An aqueous solution of calcium hydroxide is electrolysed using carbon electrodes.
1) what will be liberated at the anode?
2) it was observed that during the electrolysis, the mass of the anode decreased and a white precipitate was formed. explain.

Agas has a volume of 0.7 l at 300 mmhg. what would be the new volume at 900 mmhg

If i initially have a gas at a pressure of 12 atm, a volume of 23 liters, and a temperature of 200 k, and then i raise the pressure to 14 atm and increase the temperature to 300 k, what is the new volume of the gas?

Consider the following reaction at equilibrium. 2co2 (g) 2co (g) + o2 (g) h° = -514 kj le châtelier's principle predicts that the equilibrium partial pressure of co (g) can be maximized by carrying out the reaction a. at high temperature and high pressure b. at high temperature and low pressure c. at low temperature and low pressure d. at low temperature and high pressure e. in the presence of solid carbon
