Carbon monoxide and chlorine gas react to produce phosgene (COCl2) gas according to the following reaction at 100.0°C: CO(g)+Cl2(g)⟺COCl2(g)Kp=1.49×108 In an equilibrium mixture of the three gases, PCO = PCl2 = 4.83 x 10-4 atm, what is the equilibrium partial pressure (in atm) of phosgene?

21. consider the following chemical reaction: n2+ o2 2 no if 10.0 g of n2 reacts with excess oxygen then how many grams of no can be formed? a) 10.7 g b) 21.4 g c) 32.9 g d) 42.8 g page 4 of 8

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.

Which of the following nuclei would be the least stable a 2 protons, 2 neutrons b 1 proton 1 neutron c 1 proton 3 neutrons d 1 proton 2 neutrons
