Given the atomic radius of radon, 1.5 Å, and knowing that a sphere has a volume of 47m3/3, calculate the fraction of space that Rn atoms occupy in a sample of radon at STP.

Layers of rock containing fossils, like the layers illustrated here, are most likely composed of rocks.

Consider the reaction: n2(g) + o2(g) ? 2no(g) kc = 0.10 at 2000oc starting with initial concentrations of 0.040 mol/l of n2 and 0.040 mol/l of o2, calculate the equilibrium concentration of no in mol/l how would this be done?
