Answer 2

Answer:

(iii) 3 and 4

• Incinerators contribute a lot to air pollution, as they release toxic fumes into the environment. The carbon release after incinerations because of the burning of non-recyclable plastic waste is becoming a major climate issue. Bottom ash which is produced after incineration is around 25-30% of the weight of the waste put into incinerators and fly ash is produced by around 3% of the weight, which is contributing to air pollution.
• Hydrochloric acid (HCl) is an important acid in gastric juice. It does not attack the digestive system, nose, and eyes. The purpose of HCl is to aid in digestion by catalyzing the activation of inactive enzymes, such as pepsinogen to pepsin that break down the protein component of the food. It kills bacteria in the stomach by maintaining acidic pH-1.6. The mucus protects the stomach lining from HCl.
