Question

What does one mean by exothermie and endothermie reactions? Give example​

Answer 1

reaction in which heat energy is liberated by the reactants is called exothermic reaction. eg: Carbon + Oxygen gives Carbon Dioxide + Q. reaction in which heat energy is absorbed by the reactants is called endothermic reaction. eg: Nitrogen + Oxygen gives 2 nitrous oxide (2NO) - Q.

have a nice day

plz mark as brainliest n follow

BTSplease mark me as brainliest

BTSplease mark me as brainliestExothermic reactions : Those reactions in which heat is evolved are known as exothermic reactions. An exothermic reaction is indicated by writing “+ Heat”on the products side of an equation.
