Describe the differences in the shapes of the electron density distributions for NH3, NCl3, and PF3. Explain how the energy minimized bond angles are consistent with these shapes.
The addition of H2 to double bonds is an important reaction used in the preparation of margarine from vegetable oils. If 50.0 mL of H2 and 50.0 mL of ethylene (C2H4)are allowed to react at 1.5 atm, the product ethane (C2H6) has a volume of 50.0 mL..
(the freezing point constant is 1.86 C/m). On the basis of these data, one can conclude that the nonelectrolyte has a molecular weight of?
How many grams of sodium phosphate will be needed to produce 500ml of a solution that has a concentration of Na+ ions of 1.10M ?
Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons.
Find the molality of the solution. Find the molecular weight of the unknown compound please show steps
Be sure to fully explain how your experiment and the resulting data would allow you to determine the wavelength of maximum absorbance for the FeSCN2+ complex.
If a customer replaces a 85 watt bulb with an 20 watt compact fluorescent bulb that lasts 5000 hours, how much less coal (lbs)will be used to generate the electricity that is saved?
