Unformatted text preview: water or cooking a egg. When a chemical reaction happens, there can be a net transfer of energy from the reactants into the surroundings (e.g. air, water is in solution) or a net transfer of energy from the surroundings tothe reactants causing a change in average kinetic energy of the particles in the surrounding and a proportional change in the temperature. With a Exothermic reactions the energy is transferred from the reaction system into the surroundings. In thes The average kinetic energy of the surroundings increases causing the reaction mixture to increase in temperature and get warmer. Some examples of exothermic reactions are: Burning ( combustion) Neutralization reactions between acids and alkalis The reaction between water and calcium oxide...
