Acid rain is caused by the chemical reaction that begins when compounds like sulphur dioxides and ______ are released into the air.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. nitrogen oxides.
- Acid rain is caused by the chemical reaction that begins when compounds like sulphur dioxide and nitrogen oxides are released into the air.
- When these gases mix with water vapor in the air, they form sulfuric acid and nitric acid, which then fall to the ground as acid rain.
- Acid rain can harm plants, aquatic animals, soil quality, and even man-made structures like buildings and statues.
Other Options:
Ferric oxide: Also known as iron(III) oxide, is an inorganic compound with the chemical formula Fe₂O₃. It's a common iron oxide, and is widely known as rust when it forms on iron or steel.
Zinc oxide (ZnO): It is a chemical compound made of zinc and oxygen. It’s a white powder that is widely used in many industries because of its unique properties.
Calcium oxide (CaO): It is commonly known as quicklime, is a white, caustic, alkaline solid.
