(1)  Rancidity
(2)  Endothermic  reactions
(3)  Redox  reactions
(4)  Neutralization


MSCERT Class 10 General Science Ch2 The Magic of Chemical Reactions

Answer 1

if heat is absorb then it is endothermic reactions
oxidation and reduction occurs in the same reaction .if one reactants gets oxidized ,the other gets reduced such reactions r called redox reaction

Answer 2

1- Rancidity - It refers to the spoilage of a food or food poisoning.
2- Endothermic reactions - Reactions in which heat is absorbed from the                                                  surrounding or external heat is given.
3- Redox reactions - Reactions in which transfer of electrons b/w reatants                                      takes place.
