The rate determining step for the destruction of ozone is the formation of the Clo dimer (formula: CloOCI) shown in the equation below. The rate is second order to the concentration of Clo. ClO+ CIO ooc (kaea3.4x1012 molecule cm s) This reaction is followed by the fast photolysis of the dimer and the fast destruction of ozone by Cl atoms: CLOOC+hy 2 CI+O Given the following concentrations: [CIO] 9.8 x 10 molecule cm and initial O, concentration 1 x 10...

2. If the mass of a proton is taken as 1.60 x 10-27 kg and the radius as 1.50 x 10-13 cm, approximately how much would one cubic centimeter (about a thimble-full) of solid nuclear matter weigh? Ignoring the 'gaps' between the spheres simply find the density of a single proton in kg/cm3 and then convert your answer to Tons/cm3, using the conversions that 1 kg weighs 2.20 pounds, 1 Ton equals 2000 pounds.
