Chapter 7: Q. 7.87 (page 255)

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.

Short Answer

Expert verified

(a) The Reactants of the reaction isNI3and Products areN2,I2.

(b) The balanced chemical equation islocalid="1652885151735" 2NI3鈫�N2+3I2.

(c) This is a decomposition reaction.

Step by step solution

01

Part (a) Step 1: Given Information

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

02

Part (a) Step 2: Explanation

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

Therefore,

Reactants of reaction is NI3.

Products of reaction are N2,I2.

03

Part (b) Step 1: Given Information

We need to balanced the reaction of given molecules.

04

Part (b) Step 2: Explanation

We are given that

Reactants of reaction isNI3.

Products of reaction are N2,I2.

Therefore,

The balanced chemical reaction is localid="1652885165684" 2NI3鈫�N2+3I2.

05

Part (c) Step 1: Given Information

We need to find the type of reaction.

06

Part (c) Step 2:  Explanation

We have chemical reaction 2NI3鈫�N2+3I2. then compound decomposes into two molecules so it is Decomposition reaction.
