Q. 7.87 - An Introduction to General, Organic, and Biological Chemistry

Question

If blue spheres represent nitrogen atoms, purple spheres represent iodine atoms and the reacting molecules are solid, while the products are gases.

1. Write the formula for each of the reactants and products.
2. Write a balanced equation for the reaction.
3. Indicate the type of reaction as combination, decomposition, single replacement, double replacement, or combustion.

Step-by-Step Solution

Answer

(a) The Reactants of the reaction is$N{I}_3$ and  Products are$N_2,I_2$.

(b) The balanced chemical equation is $2N{I}_3 \to N_2+3I_2$.

(c) This is a decomposition reaction.

Part (a) Step 1: Given Information

We need to find the reactants and products of reaction of given figure.

Part (a) Step 2: Explanation

We are given that  blue spheres represent nitrogen atoms, purple spheres represent iodine atoms .

Therefore,

Reactants of reaction is $N{I}_3$.

Products of reaction are $N_2,I_2$.

Part (b) Step 1: Given Information

We need to balanced the reaction of given molecules.

Part (b) Step 2: Explanation

We are given that 

Reactants of reaction is $N{I}_3$ .

Products of reaction are  $N_2,I_2$.

Therefore,

The balanced chemical  reaction is $2N{I}_3 \to N_2+3I_2$.

Part (c) Step 1: Given Information

We need to find the type of reaction.

Part (c) Step 2: Explanation

We have chemical  reaction $2N{I}_3 \to N_2+3I_2$. then  compound decomposes into two molecules so it is Decomposition reaction.
