A fictional company has been producing propene oxide, C3H6O, from propene, C3H6, with a 96.0%yield. The process requires the use of a compound called m-chloroperoxybenzoic acid, C7H5O3Cl, which can be abbreviated as mCPBA. The entire reaction takes place in the solvent dichloromethane, CH2Cl2:

C3H6+C7H5O3ClCH2Cl2????96.0% yieldC3H6O+C7H5O2Cl

The initial propene concentration in the solvent is 21.0 g/L.

Consider the prices of the following substances.

Also consider that the cost of waste disposal is $5.00 per kilogram of propene oxide produced.

Part A

A relatively simple way of estimating profit is to consider the the difference between the cost (the total spent on materials and waste disposal) and the earnings (the price at which the product can be sold).

Calculate the profit from producing 32.00kg of propene oxide.

Express your answer numerically in dollars using three significant figures

The company is developing a "greener" method of making propene oxide from propene using hydrogen peroxide, H2O2, in supercritical water with a vanadium catalyst. In the reaction 1.00 kg of vanadium catalyst and 32.0 kg of water are used for each kilogram of propene. 75 % of the vanadium catalyst can be collected and reused in a subsequent batch:

C3H6+H2O2V, H2O????89.0% yieldC3H6O+H2O

Consider the prices of the following substances.

There is virtually no waste produced with this green process and there is no waste disposal fee, but the yield is only 89.0%.

Part B

Calculate the profit from producing 32.00kg of propene oxide by this alternative green process.

What are referred to as ‘particles’ in cryo-EM of proteins?

if an ATP molecule is hydrolyzed (by two water molecules) all the way to AMP (and two Pi) in two steps, how many total kcal/mol of energy could be released? Explain.

Using this equation.

ADP + H2O -> AMP + Pi + 7.3 kcal/mo

A mixture initially contains A, B, and C in the following concentrations: [A] = 0.400M , [B] = 0.700M , and [C] = 0.700M . The following reaction occurs and equilibrium is established:

a) Account for the fact that there are four different types of H atoms (four non-equivalent H types) in propene.

b) Explain why the NMR spectrum of cyclohexane,below, at room temperature gives one broad peak for all 12 protons instead of two seperate peaks for the axial and equatorial hydrogens

Can someone explain to me why does increasing the electrolyte concentration can increase the electroplating rate/or metal deposit...? Take copper sulphate as an example. Better explanation with pics...And just don't go too far beyond the Faraday's law and please try to explain it in a more 'Chemistry' way. Thanks!

3. ADP-Glc pyrophosphorylase (AGPase) is a key enzyme in the biosynthesis of starch. Using AGPase as an example, describe how the regulation of this one enzyme can control the overall flux of carbon through starch biosynthesis in photosynthetic tissue.

Determine the equation for the best straight line for the calibration curve from the following set of absorbance/concentration (mg/100 mL) data: 0.96/0.0, 0.83/10, 0.66/20, 0.49/30, 0.36/40, 0, 19/50, 0.08/60.

What method did you use to obtain the equation for the best straight line, what is the value of Ao, and what are the numerical value and units of k?

What is the [OH-] of a 1x10-3 M solution of NH4Cl?

A chemistry student needs to standardize a fresh solution of sodium hydroxide. She carefully weights out 305.mg of oxalic acid(H2C2O4), a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in 250.mL of distilled water. The student then titrates the oxalic acid solution with her sodium hydroxide solution. When the titration reaches the equivalence point, the student finds she has used 69.4mL of sodium hydroxide solution. Calculate the molarity of the student's sodium hydroxide solution. Be sure your answer has the correct number of significant digits.
