KMnO4 solutions are magenta/purple in color, with the depth of the color dependingon the concentration (very concentrated solutions may look almost black.) Based onyour data for the wavelengths absorbed by the solution, explain why it is purple. Careful!Remember that the process responsible for the color of the solution isdifferent from the process that is responsible for the colors of the gas discharge tubesand flames tests.

Hydrogenation reactions, in which h2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. in the simplest case, ethene (c2h4) and h2 form ethane (c2h6). if 140 kj is given off per mole of c2h4 reacting, how much heat (in mj) is released when 12 kg of c2h6 forms?

Some molecular compounds, such as hcl, ionize completely in solution. for molecular compounds such as h2co3, most molecules do not ionize in solution. which describes the properties of these two solutes? a. hcl and h2co3 have the same effect on the properties of the solution. b. hcl raises the freezing point of water more than h2co3 does. c. hcl raises the boiling point of water more than h2co3 does.
