A solid piece of lead has a mass of 36.24 g and a volume of 3.22 cm3. From these data, calculate the density of lead in SI units (kilograms per cubic meter).

Consider the following multistep reaction: a b→ab(slow) a ab→a2b(fast)−−−−−−−−−−−−−−−−− 2a b→a2b(overall) based on this mechanism, determine the rate law for the overall reaction. express your answer in standard masteringchemistry format. for example, if the rate law is k[a]3[b]2 type k*[a]^3*[b]^2
