15. How many moles of electrons is required to deposit 5.6g of iorn from a solution of iron (II) tetraoxosullphate (VI)? [Fe = 56, S = 32, 0 = 16] (a) 0.1 moles (b) 0.2 moles (c) 1.0 moles (d) 2.0 moles.​

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.
