www.campbell.k12.ky.usEnergy level diagrams for exothermic reactions In an exothermic reaction, reactants have more energy than the products . The difference between these two energy levels is the energy released to the surroundings, shown as a vertical drop from a higher to a lower level. Because the reactants have more energy than the products they are less stable.
Chemical Reactions of Copper and Percent Yield

Electricity can be used to "split" water into hydrogen and oxygen. This is the basis of the fuel cells in the hydrogen powered vehicle. 3. Combustion of methane (hydrocarbons) Reaction: CH ...
