Question

explain the following terms with example ​

Answer 1

Exothermic reaction : During a reaction when heat is liberated. Combination reaction : when two or more substances combine to form a single product. Displacement : when more reactive elements can displace the less reactive elements according to law of conservation of mass atoms can neither be created nor be destroyed. Hence no. Of atoms present in reactants should be equal to no. Of atoms present in product

Answer 2

endothermic reaction - in which heat is given out

combination reaction - in which two or more substance combined to form single substance

balanced equation - the mass and charge are balanced on both sides

displacement reaction - a reaction in which more reactive element react to less reactive element

hope it helps you!!!
