Here is it, Bromine is less electronegative than chlorine, yet methyl bromide and methyl chloride have very similar dipole moments. Why?
Assume the electron distribution would go more towards the methyl group as the bond is larger and larger, resulting in a higher dipole moment for the Chlorine. I'm super confused with this concept.
If 0.80 g of a gas occupies 295 mL at 25C and 680 mm Hg of pressure what is the molar mass of the gas?
Calculate the mass of HONH2 required to dissolve in enough water to make 250.0 ml of solution having a pHof 10.00 (Kb=1.1*10 (-8).

For the 3 wood preservatives noted, would acidic vs. alkaline soil or water conditions cause more (or less) leaching or dissolution of these compounds. How do these compounds actually leach out of wood into the environment?
Caffeine, C8H10N4O2, is a stimulant found in tea and coffee. A sample of the substance was dissolved in 41.5 g of chloroform, CHCl3, to give a 0.0940 m solution.
