Question

To balance the following chemical equation the value of x and y should respectively be:

\[\ce{2NaOH + xAl_2O_3->yNaAlO_2 + H_2O}\]

Options

• 1, 4

• 1, 2

• 2, 4

• 2, 3

Answer 1

1, 2.

Explanation:

The balance chemical equation is:

\[\ce{Al_2O_3 + 2NaOH->2NaAlO_2 + H_2O}\]

Thus the value of x and y will be 1 and 2 respectively.
