Give a flowchart analogous to separating a diethyl ether solution containing anthracene, benzoic acid, 2- naphthol, and 4-nitroaniline. All compounds are solids when pure.
Draw all substitution products for the reaction of 1-iodo-2-methylcyclohexane with methanol (the products should all be ethers).
For a given reaction, the reaction forms predominantly products at equilibrium (i.e. it essentially goes to completion). Which of the following represents a reasonable value for K
Write the net ionic equation to show the formation of a precipitate (insoluble salt) when the following solutions are mixed. Write noreaction if no insoluble salt forms
Glutamine, glycine, aspartic acid, threonine, isoleucine and arginine form a hexapeptide. What would be the overall charge of this peptide at pH 1
Calculate the energy released when a 28.9 gram piece of copper is cooled from its melting point of 1083 degrees C to 25.0 degrees C. The specific heat of copper is .385 J/g degrees C.
How would you distinguish experimentally between an amphourous, a crystalline and a crosslinked polymer
in terms of the structural aspects of hb that we discussed in class explain asmany features of the following hb
Write three orbital designations that would be incorrect and explain why each is incorrect. For example, 1p would be an incorrect orbital designation because there is no p sub-shell in the first orbit.
Calculate the standard reaction enthalpy for the formation of boron trifluoride, which is widely used in the chemical industry:B2O3(s) + 3CaF2(s) > 2BF3(g) + 3CaO(s).
how many grams of copper are produced when excess aluminum reacts with 11.0 g of copper oxide.
