Question

Given the unbalanced equation:

Answer 1

Answer:

3 is the coefficient in front of the $CaSO_{4}$

The smallest whole-number coefficient is 2.

Explanation:

The balanced chemical equation is as follows.

$Al_{2}(SO_{4})_{3}(aq)+3Ca(OH)_{2}(s) \rightarrow 2Al(OH)_{3}(s)+3CaSO_{4}(s)$

3 is the coefficient in front of the $CaSO_{4}$

The smallest whole-number coefficient is 2.
