Chapter 5, Problem 5.16UKC

Assume that the mixture of substances in drawing (a) undergoes a reaction. Which of the drawings (b)–(d) represent a product mixture consistent with the law of conservation of mass?

Interpretation Introduction

Interpretation: The correct representation of product mixture consistent with the law of conservation of mass should be determined from the given representations.

Concept introduction:

Law of conservation of mass states that, the number of atoms remains constant throughout the reaction, simply it can be stated as follows, “during a chemical reaction atoms are neither be created nor be destroyed”.

Answer to Problem 5.16UKC

The correct representation of product mixture consistent with the law of conservation of mass is,

Explanation of Solution

Given representation of reaction is,

Law of conservation of mass states that, the number of atoms remains constant throughout the reaction.

In the representation (a) totally 18 spheres are there which representing the reactant molecules, and in the representation of product mixture (d) consistent with the law of conservation of mass, because except the other product mixture representation such as b and c only the representation d has equal number of spheres as in reactant mixture.

Therefore,

The correct representation of product mixture consistent with the law of conservation of mass is,

Conclusion

The correct representation of product mixture consistent with the law of conservation of mass is determined.
