A sample of oxygen, at 25°C, occupies a volume of 5.56 × 102 milliliters (mL) at 1.60 atm pressure. What pressure must be applied to compress the gas to a volume of 1.90 × 102 mL, with no temperature change?

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

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.

In an exothermic reaction at equilibrium, what is the effect of lowering the temperature? a. the reaction makes more products. b. the reaction makes more reactants. c. the reaction is unchanged.
