Give an overview of how macromolecules are synthesized from their monomer components.
Choose an example from each class of macromolecule and describe how it is synthetized.
Long answer required (~200 words).
Assume that gasoline is burned with 99% efficiency in a car engine, with 1% remaining unburned in the exhaust gases as VOCs. If the engine exhausts 16 kg of gases (MW = 30) for each kg of gasoline (MW = 100), calculate the fraction of VOCs in the ..
A sample of nitrogen has a volume of 630 mL at a temperature of 49 degC. Assuming that the pressure is constant, what will be the volume when the temperature is 348.6 degC.
Use bond enthalpies to estimate the enthalpy change for the following gas-phase reaction.
The rate constant of a reaction is 2.75*10^-5 L/mol*s at 195 c and 3.75*10^-3 L/mol*s at 258 c. What is the activation energy of the reaction
Starting with 1.20 mL of an alcohol (MW 88, d = 0.8114 g/mL) and 3 mL of glacial acetic acid (MW 60, d=1.06 g/mL), calculate the theoretical yield in moles.
Imagine gaseous Ar at 298 K confined to move in a two-dimensional plane of area 1.00 cm^2. What is the value of the translational partition function
If 230nm wavelength light were used instead still 75µm what changes would be there compared to part (a)? Looking at the number and the energy of the electron
Treatment of A with zinc amalgam and HCl affords an optically active, dextrorotatory hydrocarbon C. Identify compounds A, B, and C, including stereochemical configurations. Be sure to explicitly draw H and both wedge/dash bonds at any configuratio..
calculate the equilibrium pressure of N2O4(g) and NO2(g). (c) What percentage (by moles) of the original N2O4(g) is dissociated at the new equilibrium position (total pressure = 1.00 atm)?
The crucible is not fired, as the procedure suggests, but had retained some impurities from previous use. The mass of the "dirty" crucible is recorded.
What product or products would you expect to obtain by the addition of bromine to cis-cinnamic acid, assuming that it reacts by the same mechanism as the trans acid
