Complete and balance each of the following equations. If no reaction occurs, enter NOREACTION.
Tatiana [17]

Answer

Part A:

Given equation:

KI_{(aq)}+BaS_{(aq)}\rightarrow

The above equation is an example of a double replacement reaction. A double replacement (or double displacement) reaction is a reaction in which the positive and negative ions of two ionic compounds exchange.

Note: The oxidation number of:

K = +1

I = -1

Ba = +2

S = -2

So, the complete chemical equation including phases of the given reaction is:

2KI_{(aq)}+BaS_{(aq)}\rightarrow BaI_{2(aq)}+K_2S_{(s)}

Part B:

Given equation:

KCl_{(aq)}+CaS_{(aq)}\rightarrow

Also, the equation is an example of a double replacement reaction.

Note: The oxidation number of:

K = +1

Cl = -1

Ca = +2

S = -2

The complete chemical equation including phases of the given reaction is:

2KCl_{(aq)}+CaS_{(aq)}\rightarrow K_2S_{(s)}+CaCl_{2(aq)}
