C Correct answer
Explanation

Acid rain contains primarily sulphuric acid (from sulfur dioxide emissions) and nitric acid (from nitrogen oxides), which react with water vapor in the atmosphere. These strong acids lower the pH of rain, damaging ecosystems and infrastructure. Oxalic, acetic, and carbolic acids are not components of natural acid rain.

Multiple choice

The hydroxide of the element belonging to period 3 and group 13 will be

  1. an alkali

  2. acidic in nature

  3. basic in nature

  4. amphoteric in nature

  5. neutral

D Correct answer
Explanation

The element in question is aluminium as it has the electronic configuration 2, 8, 3. This metal is amphoteric in nature; it reacts with both acids and alkalis. Hence, its oxide and hydroxide are amphoteric in nature.
