Draw the three dimensional structure of both the endo and exo adduct formed from 1,3-cyclopentadiene and maleic anhydride. which stereoisomer is formed? is this the result of kinetic or thermodynamic control of the reaction
Calculate the total heat in joules needed to convert 25.00 g of ice at -3.50 degrees c to liquid water at 0.250 degrees c.
Illustrate the structures of the 6 bromoalkenes (with the molecular formula C5H9Br ) that have a branched C chain, and that show neither chirality nor E,Z isomerism.
Using a flow diagram, show the separation of a mixture containing p-bromoacetanilide, N-cyclopentyl-N-methyl-N-propylamine (N means the group is attached to the nitrogen of the amine) and m-nitrophenol. Specify the organic solvent and aqueous
A sample of gas occupies 250. mL at 37 degrees celsius and 730. torr; what volume would the gas occupy at standard conditions?
The Ksp of barium carbonate (BaCO3) is 5.0*10^-9 at 25.0 C. If a 20.0 mL sample of 0.1 M Ba(NO3)2 is added to 50.0 mL of 0.1 M Na2CO3.
7.04 g of CuNO3 is dissolved in water to make a 0.300 M solution. What is the volume of the solution.
what are the hydrolysis by-products? What limits the reaction? What determines whether the hydrolysis reaction proceeds from cellulose to sugar (e.g. glucose) or continues on to convert the sugars to alcohol?
What is the final pH of a solution that contains 0.1 M of H2N-CH2-CH2-NH3+ Cl- and 0.01 M of Cl- NH3+-CH2-CH2-NH3+. The pKa values of the compound are as follows; pKa1= 7.5 and pKa2= 9.5:
MgNH4PO4 • 6H2O loses H2O stepwise as it is heated. Between 40º and 60º C the monohydrate (MgNH4PO4 • H2O) is formed and above 100º C the anhydrous material (MgNH4PO4) is formed. What are the phosphorus percentages of the monohydrate and anhydrous..
derive Raoul's law using the chemical potentials of the constituents that make up the mixture of the solution.
Classify the following solutions as saturated, unsaturated, or supersaturated, based on your graph. Note that c. and d. require you to convert from the concentrations give to g/100 g H2O before you refer to the graph.
