Suppose we add 1 g of solid ice at 0 degrees celsius to 4 g of liquid water at 10 degrees celsius and the system reequilibrates at 0 degrees celsius.
a) Calculate how much water must melt in order to reach exactly 0 degrees celsius at thermal equilibrium.
b) Calculate the entropy changes for ice, liquid water and the total entropy change.
c) Is this process spontaneous?
Calculate how many grams of ATP must be produced to walk a mile. ATP synthesis is coupled to the oxidation of glucose (?Go' = -686 kcal/mol). How many grams of glucose are actually metabolized to produce this amount of ATP?
Explain how mass effects act to lower the carbonyl frequency, as well as how inductive and hyperconjugation effects act to raise the carbonyl frequency
If a 1000 kilogram sample of rock is 0.021% gold by mass, how much zinc is needed to react with the gold extracted from the rock? Assume that the reaction is 100% efficient.
The surface area of 100 g of glucose > than that of 1 g. give explanation why the solubility does not increase with the amount of solid deposited at the bottom of the flask?
At 25 oC, experiment shows that the total pressure of the gases in equilibrium with the solid is 0.116 atm. What is the equilibrium constant Kp and Kc?
Calculate the temperature of the system once equilibrium has been reached. Assume that Cp,m for Au and H2O is constant at its value for 298K throughout the temperature range of interest.
When a sample of PCl5(g) (0.1612 mol/L) is placed in 35.00 L reaction vessel at 878.0 K and allowed to come to equilibrium the mixture contains 3.122 mol of PCl3(g)
Based on the functional group(s) present in the two compounds, determine 3 physical properties for each of the two compounds. Using these physical properties determine how each of the two compounds uniquely function in the products in which they ar..
The mysterious peptide X is a nonapeptide that cannot be sequenced by Edman degradation. However, it is susceptible to cleavage by proteases, and the resulting peptide fragments can be sequenced.
Calculate the number of moles of quicklime, CaO, that would be produced by the decomposition of 30.0 moles of limestone, CaCO3, in the following reaction.
constitutionally isomeric ketones that have the molecular formula C4H8O2
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.
