Suppose that 0.2553 moles of KMnO4 were required to exactly titrate the Fe2+ in a sample. How many moles of Fe2+ were in the sample?
A low-melting solid A was isolated, which combustion analysis showed had composition C9H10O. The substance gave a precipitate when treated with 2,4-dinitrophenylhydrazine solution.
A sample of air contains 78.08% nitrogen, 20.94% oxygen, 0.05% carbon dioxide, and 0.930% argon by volume. How many molecules of each gas are present in 1.00 L of the sample at 31 degrees C and 1.00 atm?
The concentration of alkaline phosphate in the stock solution used in the experiment was .25mg protein/mL. Calculate the activity of the enzyme at Vmax as umole substrate hydrolyzed per minute per mg of enzyme protein.
The observed rate constant(k-observed) for one of the trials was measured to be 0.00400 s^-1. If the concentration of hypochlorite was fixed at 0.134 M, calculate the specific rate constant (k) for the trail.
how much tris (MW 121 g/mol) do you need to make 100 mL of a 20 mM buffer? 2) how much NaCl do you need to make 100 mL of a 5mM solution?
They will dilute the 0.5 M solution to obtain 100 mL of 0.15M solution and dilute the 0.5m solution to obtain 10,000 ppm per mass. What is the molarity, molality, mass fraction and mole fraction
Compute the amount of heat evolved in the oxidation of 32.0 grams of Fe at the temperature 25 oC and pressure 1 atm pressure ( ΔHfo(Fe 2 O 3 ,s) = -824kJ/mol)
Vitamin b6 is needed in the metabolism of amino acids. When it binds to an enzyme it forms a complex with the e-amino group of lysine, which is a primary amine.
for which Kp=2.00 at 20 C. A mixture of NO(g) at a partial pressure of 1.50 atm and NO2(g) at a partial pressure of 0.50 atm is allowed to come to equilibrium in a sealed container maintained at 20 C.
what percentage of the water will be vapor when the system reaches equilibrium? assume ideal behavior of water vapor and that the volume of liquid water is negligible. the vapor pressure of water 35 degree celcius is 187.5 mmHg.
Bradykinin is a nonapeptide that is responsible for the severe pain most people feel after being stung by a wasp. Amino acid analysis of bradykinin gave the following composition of amino acids:
What's the volume of pure hydrogen present in a sample of 55.0 mL of gas saturated with water vapour at 27 °C, if the total pressure is 104.8 kPa?
