One alternate acid base theory states that an base is
A. an OH–1 acceptor
B. an H+1 acceptor
C. an H+1 donor
D. an H3O +1 donor

If anyone would be able to me out with these three questions it would be these are from the chem 2202 course.

Which of these is a physical property

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.
