Question

Balance each of the following by adding coefficients, and identify the type of reaction for each

Short answer

(a) The balanced chemical equation is $AB+CD\to AC+BD$Substitution reaction.

(b) The balanced chemical equation is $A_2+B\to A_{2}B$Addition reaction.

Step-by-step solution

Part (a) Step 1 : Given Information

We need to balanced the reaction given in figures and also identify the type of reaction.

Part (a) Step 2: Explanation

We are given reaction in which two molecules react with each other and displace anion from each Other Therefore,

First reaction is Substitution reaction and chemical equation are:

$AB+CD\to AC+BD$

Part (b) Step 1: Given Information

We need to balanced the reaction given in figures and also identify the type of reaction.

Part (b) Step 2: Explanation

In Second reaction we see that two different molecules combined with each other and formed a New compound that's why Second reaction is addition reaction and chemical equation are:

$A_2+4B\to 2A{B}_2$
