To balance the following chemical equation the value of

x

and

y

should respectively be:

2\mathrm{NaOH}+x\mathrm{Al}_2\mathrm{O}_3\rightarrow y\mathrm{NaAlO}_2+\mathrm{H}_2\mathrm{O}

Solution:

The balance chemical equation is:

\mathrm{Al}_2\mathrm{O}_3+2\mathrm{NaOH}\rightarrow 2\mathrm{NaAlO}_2+\mathrm{H}_2\mathrm{O}

Thus the value of

x

and

y

will be 1 and 2 respectively.
