Give an example of a chemical reaction in which a tremendous amount of heat is released.
Exothermic reaction:-
2Al(s)Aluminium+Fe2O3(s)Iron(III) oxide→2Fe(s)Iron+Al2O3(s)Aluminiumoxide+heat
Therefore, a chemical reaction in which a tremendous amount of heat is released is the explosion of an atom bomb.
The chemical reaction in which heat is released is called __________ reaction.
Give an example of a chemical change in which heat is liberated.
Give two examples of chemical reactions in which heat is absorbed.
