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
Answer to Problem 6STP
Statement I is the correct explanation for Statement II.
Explanation of Solution
For a balanced chemical equation, coefficients are important and conversion factors between the number of moles for two different substances in a chemical equation.
Thus, all stoichiometric calculations use a balanced chemical equation.
Therefore, the given statement (a statement I) is true.
The law of conversation of mass states that mass can neither be created nor destroyed. In a chemical reaction, the mass remains conserved.
Therefore, statement II is true.
Thus, the statement I is the correct explanation for Statement II.
