Question

A small amount of CaO is taken in a beaker and water is added slowly to it. (a) Will there be any change in temperature of the content? Explain. (b) Name and define the type of the reaction taking place. Also write the balanced chemical equation for the reaction.

Answer 1

Answer:

I) yes temperature rises as the beaker gets hot.this is because large amount of heat is released for 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-quicklime

Ca(oH)2- slaked look lime
