Wed, 03 Jul 2024 01:55:27 +0000DCombustion is an exothermic reaction because heat is converted to chemical energy. The energy needed to start a chemical reaction is called the activation energy - it's the energy needed to make the reaction active. Follow the simple instructions below: Are you still seeking a quick and efficient solution to complete Exothermic And Endothermic Reactions Worksheet at a reasonable price? A chemical reaction can be either exothermic or endothermic. In an endothermic reaction (on the right), the energy of the chemicals starts low and ends higher.
