Answer:
It occurs when a gas passes through a tiny hole.
Explanation:
Effusion is a term used to describe when a gaseous molecule in a container passes or escapes through a tiny/small hole. Effusion and diffusion are two properties of gases that are often used interchangeably, however, they differ.
Effusion differs from diffusion in the sense that the gas passes through a TINY HOLE that is smaller than the normal path. This is contrary to when gas disperses throughout a container as in diffusion.
Answer:
option A= pH = 0.1
Explanation:
Given data:
Concentration of H₃O⁺ = 0.8 M
pH = ?
Solution:
pH = -log [H₃O⁺] H₃O⁺ = H⁺
pH = -log [0.8]
pH = - (-0.097)
pH = + 0.1
No because most of them are forces
