HELP! NEED AN ANSWER! ASAP what would have happened to the path of particles in Rutherford’s experiment if he had used a negatively charged particle instead of the positively charged alpha particles?

If the empirical formula of a compound is known what is needed in order to determine the molecular formula a) the coordination numbers b)the molecular geometry c) the molar mass

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?

How can parts of a solution be separated by chromatography?
