B) Dalton's law
Explanation:
Dalton's law of total pressure of mixture of gases is the sum of the partial pressure of the gases that makes them up.
The law states that "the total pressure of a mixture of gases is equal to the sum of the partial pressures of the constituent gases".
Pt = P1 + P2 + P3 .....Pn
where:
Pt is the total pressure of gas mixture
P1,P2,P3,...Pn = partial pressure of gases 1,2,3...n respectively
A partial pressure is the pressure a gas would exert if it occupies the volume of a container alone

The Lewis dot structure of Mg²⁺ is shown in the picture attached.
In Mg atom, the outermost orbit has 2 electrons.
The atom has the ability to lose its 2 electrons to become Mg²⁺
The Mg²⁺ ion have completed its vacancy in the second orbit having 8 electrons.
Therefore, the valency of Mg becomes 2+ as it loses its electron.
The elements are electrically neutral, this is they have the same amount of positive as negative charge.
Electrons and protons have each the same amount of charge but different sign. Eletrons are negative and protons are positive.
Then to be neutral, the number of electrons must be equal to the number of protons. This mean that the element must have 12 electrons.
Answer: 12.
Answer:
the volume must be higher
