Answer:
2KOH(aq) + NiSO₂(aq) → K₂SO₄(aq) + NiOH₂(s)
Explanation:
This reaction is an example of a <em>double-replacement reaction </em>where the cations of two compounds exchange with its anions. In the reaction:
KOH(aq) + NiSO₄(aq)
There are produced K₂SO₄ and NiOH₂ salts (The last one is insoluble, its state is (s) but K₂SO₄ is very soluble, its state is (aq). The unbalanced reaction is:
KOH(aq) + NiSO₄(aq) → K₂SO₄(aq) + NiOH₂(s)
To balance the potassiums:
<h3>
2KOH(aq) + NiSO₂(aq) → K₂SO₄(aq) + NiOH₂(s)</h3>
And now, the reaction is balanced
It is like an idea that they come up with in an experimeant

Answer : The equilibrium constant for this reaction is,
Explanation :
The given main chemical reaction is:
;
The intermediate reactions are:
(1) ;
(2) ;
We are reversing reaction 1 and multiplying reaction 2 by 2 and then adding both reaction, we get:
(1) ;
(2) ;
Thus, the equilibrium constant for this reaction will be:
Thus, the equilibrium constant for this reaction is,
