 7 Calculate the overall energy change (energy in - energy out). Action Calculate the overall energy change (energy in - energy out).

When two atoms or molecules that are attracted to each other are together, it takes energy to break them apart. When two atoms or molecules that are attracted to each other are apart, energy is ...
