Question

Identify coefficients 'x' and 'y' for the following reaction.

$$\text{x}\mathrm{H}{\phantom{A}}_2\mathrm{O}{\phantom{A}}_2{\phantom{A}}_{(\mathrm{aq})}+\mathrm{ClO}{\phantom{A}}_{4(\mathrm{aq})}^{-}⟶2\mathrm{O}{\phantom{A}}_2{\phantom{A}}_{(\mathrm{g})}+\mathrm{ClO}{\phantom{A}}_{2(\mathrm{aq})}^{-}+\text{y}\mathrm{H}{\phantom{A}}_2\mathrm{O}{\phantom{A}}_{(\mathrm{l})}$$

Options

• x = 2, y = 5

• x = 5, y = 5

• x = 5, y = 2

• x = 2, y = 2

Answer 1

x = 2, y = 2

Explanation:

$$2\mathrm{H}{\phantom{A}}_2\mathrm{O}{\phantom{A}}_2{\phantom{A}}_{(\mathrm{aq})}+\mathrm{ClO}{\phantom{A}}_{4(\mathrm{aq})}^{-}⟶2\mathrm{O}{\phantom{A}}_2{\phantom{A}}_{(\mathrm{g})}+\mathrm{ClO}{\phantom{A}}_{2(\mathrm{aq})}^{-}+2\mathrm{H}{\phantom{A}}_2\mathrm{O}{\phantom{A}}_{(\mathrm{l})}$$
