a chemist determines that 6.25 g of iron reacts with 3.45 g of oxygen to form rust. what is the percent composition of each element in the new compound?​

Consider the reaction of a(g) + b(g) + c(g) => d(g) for which the following data were obtained: experiment initial [a], mol/l initial [b], mol/l initial [c], mol/l initial rate, mol/l.s 1 0.0500 0.0500 0.0100 6.25 x 10^-3 2 0.100 0.0500 0.0100 2.50 x 10^-2 3 0.100 0.100 0.0100 1.00 x 10^-1 4 0.0500 0.0500 0.0200 6.25 x 10^-3 what is the rate law for the reaction?

Which compound should undergo substitution of the bromine by phenolate anion? draw the structure of the organic product?
