Question

question 3 (1 point)
if ion x has a charge 2+ and ion y has charge 3-, then the formula of a compound made up of these two ions is
x₃y₂
xy
x₂y₃
x₂y₂

Explanation:

Step1: Determine the ratio of ions

To form a neutral compound, the total positive charge must equal the total negative charge. Let the number of \(X^{2 +}\) ions be \(m\) and the number of \(Y^{3-}\) ions be \(n\). Then \(2m=3n\).

Step2: Find the smallest whole - number ratio

The smallest non - zero whole numbers \(m\) and \(n\) that satisfy \(2m = 3n\) are \(m = 3\) and \(n=2\) (by cross - multiplying \(m/n=3/2\)).

Answer:

\(X_{3}Y_{2}\)
