The following exercises involve oxides of nitrogen: one kmol of n2o4 dissociates at 25℃, 1 atm to form an equilibrium ideal gas mixture of n2o4 and no2 in which the amount of n2o4 present is 0.8154 kmol. determine the amount of n2o4 that would be present in an equilibrium mixture at 25℃, 0.5 atm. a gaseous mixture consisting 1 kmol of no, 10 kmol of o2, 40 kmol of n2 reacts to form an equilibrium ideal gas mixture of no2, no, o2 at 500k, 0.1 atm. determine the composition of the equilibrium mixture for no+1/2 o_2⇌no_2, k=120 at 500k.

When the volume and number of particles of a gas are constant which of the following is also constant

Nconcentration refers to the molar concentration of an ion in solution. it may be identical to, or greater or less than, the molar concentration of the compound containing the ion that was used to make the solution. for soluble salts, the molarity of a particular ion is equal to the molarity of that compound times the subscript for that ion. for example, 1 m of alcl3 is 1 m in al3+ and 3 m in cl−. 1 m of (nh4)2so4 is 2 m in nh4+ and 1 m in so42−. part a what is the concentration of k+ in 0.15 m of k2s? view available hint(s) nothing m m part b if cacl2 is dissolved in water, what can be said about the concentration of the ca2+ ion? view available hint(s) if is dissolved in water, what can be said about the concentration of the ion? it has the same concentration as the cl− ion. its concentration is half that of the cl− ion. its concentration is twice that of the cl− ion. its concentration is one-third that of the cl− ion. part c a scientist wants to make a solution of tribasic sodium phosphate, na3po4, for a laboratory experiment. how many grams of na3po4 will be needed to produce 550 ml of a solution that has a concentration of na+ ions of 0.700 m ? express your answer numerically in grams. view available hint(s) mass of na3po4 n a 3 p o 4 = nothing g provide feedback
