What Is an Exothermic Reaction? Exothermic means to give off heat. The prefix exo- means out, leave, or exit; and the root therm refers to heat energy. An exothermic reaction, then, is a chemical reaction system that releases heat during the reaction process....
Identify that the reaction is exothermic, meaning it releases heat as a product. Apply Le Chatelier's Principle, which states that if a system at equilibrium is disturbed, it will shift in a direction that counteracts the disturbance....
A. heat and light B. water and carbon dioxide C. oxygen and hydrogen D. steel and other metals 相关知识点: 试题来源: 解析 A。解析:文中提到 Combustion is a chemical reaction that releases energy. This reaction releases heat and light.。反馈...
An exothermic reaction is a chemical reaction that releases energy by light or heat. It is the opposite of an endothermic reaction. An exothermic reaction will occur spontaneously, while and endothermic reaction needs energy to occur. Ammonium Nitrate reacting with water would be a good cold pack...

In the latter case each piece of wood, as it burns, must release enough heat to raise nearby pieces to the kindling point. The wood, therefore, must be piled close enough together so that not too much heat is lost to the surrounding air. The conditions for a nuclear chain reaction can...
