PRELAB CALCULATIONS: When making biodiesel from virgin vegetable oil, a straight forward recipe is followed. For every 1L of vegetable oil, 0.2 L of methanol is added and 8.0 g of pure KOH. 1. In this lab we will starting with 250 mL of vegetable oil. Calculate the amount of methanol and pure KOH required to convert 250 mL of vegetable oil into biodiesel.

QUESTION 2 To facilitate the transesterification process to form biodiesel, we utilize sodium methoxide. Why don't we just use a solution of sodium hydroxide? O NaOH is too basic, resulting in a series of elimination reactions with alkenes as the products. The methoxide becomes the new ester. The hydroxide with generate a carboxylic acid derivative that would react and form soap. NaOH wil cause the transesterification process to go completely in reverse and thus stop the formation of biodiesel Sodium...

Biodiesel is most frequently produced from vegetable oils however, lignocellulosic feedstocks can be converted to biodiesel using oleaginous yeasts. Lignocellulosic feedstocks are also highly valued for bioethanol production. For both processes wheat straw (LHV 19 MJ/kg) is processed through a steam explosion pre-treatment followed by enzymatic hydrolysis to recover 92% of available hexose and 98% of available pentoses. The organic residue material that remains after sugar extraction has an LHV of 22 MJ/kg-od and can be combusted to generate energy....

Indicate which of the following statements about the electromagnetic spectrum and IR spectroscopy are true and which are false. In any cases where the statement is false, explain how or why the statement is false. Infrared (IR) light is in the gamma ray part of the electromagnetic spectrum. Electromagnetic radiation is characterized by its mass and force. UV-Vis spectra are normally scanned in the 4000-600 cm-1 region. The fingerprint region on an IR spectrum is the easiest to interpret. Stronger...

QUESTION 3 Oily oil company has decided to introduce three oil mixes made from blending two or more 15 Marks] oils. One jar of olive-vegetable oil requires 6 oz each of olive and vegetable oils. One jar of vegetable peanut oil requires 10 oz of vegetable oil and 6 oz of peanut oil. Finally, one jar of olive-vegetable-peanut oil requires 3 oz of olive oil, 7 oz of vegetable oil, and 2 oz of peanut oil. The company...

Question 4 of 4 > Atomic emission spectroscopy and the method of standard addition are used to determine the Nat concentration and its uncertainty in an unknown sample. Increasing amounts of a 1.75 pg/mL standard Na' solution are added to a series of volumetric flasks containing 15.00 mL of the unknown solution. The volumetric flasks are then diluted to a final volume of 200.0 mL. Atomic emission spectroscopy is then used to measure the emission intensity of each solution Final...
