Complete the following equations (note that the equations are not balanced). Use the activity series if necessary. An activity s
umka21 [38]

The equation which we are required to complete can be completed as follows;

  • AgNO3 + KCl ==> KNO3 + AgCl

<h3>Electrochemical series;</h3>

Most substitution reactions involve displacement of metals and non-metals.

The possibility of a substitution reaction to occur is sometimes dependent on the order of preference of the metals in the activity series.

On this note, In the reaction between AgNO3 and KCl, potassium, K displaces silver, Ag and the products of the reaction are; KNO3 and AgCl

Look at the four chemical reactions.
frutty [35]

Reaction 3 is different from the rest and it is because a single product is synthesized.

Option 2

<u>Explanation:</u>

The reaction given in 1,2 and 4 are dissociation reaction where a single compound is getting split into two compounds. So all those three reactions are exothermic as they are breaking the bonds leading to release of energy to the surrounding. But the reaction 3 is a formation reaction, where two chemical compounds are forming a single compound.

So in this case, new bonds are formed leading to absorption of energy from the surrounding. So this is an endothermic reaction. Thus, reaction 3 is different from the rest and it is because a single product is synthesized.
