Synthesis reactions are generally characterized by being exothermic. Decomposition reactions are usually endothermic.
An endothermic reaction is one that takes in light or heat energy. For example, the enthalpy of solution for acetic acid dissolving in water is negative so it uses heat and hence is exothermic The...
yes a decomposition reaction is a chemical reaction.
Any rxn that is (generally) and organic molecule + O2 -> H2O + CO2Thats just generally what it looks like.
An Oxidation Reaction.It may also be a redox reaction.
