You are given the following naturally occurring amino acids: leucine, and glutamic acid. Glutamic acid contains two carboxylic acid groups. Draw the skeletal structure of all the peptides you can make combining one of each of these amino acids. (Show your products in the unionized state and omit any stereochemistry.)
Rank the following ionic compounds in order of increasing attraction between their ions: BaO, BaCl2, and CaO.
Thermodynamic measurements reveal that ?H° = -66.3 kJ/mol and ?S° = -73.2 J/mole*K at 40°C. What is the equilibrium constant for the binding reaction at 40°C?
Ethylene glycol, HOCH2CH2OH, is effective as an antifreeze, but it also raises the boiling temperature of automobile coolant, which helps prevent loss of coolant when the weather is hot.
A solution is made by dissolving 0.150 moles of benzoic acid (ka=6.5*10^-5) and 0.300 moles of sodium benzoate in enough water to give exactly 1.00 L of solution what is the solution pH

Using electronegativity, predict in the order of decreasing polarity the following bonds: N-P, N-O, N-C, N-S, N-F. Predict how valence electrons would pair up in the AsO4-3 ion.
Buffer solution Problem to determine pH, Determine the pH after the addition of 10.0ml of 0.1M NaOH to 100.00ml of this buffer. An aqueous solution of 100.0ml 0.100M NaCl is titrated with 0.100M AgNO3 (AgCl Ksp= 1.0x10^-10) pAg=-log[Ag+]
The atmospheric sulfur dioxide concentration over a certain region is 0.12 ppm by volume. Calculate the pH of the rainwater due to this pollutant. Assume the dissolution of SO2 does not affect its pressure.
A lab protocol on synthesizing sulfathiazole from p-acetamidobenzenesulfonyl chloride and 2-aminothiazole. It would be appreciated if exact amounts of reagents, solvents, etc (in grams, mmols, mls - etc), could be given.
A solution is prepared by dissolving 0.16mol of acetic acid and 0.16mol of ammonium chloride in enough water to make 1.0 L of solution.
A polluted water sample is suspected of being contaminated with one of the following; soap, ABS Surfactant, or LAS. In soft water, the sample has a very high BOD relative to its TOC.
