Draw Lewis dot structure and predict molecular geometry - Show the Lewis structures of the following molecules and then predict their geometry.
For the reaction 2A + B --> 2C, if B is initially 4.0M and 2min later is 3.0M, what is the rate of appearance of C?
If 465 mL of oxygen at STP is used in the reaction, what volume of CO2 measured at 37 degrees C and 0.973 atm, is produced?
A 2.52- sample of a compound containing only carbon, hydrogen, nitrogen, oxygen, and sulfur was burned in excess to yield 4.36 of and 0.892 of as the only carbon and hydrogen containing products respectively.
Calculate the initial rate of the NO reduction at 1100 K if 400.00 mg of NO and 600.00 mg of H2 are confined to a 5.00 L reaction vessel.
A chemist wishes to prepare 200mL of a saturated solution of BaF2, the concentration of which is 6.3 x 10-3 mol/L. Determine the mass of BaF2 that will be needed to make up the 200mL of the solution.
