What mass of aluminum chloride (MM AICI3 = 133 g/mol)
added to 25.0 g of water raises the boiling point of water by
9.58 K? (Kb of water = 0.512 K. kg/mol)

Butadiene undergoes a reaction at a certain temperature in the gas phase as follows: 2c4h6(g) --> c8h12(g) the following data were collected for this reaction: time (min) [c4h6] (m) 0 0.36 15 0.30 30 0.25 48 0.19 75 0. determine the order of the reaction and the rate constant. 1st order and k = 4.3x10 -4 s-1 1st order and k = 2.3x10-4 s-1 2nd order and k = 4.3x10-4 s-1 2nd order and k = 2.3x10-4 s-1 zero and k = 4.3x10-4 s-1

Compare and contrast the bohr model and the electron cloud models of the atom.
