Synthesis of Banana Oil: What are the gram components of each distillate? What is the percent yield from the peak area?

2.16 mL Isopentyl alcohol, 2.3 mL glacial acetic acid, and 0.15mL of sulfuric acid was used to form 1.3407 g of "banana oil"

A gas chromatogram revealed that our final product contained 4 peaks. 1. 0.412 @ 9.90458 % area, 2. 1.481 @ 1.30885% area, 3. 1.722 @ 3.14633% area, and 4. 2.040 @ 85.64024% area. How can I calculate the percent yield from each peak area?

3. Summarize the benefits and drawbacks of OLEDS over inorganic semiconductors.

Titration of acid with base is an exothermic reaction. Neutralization of 15 mL of H3PO4 acid with 8 mL potassium hydroxide released 780 J heat. Find molarity of the acid and the base?

H3PO4 (aq) + 3 KOH (aq) = K3PO4 (aq) + 3 H2O (l)    

Delta H X rxn = -124.8 kJ

Why is UV-light used for the “reading” of the TLC-plate?

Why is substitution of a Pro amino acid in the middle of an alpha-helix always disruptive?

Consider the titration of 50.0 mL of 0.20 M  NH3 (Kb=1.8×10−5) with 0.20 M  HNO3. Calculate the pH after addition of 50.0 mL of the titrant.

Use tabulated half-cell potentials to calculate ?G?rxn for each of the following reactions at 25 ?C

Pb2+(aq)+Mg(s)?Pb(s)+Mg2+(aq) answer in kJ

Br2(l)+2Cl?(aq)?2Br?(aq)+Cl2(g)

Ethanol is produced commercially by the hydration of ethylene:

C2H4+H2O-->C2H5OH

Some of the product is converted to diethyl ether in side reaction

2C2H5OH-->(C2H5)2O+H2O

The feed to the reactor contains ethylene,steam,and an inert gas. A sample of the reactor effluent gas is analyzed and found to contain 43.3 mole% ethylene, 2.5% ethanol, 0.14% ether, 9.3% inerts, and the balance water.

a. Take as a basis 100 mol of effluent gas, draw and label a flowchart, and do a degree-of-freedom analysis based on atomic species to prove that the system has zero degrees of freedom?

b. Calculate the molar composition of the reactor feed, the percentage conversion of ethylene, the fractional yield of ethanol, and the selectivity of ethnaol production relative to ether production?

Describe Le Chatelier's principle and discuss how it can be used to understand the problem created when Flint changed their treated water source from Lake Huron to the Flint River.

In an experiment, 11.5 grams of NO₂ gas are placed in a container at 30.00°C and 1.26 atm. What is the density of the gas?

A monoprotic acid with a Ka of 7.79E10-5 has a partition coefficient of 3.4 (favoring octanol) when distributed between water and octanol. Find the formal concentration of the acid in each phase when 100 mL of 0.10 M aqueous acid is extracted with 31 mL of octanol at (a) pH 4.00 and (b) pH 9.00.

an explanation of why oxygen binding proteins like myoglobin and hemoglobin contain heme prosthetic groups, and how the protein structure surrounding the heme affects the relative affinity for oxygen vs. carbon monoxide.

A swimming pool in the neighborhood of a smelter receives atmospheric SO2 deposition. The average concentration over the pool is 300 micrograms SO2/m3. If SO2 deposition velocity is 1.2 cm/sec and all SO2 deposited on the pool is transformed to H2SO4,how much NaOH must be added to the pool (moles per square meter of surface area) weekly to neutralize the H2SO4 and prevent the pool from becoming acidified?
