A crystalline salt when heated becomes anhydrous and losses 51.2% of its weight. The anhydrous salt on analysis gave the % composition as Mg=20% S=26.6% and O=53.33%.Calculate the molecular formula of the anhydrous salt and the crystalline salt. Molecular mass of the anhydrous salt is 120.

28. which is not a reason that water is used to store spent fuel rods from nuclear power plants? water increases the speed of the chain reaction in the fuel rods. water protects nuclear power plant workers from the high temperature and radiation of the fuel rods. water acts as a radiation shield to reduce the radiation levels. water cools the spent rods. salts action
