How many moles of O2 are required to react completely with 3.2 moles of C2H6?

3.5 moles of O2
6.5 moles of O2
10.4 moles of O2
11.2 moles of O2

Which describes interactions between substances and stomata during photosynthesis? check all that apply. oxygen enters stomata. oxygen is released through stomata. carbon dioxide enters stomata. carbon dioxide is released through stomata. hydrogen enters stomata. hydrogen is released through stomata.

Aroom with dimensions 7.00m×8.00m×2.50m is to be filled with pure oxygen at 22.0∘c and 1.00 atm. the molar mass of oxygen is 32.0 g/mol. how many moles noxygen of oxygen are required to fill the room? what is the mass moxygen of this oxygen?

Answer explain why it is not possible to deduce a complete order of reactivity.
