Major Monogram sent Agent P to a different mission. Agent P will be out of reach for a time. Major Monogram thinks that he can handle Agent P's laboratory when he encountered a problem. The pressure of hydrogen fluoride in Agent P's lab is lower than expected and rises more quickly as the temperature is increased than the ideal gas law predicts. Suggest an explanation. Are we dealing with a real or ideal gas?
The ground water in Pherric, New Mexico contains 1.80 mg/L of iron as Fe+3. What pH is required to precipitate all but 0.30 mg/L of the iron as Fe(OH)3 at 25oC?
what is the charge on magnesium iodide? what does the charge on the magnesium ion have to do with the number of valence
Calculate the difference between its molar Gibbs energy and that of an ideal gas in the same state.
Indicate the approximate location (cm-1) in the IR Spectrum where you would expect to see one or two absorptions that distinguish the compounds in Diethyl Ether.
You decide to use gel filtration. This works brilliantly and you determine that your protein is 80kDa at the same time. But wait! The gene that corresponds to HMD predicts a protein of only 38kDa. What are two potential causes of this discrepancy?
Calculate the five points indicated in the experiment introduction and show these values in a small table along with one sample calculation.
Acetylene gas (C2H2) is produced as a result of the following reavtion. CaC2(s) + 2H2O(l) yield C2H2(g) +Ca(OH)2(aq)
A solution is initially 2.5 x 10-3 M in Cu+ and 2.5 x 10-3 in Pb 2+. Iodine ion is gradually added to the solution. Determine the concentrations of Cu+, Pb +2, and I- at the point of maximum separation. The solubility products of CuI and PbI2 are ..
How many moles of HCl must be added to 1.0 L of 1.0 M NH3(aq) to make a buffer with a pH of 9.00? (pKa of NH4^+ = 9.25)
Celsius and -125 degrees Celsius , respectively. Calculate the entropy changes for fusion ( solid to liquid) and vaporization (liquid to gas ).
A weak acid (HA) has a pKa of 4.999. If a solution of this acid has a pH of 4.459, what percentage of the acid is not ionized
If 2 new elements have been discovered and one is R, a new element from the family with 3 valence electrons and Z, a new element from the family with 6 valence electrons. Write the formula for the binary compound between element R and element Z.
