1.	Oxide of a metal on treatment with water produces hissing sound and energy.The product (Y) formed on treatment with hydrochloric acid gives a solid 'X'. ldentify the oxide, the product (Y) and X . Also write all the balanced chemical equations and calculate molecular masses of the oxide, the product (Y) and X .
Answer» Solution :Calcium oxide on treatment with water produces hissing sound and ENERGY. `CaO+H_2Oto underset("PRODUCT (Y)")(Ca(OH)_2)` `Ca(OH)_2+2HCltounderset((X))(caCl_2)+2H_2O` Molecular MASS of CaO `=40+16=56` Molecular mass of `Ca(OH)_2=40+2(17)=74` Molecular mass of `CaCl_2=40+2(35.5)=111`
