Given the reaction: 4Al + 3O2= 2AL2O3 How many moles of aluminum oxide, Al2O3, can you produce if you have 2 moles of Al

Nitrogen dioxide decomposes according to the reaction 2 no2(g) ⇌ 2 no(g) + o2(g) where kp = 4.48 × 10−13 at a certain temperature. if 0.70 atm of no2 is added to a container and allowed to come to equilibrium, what are the equilibrium partial pressures of no(g) and o2(g)
