Answer: 2

Explanation: Potassium, K, has only 1 valence electron, 4s^1.  Oxygen, O, needs 2 more electrons to complete its valence shell to make 8 electrons.  That means 2 K atoms will combine with 1 O atom, to produce K2O, potassium oxide.  Both K electrons are stolen by the single O atom, so 2 electrons are transferred.

Smaller container means less volume, and the molecules will hit the walls of the container more frequently because there's less space available and the pressure will go up. I guess this would mean that the side with fewer moles would be favored as a result. We count the number of moles on the reactants and products and find that there are fewer moles on the product side, so I guess this would favor the product formation.
