Ammonia (NH3) clouds are present around some planets. Calculate the number of grams of ammonia produced by the reaction of 5.4 g of hydrogen with an excess of nitrogen N2 + 3 H2 -> 2 NH3

30.6 g of ammonia are produced.

given

mass of hydrogen =5.4 gram

mass of NH3=?

we have

3 moles of H2=2 moles of NH3

3×2g of H2=2×(14+3) g of NH3

6 g of H2=34 g of NH3

5.4 g of H2=34×5.4/6=30.6 g of NH3

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.
