Rbse Book Class 10 Science Chapter 1 Chemical Reactions And Equations Example –. → on the basis of heat, reactions are classified in two parts. (a) exothermic reaction – reactions in which heat is given out along with the products are called exothermic reactions. example ch 4 (g) 2o 2 (g) → co 2 (g) 2h 2 o (g) energy. (b) endothermic reaction reactions in which energy is absorbed are known as. Answer: (a) when an element displaces another element from its compound. this process is called displacement reaction. here a in (i) is znso 4 and a in (ii) is baso 4. question 5. identify x, y and z in the following equations: answer: x = cuco 3, y = h 2 s, z = so 2. question 6.
