Interpretation: The window that represents reaction products should be identified.

Concept Introduction: The mass of reactants is always equal to the mass of products during any chemical reaction. This observation of the equal mass of reactants and products is stated by the law of conservation of mass, which states that mass is conserved in any chemical or physical change.

Expert Solution & Answer

Answer to Problem 10STP

Correct answer: window (B).

Explanation of Solution

Reason for correct option:

The given window for reactants is:

Chemistry 2012 Student Edition (hard Cover) Grade 11, Chapter 2, Problem 10STP , additional homework tip 1

The number of reactants represented by dark color balls are 5 and by light color balls are 6. Using the law of conservation of mass, which states that the mass of reactants is always equal to the mass of products during any chemical reaction the window that represents reaction products will be B. As the total number of balls in window B is 11 that is 5 light color and 6 dark color balls.

Conclusion

Reasons for incorrect options:

In window C and D, the law of conservation of mass is not obeyed as the mass of product formed in window C and D is different from window A. In window C, the number of dark balls increases and that of light balls decreases whereas in window D, the number of dark balls decreases.
