Why do chemists count matter using moles? a) because a dozen was already taken
b) because atoms and molecules are too small to count one-by-one
c) because a mole represents a number small enough to count matter.
d) because chemists are lazy

Which actions would increase the rate at salt dissolves in water? stir the water? crush the salt? use less water? heat the water? cool the salt

Fill in the coefficients that will balance the following reaction: a0cr2(so4)3 + a1agno3

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?
