balance the following equation:
x₂ + y₂ → xy₃
select the correct answer below:
o x₂ + y₂ → xy₃
o 2x₂ + y₂ → 3xy₃
o x₂ + 3y₂ → 2xy₃
o x₂ + y₂ → 2xy₃

Explanation:

Step1: Balance X - atoms

On the left - hand side, we have 2 X - atoms in $\text{X}_2$. On the right - hand side, we have 1 X - atom in $\text{XY}_3$. To balance X - atoms, if we put a coefficient of 2 in front of $\text{XY}_3$, we get 2 X - atoms on both sides.

Step2: Balance Y - atoms

After putting a coefficient of 2 in front of $\text{XY}_3$, we have 6 Y - atoms on the right - hand side ($2\times3$). On the left - hand side, we have 2 Y - atoms in $\text{Y}_2$. By putting a coefficient of 3 in front of $\text{Y}_2$, we get 6 Y - atoms on both sides. So the balanced equation is $\text{X}_2 + 3\text{Y}_2\longrightarrow2\text{XY}_3$.

Answer:

C. $\text{X}_2 + 3\text{Y}_2\longrightarrow2\text{XY}_3$
