A 1.00L flash was filled with 2.00mol gaseous SO2 and 2.00 mol gaseous NO2 and heated. After equilibrium was reached, it was found that 1.30 mol gaseous NO was present. The reaction is:

SO2(g) + NO2(g) <---> SO3(g) + NO(g)

Calculate the value of the equilibrium constant, K, for this reaction.

I thought perhaps it was some sort of RICE equation, and while it is easy to find the molatiry of the two reactants and NO(g) compouds, I cannot figure how to find the molarity of SO3 to calculate the constant. I also just thought that maybe, due to the reactants being equal, at equilibrum so would the products, thus making the molarity of SO3(g) 1.3, but I am not getting the answer my book provides, which is stated to be K=3.4.

Which piece of equipment would me most useful for measuring the volume of some water? a. pan balance b. graduated cylinder c. tweezers d. flask quick

The image compares the arrangement of electrons in two different neutral atoms. a figure labeled atom q has a shaded sphere at the center of three concentric circles. the innermost circle has two black spheres. the middle circle has six black spheres. to the left of this figure is another figure labeled atom p. atom p has a shaded sphere at the center of three concentric circles. the innermost circle has two black spheres. the middle circle has seven black spheres. which of the following best explains the position of the two atoms in the periodic table? atom p has an estimated zeff of 7 and is therefore to the left of atom q, which has a zeff of 6. atom p has an estimated zeff of 7 and is therefore to the right of atom q, which has a zeff of 6. atom p has an estimated zeff of 5 and is therefore below atom q, which has a zeff of 4. atom p has an estimated zeff of 5 and is therefore above atom q, which has a zeff of 4.
