Chapter 8, Problem 35UTC

The chapter sections to review are shown in parentheses at the end of each problem.

Balance each of the following by adding coefficients, and identify the type of reaction for each: (8.1, 8.2, 8.3)

Chapter 8, Problem 35UTC, The chapter sections to review are shown in parentheses at the end of each problem. Balance each of

(a)

Expert Solution
Check Mark
Interpretation Introduction

Interpretation:

The given reaction should be balanced by adding appropriate coefficients; in addition the type of the reaction needs to be identified.

Concept Introduction:

  • Chemical reactions can broadly be classified into 5 types based on how the reactants interact to form products, these include: combination reaction, decomposition reaction, single replacement, double replacement and combustion reaction.
  • A chemical reaction is said to be balanced if there are equal number of atoms of one kind in the reactants and products

Answer to Problem 35UTC

If blue spheres = A, red spheres = B, then the balanced equation is:

AA + BB2BA

This is a combination reaction

Explanation of Solution

In the given reaction, two molecules combine to form a single product. This is representative of a combination reaction.

Let the blue spheres be represented by the element ‘A’ and the red by element ‘B’. The given unbalanced reaction is therefore,

AA + BBBA

The equation is not balanced since the number of A and B atoms in the reactants are 2 while there are only 1 each on the product side. In order to balance the equation, multiply BA by 2 to get:

AA + BB2BA

Answer to Problem 35UTC

If blue spheres = A, red spheres = B, then the balanced equation is:

2ABA2AA + BB

This is a decomposition reaction

Explanation of Solution

In the given reaction, a single reactant splits to form two simpler compounds. This is representative of a decomposition reaction.

Let the blue spheres be represented by the element ‘A’ and the red by element ‘B’. The given unbalanced reaction is therefore,

ABAAA + BB

The equation is not balanced since the number of A and B atoms in the reactants are 2 and 1 respectively while in the product side they are 2 each. In order to balance the equation, multiply ABA by 2 and AA by 2 to get:

2ABA2AA + BB
