Determine the Kelvin temperature required for 0.0140 mol of gas to fill a balloon to 1.20L under 0.988 atm a pressure.

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.

Which chemical reaction is flawed? (answer ) a. 2ni3 > n2 + 3i2 b. 2h2 + o2 > 2h2o c. caco3 + 2hcl > cacl2 + h2o d. 2albr3 + 3cl2 > 2alcl3 + 3br2
