Chapter 7: Q. 7.84 (page 254)

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

Short Answer

Expert verified

(a) The balanced chemical equation is AB+CD鈫�AC+BDSubstitution reaction.

(b) The balanced chemical equation is A2+B鈫�A2BAddition reaction.

Step by step solution

01

Part (a) Step 1 : Given Information

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

02

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鈫�AC+BD

03

Part (b) Step 1: Given Information

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

04

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:

A2+4B鈫�2AB2
