You start with 100.0 mL of a 0.2500 M solution of NaCl sitting in a beaker. After several days you test the solution and find that it is now 0.3125 M. How much water must have evaporated?
Draw the Lewis Structure and make a rough three-dimensional sketch of each species.
what is the volume of 1 mole of Helium gas when the pressure is 1.47 atm and the temperature is 287 K.
Draw the molecular orbital diagram for CO. Based on your diagram, why does CO always bond through the carbon and not the oxygen atom?
Determine which enantiomer of 2-iodo-3-phenylbutene gives the E product (2R, 3R or 2S, 3R), and explain clearly (using unambiguous diagrams) why that is the case.
0.80g of hydrogen chloride is dissolved in water to make 2.5L of solution. What is the pH of the resulting hydrochloric acid solution?
If aqueous acetone (80% acetone, 20% h2o) is used as the extraction solvent instead of 100% acetone, the extraction yields of chlorophyll a and beta carotene
Sodium atoms emit light with a wavelength of 330 nm when an electron moves from a 4 p orbital to a 3 s orbital. What is the energy difference between the orbitals in kilojoules per mole?
