Question

what does one mean by exothermic and endothermic reactions ?give examples.​

Answer 1

ANSWER

EXOTHERMIC REACTION

Reaction in which heat is given out along with the product are called Exothermic reactions.

For example;

= CH4(g)+2O2(g)-----)CO2(g)+2H2O(g)

ENDOTHERMIC REACTION

Reaction that obsorb energy or require energy in order to proceed are called endothermic reaction.

For example= When ammonia chloride is dissolve in water in a test tube, the test tube become cold. Thus the reaction is an example of Endothermic reaction.
