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
Solution
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.
