If the freezing point of the solution had been incorrectly read 0.3 degrees lower than the true freezing pont, would the calculated molar mass of the solute be too high or too low? Explain.
Calculate the number of ATPs generated from the metabolic oxidation of the four carbons of acetoacetyl-CoA to CO2. Now consider the homolog derived from oxidation of an odd numbered carbon chain
draw a lewis structure of the molecule and indicate the number of bonds and orbitals used in bonding. Show electron configurations of the central bonding atom in both the unhybridized and hybridized states.
