Answer to Question #96901 in General Chemistry for Shehnaz Chaudhri

Question

The reaction be te when C6H12O6 and O2 is represented by the balanced equation below. In an experiment, 0.30 miles of CO2 was produced from the reaction of 0.05 mole of C6H12O6 with excess O2. The reaction was repeated at the same temperature and in the same container, but this time 0.60 mole of CO2 was produced. Which of the following must be true and the other choices not true?

C6H12O6+6O2 yields 6CO2 + 6H20

A. The initial amount of C6H12O6 + 6O2 in the container must have been 0.10 mole.
B. Exactly 0.3 mole of C6H12O6 must have reacted because C atoms were conserved.
C. Exactly 0.4 mole of O2 must have reacted because the temperature and container volume are the same.
D. More than 0.6 mole of O2 must have reacted because it was present in excess.

Answer 1

All the statement $A,B,C\ and\ D$ are false

Because 0.10 moles of $C_6H_{12}O_6$ will react with 0.6 moles of $O_2$
