Answer is: 5,9.
Effusion is leakage of gas
through a small hole. Gases with a lower molecular mass effuse more speedy than gases with a higher molecular mass. R<span>elative rates of effusion is related to the molecular mass.
</span>M(O₂) = 32g/mol.
M(CO₂) = 44g/mol.
t₁ = 5s.
t₂ = ?
t₂/t₁ = √(M(CO₂)/M(O₂)).
t₂ = 1,17·5s = 5,9s.

Answer: Sodium Nitrate solution is neutral.
Explanation: Sodium nitrate solution has strong bases and strong acids so it would have a neutral pH of 7.

Explanation:
I really dont kno but i hope im right
Lanthanoid ions are contracted when compared to the other ions. This is due to the vulnerability of the 4f electrons. The electrons are not shielded by other electrons which allow the nucleus to pull the electrons in the orbital closer. This is also the reason why the orbital motion's contribution to paramagnetism is not quenched in the ions.
