Balance the following equation? Ca(OH)2 (s) + (NH4)2 SO4 (s) → CaSO4 (s) + H2 O (l) + NH3 (g)

Answer 1

Caleb Adams

This is simply an acid-base reaction.....where ammonium is the acid....

And thus.....

#NH_4^(+) + HO^(-) rarrNH_3(aq) + H_2O(l)#...

and so.....

#Ca(OH)_2(s) + (NH_4)_2SO_4(aq)rarr CaSO_4(s)darr+2NH_3(aq) +2H_2O(l)#

Calcium sulfate is reasonably insoluble....and precipitates from solution as a white powder.

The balanced equation is:

[ \text{Ca(OH)}_2 \text{(s)} + 2(\text{NH}_4)_2\text{SO}_4 \text{(s)} \rightarrow \text{CaSO}_4 \text{(s)} + 4\text{H}_2\text{O} \text{(l)} + 2\text{NH}_3 \text{(g)} ]

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
