Answer to Question #210622 in General Chemistry for Lumina

Question

C6H12O6(s)+6O2(g)=6H2O(g) + 6 CO2 (g)

1. What happens to the concentrations of :

a . C6H12O6 and the reaction proceeds ?

b . H2O + CO2 as the reaction proceeds?

2. According to the collision theory , what 3 circumstances are needed for C6H12O6 & O2 to react?

Answer 1

Divide 8.064 g of glucose by its molar mass to get moles glucose.Multiply times the mol ratio 6 mol H2 from the balanced equation to get moles water.Multiply times the molar mass of H2O to get mass of water.

8.064g C6H12O6×1mol C6H12O6

180.15588g C6H12O6×6mol H2O1molC6H12O6×18.01528g H2O1mol H2O

=4.838 g H2O
