If one starts with pure NO 2 (g) at a pressure of 0.500 atm, the total pressure inside the reaction vessel when 2NO 2 (g) 2NO(g) O 2 (g) reaches equilibrium is 0.674 atm. What is the equilibrium partial pressure of NO 2

If you add 10ml of hot water to 10ml of cold water and the change in tempature 8°c calculate how much energy is gained by the cold water

In a ni-cd battery, a fully charged cell is composed of nickelic hydroxide. nickel is an element that has multiple oxidation states. assume the following proportions of the states: nickel charge proportions found 0 0.17 +2 0.3 +3 0.33 +4 0.5 (a) determine the mean of the nickel charge. enter the answer to 2 decimal places.(b) determine the cumulative distribution function of nickel charge.

Who discovered a pattern to the elements in 1869?
