Chapter 12, Problem 10STP

Interpretation Introduction

Interpretation: To state whether statement I and statement II are true or false. To determine if statement II is the correct explanation of statement I.

Concept Introduction: The coefficients are the numbers that are written in front of the chemical formula/symbol in order to balance a chemical reaction. The coefficients help in determining the conversion factors between the number of moles for two different substances in a chemical equation.

Answer to Problem 10STP

Statement I is the incorrect explanation for Statement II.

Explanation of Solution

In a balanced chemical reaction, the ratio between the number of moles of different compounds is defined as a mole ratio. The moles of each element can be calculated by dividing the number of moles each by the smallest number of moles.

The larger number is always written in the numerator in the mole ratio.

Therefore, the given statement (a statement I) is true.

The mole ratio is used to convert the given number of moles of reactants and products to the moles of different reactants or products. The mole ratio can be equal to one or greater than one.

Therefore, statement II is false.

Conclusion

Thus, statement I is the incorrect explanation for Statement II.
