A small amount of calcium oxide is taken in a beaker and water is adde

1.	A small amount of calcium oxide is taken in a beaker and water is added slowly to i(0 Will there be any change in temperature of the contents? Explain.(i) Name and define the type of reaction taking place.(ii)Write chemical equation for the above reaction.
Answer» (i) Yes,tempetaturerises as the beaker gets hot. This is becauselargeamount of heat is released or the reaction is exothermic. (ii) Combination reaction- Reaction in which a single product is obtained from two or more reactants. (iii) CaO+H2O→Ca(OH)2+heat CaO-Quick lime Ca(OH)2-Slaked lime

(i) Yes,tempetaturerises as the beaker gets hot. This is becauselargeamount of heat is released or the reaction is exothermic.

(ii) Combination reaction- Reaction in which a single product is obtained from two or more reactants.

(iii) CaO+H2O→Ca(OH)2+heat

CaO-Quick lime

Ca(OH)2-Slaked lime
