Chapter 7: Q. 7.89 (page 254)

If green sphere represents the chlorine atoms and red sphere represents the oxygen atoms and all are gases.

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

Short Answer

Expert verified

(a) The Reactants of reaction are Cl2,O2and Products areCl2O.

(b) The balanced chemical equation is localid="1652885322279" 4Cl2+2O2鈫�4Cl2O.

(c) This is a combination reaction.

Step by step solution

01

Part (a) Step 1: Given Information

We need to find the reactants and products of reaction.

02

Part (a) Step 2: Explanation

We are given that green sphere represents the chlorine atoms and red sphere represents the oxygen atoms .

Therefore,

Reactants of reaction areCl2,O2.

Products of reaction are Cl2O.

03

Part (b) Step 1: Given Information

We need to write the reaction of given molecule.

04

Part (b) Step 2: Explanation

We are given that

Reactants of reaction are Cl2,O2.

Products of reaction isCl2O.

Then balanced chemical equation :

4Cl2+2O2鈫�4Cl2O

05

Part (c) Step 1: Given Information

We need to find the type of reaction.

06

Part (c) Step 2: Explanation

If we are the reaction 4Cl2+2O2鈫�4Cl2O.and we see that two molecules combined and then formed a new compound. so it is Combination reaction.
