Answer to Question 1

ANS:
Air is a colorless, odorless, and tasteless mixture of gases. It occurs in the atmosphere around the Earth and is composed of approximately 78 percent nitrogen, 21 percent oxygen, and a 1 percent mixture of argon, carbon dioxide, neon, helium, and other gases.



Answer to Question 2

ANS:
Most smoke and exhaust from homes, factories, or motor vehicles contain harmful sulfur compounds unless special equipment is used to remove them. Once these invisible gases are in the air, they combine with moisture to form sulfuric acid, which falls as acid rain.
