Question
Chapter 20, Problem 1RQ
To determine
The purpose of coefficients in a chemical equation.
Expert Solution & Answer
Answer to Problem 1RQ
The coefficient is the numeral value showing the amount of reactant and the product species present in a chemical equation.
Explanation of Solution
The chemical equation describes the conversion of reactant species to the product species taking place in a
The exact number of reactant molecules participating and the exact number of product molecules formed in the chemical equation can be depicted by using the numbers with the molecular formula. These numbers are called coefficients.
Coefficients show the respective amount of each reactant and product molecules present in the chemical equation. Coefficients either describe the number of moles or the number of molecules of a participating species in a chemical equation. If in case the coefficient is not mentioned with the respective species in a chemical equation, it is assumed to be a unity that is 1.
Conclusion:
Therefore, the coefficient is the numeral value showing the amount of reactant and the product species present in a chemical equation.

- Suppose there are two transformers between your house and the high-voltage transmission line that distributes the power. In addition, assume your house is the only one using electric power. At a substation the primary of a step-down transformer (turns ratio = 1:23) receives the voltage from the high-voltage transmission line. Because of your usage, a current of 51.1 mA exists in the primary of the transformer. The secondary is connected to the primary of another step-down transformer (turns ratio = 1:36) somewhere near your house, perhaps up on a telephone pole. The secondary of this transformer delivers a 240-V emf to your house. How much power is your house using?
