A gas pressure of 2.0 atm is in a closed container. Indicate the changes in its volume when the pressure undergoes the following changes at constant temperature: a) the pressure increases to 6.0 atm. b) the pressure drops to 1.0 atm. c) the pressure drops to 0.40 atm.

7. what temperature is need to just dissolve 50 g of nh4cl in 75 g of water? '

In the space, show a correct numerical setup for calculating the number of moles of co2 present in 11 grams of co2

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.
