Balance the following equation:
B203(s) + HF(l) => BF3(g) + H20(l)

How many grams of co(g) are there in 74.5 ml of the gas at 0.933 atm and 30o c?

If a solution had a ph of 7 what is the solution

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.
