Answer 1

the endothermic reaction is any chemical reaction that absorbs heat from its environment . here's a list of endothermic reaction . you can use these when asked cite an example or to get ideas to set up a demonstration on endothermic reaction or process

Many chemical reactions release energy I'm the form of heat,light, or sound . these are called exothermic reaction .
Eg: rusting and combustion .

it's very simple dude u can remember it with a trick that exothermic reaction means the heat is released(exit) in environment and endothermic reaction means heat is absorbed(taken) frm environment
