Question

Why carbon dioxide is heavier than air?​

Answer 1

Explanation:

 This is because carbon dioxide have higher density than other gases ( nitrogen ,oxygen, hydrogen etc.).

Answer 2

Answer:

Because it has higher density.

Explanation:

Carbon dioxide has one carbon atom and two oxygen atoms, and a molecular weight of 44 grams per mole ( a certain number of molecules). The oxygen in the air is actually O2, or molecular oxygen, with a molecular weight of 32. Hence, carbon dioxide has a higher density, or is heavier than oxygen.

As a conclusion Carbon diaoxide has an extra atom and hence its heavier than air
