The analysis on a mass basis of an ideal gas mixture at 30°f, 15 lbf/in.2 is 25% co2, 30% co, and 45% o2.
determine:
(a) the analysis in terms of mole fractions.
(b) the apparent molecular weight of the mixture.
(c) the partial pressure of each component, in lbf/in.2
(d) the volume occupied by 10 lb of the mixture, in ft3.

c is the answer because when something is left after something evaporates that shows the chemical change.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
