Question

Given the unbalanced equation:

- Al(SO )3 + - Ca(OH)2 +_ Al(OH)3 + caso,
What is the coefficient in front of the caso, when the equation is completely balanced with
the smallest whole-number coefficients?​
A. 1
B.2
C.3
D.4

Answer 1

3 is the coefficient in front of the
`CaSO_(4)`

The smallest whole-number coefficient is 2.

Step-by-step 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.
