Q. 7.83 - An Introduction to General, Organic, and Biological Chemistry

Question

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

Step-by-Step Solution

Answer

(a) The balanced chemical equation is $A_2+B_2 \to 2AB$ and this is a addition reaction .

(b) The balanced chemical equation is  ${\mathrm{A}}_2\mathrm{B} \to {\mathrm{A}}_2+\frac{1}{2}{\mathrm{B}}_2$ and this is a decomposition reaction.

Part (a) Step 1: Given Information

We need to find the type of reaction and balanced with coefficients the reactions are given molecules.

Part (a) Step 2: Explanation

We have to given reaction in which two different molecules combined and formed a new molecule .

Therefore,

First reaction is Addition reaction and the balanced chemical equation is :

$A_2+B_2 \to 2AB$

Part (b) Step 1: Given Information

We need to find the type of reaction and balanced the reaction.

Part (b) Step 2: Explanation

In reaction we see there a molecule decomposes in two different  molecules That's why Second Reaction is decomposition reaction and the balanced chemical  equation is :

$A_{2}B \to A_2+\frac{1}{2}{B}_2$
