c) Insoluble salts are made by precipitation. An equation for the preparation of barium sulfate is given below. BaCl2jag) + MgSO stag) → BaSO. + Mg Claa) This reaction can be used to find x in the formula for hydrated magnesium sulfate MgSO4.XH2O. A known mass of hydrated magnesium sulfate, MgSO4.XH20, was dissolved in water. Excess aqueous barium chloride was added. The precipitafe of barium sulfate was filtered, washed and dried. Finally it was weighed. Mass of hydrated magnesium sulfate = 1.476 g Mass of barium sulfate formed = 1.398 g The mass of one mole of BaSO4 = 233 g​

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.

did anyone actually do this? like if anyone has submitted this i rly need .

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
