Write the chemical formulas and names of the binary acids and oxoacids that contain group 7a elements. do the same for elements in groups 3a, 4a, 5a, and 6a.

Explanation:

Group 7A elements denote halogens so , binary acids are as follows

HF , HCl , HBr , HI .

Oxoacids are as follows

HOF , HOCl , HOClO, HOClO₂ , HOClO₃ , HOBr , HOBrO₂ ,HOBrO₃ ,

HOI , HOIO₂ , HOIO₃

For other groups

H₂S , H₃O⁺ , HCN, H₂SO₄ , H₂SO₃, HNC,HNO₃, HNO₂,H₂N₂O₂,NH₃,H₂CO₃,HN₃,H

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.
