The chemical equilibrium is given: 2NO (g) + O2(g) <—>2N O2, (g)

In a container of volume 10L is in equilibrium a mixture consisting of 10 mol NO (g), 10 mol O2, (g) and 20 mol NO2, (g).

The volume of the container changes under constant temperature and after the restoration of equilibrium the amount of NO has increased by 25%. Calculate the volume change in L.

How do I find the change in volume?

P. s sorry if my English isn’t perfect.

For ai it's atomic number is 13 and it's mass number is 27 how many neutrons does it have

Salicylic acid is a very important acid. it is used to synthesize the aspirin by treating with acetic anhydride. a 0.2015-g sample of salicylic acid was dissolved in a 100.00-ml volumetric flask, and the solution was diluted to the mark. a 10-ml aliquot of this solution was titrated with standard naoh (0.01130 + 0.2% n) to a phenolphthalein faint pink color end point at 19.81 ml. (a) (calculate the normality of the salicylic acid solution used in the titration. (b) assuming the salicylic acid is pure, what is the equivalent weight of the salicylic acid? practice problems for the final exam (continued) (c) (calculate the inherent error in the determination of the equivalent weight you calculated in part (b). use the following absolute errors in the equipment /glassware when calculating the inherent error. 5.00-ml pipet: + 0.02 ml 100-ml volumetric flask: + 0.08 ml analytical balance: + 0.2 mg 25-ml buret: + 0.03 ml
