Describe the mechanism of the preparation of 2-methyl-3-hexanol by reducing an appropriate carbonyl compound.
Chromium crystallizes in a body-centered cubic lattice (the Cr atoms are at the lattice points only). If the density of the metal is 7.19 g/cm3, what is the unit cell edge length in pm?
What is the half-life of a compound if 89 percent of a given sample of the compound decomposes in 56 min? Assume first-order kinetics.
Phenol and straight chain alcohol, The compound C6H5OH is a phelol, and C6H13OH is a straight chain alcohol.
The reaction caused the temperature of the solution to rise from 22.06 C to 26.42 C. If the solution has the same density and specific heat as water, what is deltaH for this reaction (per mole of H2O produced)?
a tank with a volume of 1.00M3 is filled with air at 0 degrees to 20 times its atmospheric pressure. How much volume will occupy at 1 atom and room temp?
