What observed rotation is expected when 1.26M solution of (R)-2-butanol is mixed with an equal volume of a 0.630 M solution of racemic 2-butanol, and the resulting solution is analyzed in a sampling container that is 1 dm long? The specific rotation of (R)-2-butanolis -13.9 degrees mL g^(-1) dm^(-1).
List these compounds in order of increasing molar solubility in water show your calculations.
Calculate the biological standard Gibbs energies of reactions of the following reactions and half-reactions
Calculate the pH of each of the following solutions. (a) 0.100 M propanoic acid (HC3H5O2, Ka = 1.3 x 10^-5) (b) 0.100 M sodium propanoate (NaC3H5O2) (c) pure H2O (d) 0.100 M HC3H5O2 and 0.100 M NaC3H5O2
A metal, M, was converted to the chloride, MCl2. Then a solution of the chloride was treated with silver nitrate to give silver chloride crystals, which were filtered from the solution
calculate the temperature of the solution after the CaCl2 dissolves. (Assume no heat is lost to the container or the surroundings and the specific heat of the solution is the same as that of water.)
The radioactive decay of radon follows first-order kinetics and has a half-life of 3.823 days. How many grams of radon will remain after 12.00 days if the sample initially had a mass of 455 g?
Reactions with the following values of ^H and ^S are spontaneous or nonspontaneous and whether they are exothermic or endothermic:
