Cu heated chemical equation
WebWrite a balanced equation describing each of the following chemical reactions. (a) Solid potassium chlorate, KClO 3, decomposes to form solid potassium chloride and diatomic oxygen gas. (b) Solid aluminum metal reacts with solid diatomic iodine to form solid Al 2 I 6. (c) When solid sodium chloride is added to aqueous sulfuric acid, hydrogen chloride gas … WebWhile a physical change can often be reversed, a chemical change typically cannot be, except through more chemical reactions. When a chemical change occurs, there is also a change in the energy of the system. A chemical change that gives off heat is called an exothermic reaction. One that absorbs heat is called an endothermic reaction.
