When Lewis and Clark came through this area in the early 1800s they were forced to portage around the "Great Falls of the Missouri". What is the name of the dam that now uses the great falls for hydroelectric power?
A 10.00 mL sample of a solution of hydrofluoric acid,HF, is diluted to 500.00 mL. A 20.00 mL sample of the diluted solution requires 13.51 mL of a 0.1500 M NaOH solution to be titrated to the equivalence point.
What mass of precipitate will form if 1.50L of concentrated Pb(ClO3)2 is mixed with 0.250L of 0.290 M Nal?
what is the density of a piece of metal if it's mass is 201 g and its volume is 18.9 cm3
Methylbenzene and 1,2-dimethylbenzene mix to form an ideal solution. At 90oC, the vapor pressure of pure methylbenzene is 400 Torr and that of pure 1,2-dimethylbenzene is 150 Torr.
How much of the solution is needed?
A solid mixture contains MgCl2 and NaCl. When 0.5000 g of this solid is dissolved in enough water to form 1.000 L of solution, the osmotic pressure at 25°C
