Dissociation of N204 Q1

One mole of N204 is introduced into a constant pressure chamber at a temperature of 298.15 K

and a pressure of 0.1 bar.

Q1.1

Calculate the fraction of dissociation (a) of N204 (to 2NO2 (9)] when the reaction reaches

equilibrium under these conditions.

Q1.2

Calculate Aran G for the reaction at values of the extent of reaction a of 0.1, 0.4.0.6, and 0.9

moles. (Note -- the reaction is not at equilibrium at these extents of reaction)

What is driving behind plate tectonics (plate movment)? a) gravity only b) inertia c) convection and gravity d) the sun theres no option for science so i picked chemistry. plz

Which form of relativism states that people rely on their own standards of right and wrong when making a decision?

Astudent is given a sample of a blue copper sulfate hydrate. he weighs the sample in a dry covered porcelain crucible and got a mass of 23.875 g for the crucible, lid, and sample. the mass of the empty crucible and lid was found earlier to be 22.652 g. he then heats the crucible to expel the water of hydration, keeping the crucible at red heat for 10 minutes with the lid slightly ajar. on colling, he finds the mass of crucible, lid, and contents to be 23.403 g. the sample was changed in the process to very light clue anhydrous cuso4. if there are again 100.0 g of hydrate, how many grams of cuso4 are in it? how many moles of cuso4? (hint: molar mass of cuso4 = 159.6 g / mole. what per cent of the hydrate is cuso4? you may convert the mass of cuso4 to moles.)
