The oxidation number of V and Al in each ion is +3 and +4 respectively.
<h3>What is oxidation number in chemistry?</h3>
oxidation number, also called oxidation state, the total number of electrons that an atom either gains or loses in order to form a chemical bond with another atom.
<h3 /><h3>Why is it called oxidation number?</h3>
The term oxidation was first used by Antoine Lavoisier to signify the reaction of a substance with oxygen. Much later, it was realized that the substance, upon being oxidized, loses electrons, and the meaning was extended to include other reactions in which electrons are lost, regardless of whether oxygen was involved.

Answer:
Molecular formula = C₅H₁₀
Explanation:
From the question given above, the following data were obtained:
Empirical formula of compound => CH₂
Molar mass of compound = 70.1 amu
Molecular formula of compound =...?
The molecular formula of a compound is usually a multiple (n) of the empirical formula i.e
Molecular formula = [CH₂]ₙ
Thus, to obtain the molecular formula of the compound, we must first determine the value of n. The value of n can be obtained as follow:
[CH₂]ₙ = 70.1
[12 + (2×1)]n = 70.1
[12 + 2]n = 70.1
14n = 70.1
Divide both side by 14
n = 70.1 / 14
n = 5
Molecular formula = [CH₂]ₙ
Molecular formula = [CH₂]₅
Molecular formula = C₅H₁₀
Thus, the Molecular formula of the compound is C₅H₁₀.
Answer:
double replacement ...i think ^^
i hopefully its right
