Dear Shweta
 
Please ask one question in one thread.
 
Quick lime (CaO) is heated with silica (SiO2) to give calcium silicate called as slag.
Reaction
CaO(s) + SiO2(s) --------> CaSiO3

When sodium metal is placed in water a vigorous reaction takes place with the formation of sodium hydroxide and hydrogen .The reaction is so vigorous that hydrogen produces catches fire . And. When quicklime reacts with silica it forms calcium silicate
