What coefficients must be placed in the following blanks so that all atoms are accounted for in the products?
C₆H₁₂O₆ → ________ C₂H₆O + ________ CO₂
A) 2; 1
B) 3; 1
C) 1; 3
D) 2; 2

Question

Quizplus · Accepted Answer

The balanced equation would be:
C₆H₁₂O₆ → 2C₂H₆O + 2CO₂, which means that there are two molecules of ethanol (C₂H₆O) and two molecules of carbon dioxide (CO₂) produced for every molecule of glucose (C₆H₁₂O₆) consumed. Therefore, the coefficients for ethanol and carbon dioxide are both 2. Choice D is the only option with both coefficients as 2.
