1.	Sea water can't be used in boiler. Explain given chemical equations.
Answer» Solution :Sea water contains SOLUBLE salts of calcium and magnesium, which on boiling change to insoluble salts and get deposited as a crust on the inner of a boiler. This crust acts as a bad conductor of heat and PREVENT the flow of heat to water. A large QUANTITY of fuel GETS WASTED. Chemical Reaction. `CA(HCO_(3))_(2)overset(Delta)toCaCO_(3)+CO_(2)+H_(2)O` `Mg(HCO_(3))_(2)overset(Delta)toMgCO_(3)+CO_(2)+H_(2)O`
