Question

The amount of carbon dioxide should not cross the delicate proportion of which of the following?

(a) 0.01%

(b) 0.04%

(c) 0.3%

(d) 0.03%

This question was addressed to me in an interview for job.

My query is from Environmental Chemistry topic in division Environmental Chemistry of Chemistry – Class 11

Answer 1

Right option is (d) 0.03%

The best explanation: The amount of carbon dioxide optimum for the environment should be 0.03 per cent. If this per cent is crossed, then the natural greenhouse balance may get disturbed since carbon dioxide is the major contributor to global warming. But, low concentrations are also not desirable. It can lead to kidney diseases. This condition can cause the body’s blood acid level to go up due to the lack of insulin to digest sugars in the body.
