Statement B:
CO2 is heavier gas than both N2 and O2.
Explanation:
- The molecular weight of CO2 is 44 g/mol, which is higher than the molecular weights of N2 (28 g/mol) and O2 (32 g/mol).
- Since CO2 has a higher molecular weight, it is indeed heavier than both N2 and O2 gases.
Therefore, Statement B is true.
