WebJun 1, 2024 · An example would be the combustion reaction between methane (CH 4) oxygen (O 2) (the reactants) that produces carbon dioxide (CO 2) and water (H 2 0) molecules (the products). Bonds are broken in the methane and oxygen molecules. Bonds are formed in the carbon dioxide and water molecules. Combustion of methane showing … WebReversible Reactions. Reversible reactions are ones which occur in both directions at the same time. We represent them using a double arrow: reactants products. If a reversible reaction is exothermic (gives out energy) in one direction it is endothermic (takes in energy) in the other direction. When a reversible reaction takes place in a closed ... WebAn endothermic chemical reaction is a reaction that occurs by absorbing heat energy from the surroundings, and by doing so, will cool down the surroundings of the chemical reaction. The heat energy that is absorbed by the chemical reaction process essentially ‘steals’ this from the energy of the particles that surrounds the reactant particles. clay derek alligood
