A sample of lead has a mass of 14.6 g. A graduated cylinder contains 7.5 ml of water. After the lead sample is dropped into the cylinder, the water level reads 11.9 ml. Calculate the density of the lead

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)
