if the walls in a room are 955 square feet in area and a gallon of paint covers 15 square yards how many gallons of
We use standard addition methods when our sample has matrix effects which are hard to duplicate in a blank. Let's again find the amount of Pb+2 in a blood sample. A 5.00 mL blood sample containing lead yielded a signal of 0.712 units.
At 50°C the vapor pressure of ethanol is 0.30 atm, acetic acid is 0.08 atm, water is 0.12 atm, and acetone is 0.84 atm. A) Arrange these substances in order of increasing rates of evaporation.
Compute the translational, rotational, vibrational (compute excluding and including the zero point energy term), as well as electronic (compute taking the zero of energy to be that of the ground state molecule as well as that of the separated atom..
A buffer is prepared by adding 1.50X 10^2 ml of 0.250 M NaOH to 2.50X10^2 ml of 0.350 M weak acid, HB. The solution is diluted to 1.00 L. If the pH of the resulting solution is 6.55, what is the pKa of the weak acid
How would one synthesize 1,3-dibromo-2-methoxy-5-nitrobenzene starting with benzene
