5. Assign oxidation numbers to substances in the three-step production of sulfuric acid to show which reactions are redox and which are not.
S (s) + O2 (g) – SO2 (g)
SO2 (g) + O2 (g) – SO3 (g)
SO3 (g) + H2O (1) - H2SO4 (1)

Hey guys so i need to know what is _nh3+> nh4oh ~chemistry~

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?
