Method 1. Sterilise all of your equipment with ethanol‚ blue flame or disinfectant if you can flame it. 2. Collect all equipment together ensuring you collect your goggles and gloves as you are using a flame and gloves and goggles are part of safety precautions. (don’t wear gloves with messing with Bunsen burner only goggles‚ but use gloves when messing with chemicals ensuring goggles on all the time) 3. Clean your surface with disinfectant to sterilise your lab work surface‚ this will prevent

Replanting Palm Oil – “The Next Decade” For the next ten years this replanting presents a great opportunity to produce sugar‚ ethanol‚ RTP Green Fuel‚ building products‚ stock feed‚ plant derived plastic packaging‚ and paper. At the same time the replants will increase the yield of oil per hectare through use of better Palm Oil seedlings and their growth boosted with irrigation

If the plastic floated‚ you will place it in a mixture of ethanol and water using the following steps(this is creating a mixture with a density between 0.920 g/mL and 0.953 g/mL): a. Place

cost each year. The second benefit is the environment. E85 is made with a gasoline-ethanol blend containing 51% to 83% ethanol depending on geography and season. Using ethanol reduces imported oil and lowers greenhouse gas emission (U.S. Department of Energy‚ n.d. ). The overall benefit is on the environment of reducing some of the effects of using petroleum-based fuels. If the

When you blow out a normal candle‚you see thin smoke rising up. The wick is hot enough to vaporize the wax but not hot enough to re-ignite it. In trick candles however‚ they add an ingredient that ignites at a lower temperature then the paraffin wax. This ingredient is usually a pyrophoric metal(metals which ignite at extremely low temperatures). MAGNESIUM is the most commonly used pyrophoric metal in trick candles‚ with the magnesium flakes embedded in the wicks. When you blow out the candle

The buffer degrades the protein enveloping the DNA found in onion and cheek cells Cheek cells are obtained from gargled gatorade. Extracts are then filtered and subjected to addition of chilled ethanol. DNA is insoluble in alcohol making it to precipitate‚ DNA is then extracted. Keywords: DNA

biodiesel. Unlike ethanol‚ biodiesel can be used as a blend or pure biodiesel in standard diesel engines with little to no adaptations. It also burns a lot cleaner than petro diesel and can extend the life of the engine drastically. Procedure Biodiesel is very versatile and can be produced from many different things. In most cases biodiesel can be produced by transesterification of free fatty acids in which a catalyst sodium hydroxide is mixed with an alcohol such as methanol or ethanol‚ washed‚ and

biofuels such as biodiesel and sugar- or starch-based ethanol‚ evidence suggests that transportation fuels based on lignocellulosic biomass represent the most scalable alternative fuel source1. Lignocellulosic biomass in the form of plant materials (for example‚ grasses‚ wood and crop residues) offers the possibility of a renewable‚ geographically distributed and relatively greenhouse-gas-favourable source of sugars that can be converted to ethanol and other liquid fuels.

CHEM 1211 L Principles of Chemistry Lab 16 February 2004 Lab Report 1 Introduction The purpose of this project is to identify an unknown organic acid (X) by conducting various experiments to determine the acid’s unique properties. By determining selected constant properties of the unknown and then comparing these properties to the constant properties of known substances‚ it is possible to identify an unknown substance. The properties used to identify the unknown must be intensive‚ or independent

In part 2 of the experiment I had to measure out 15cm3 of ethanol‚ which I could have measured out incorrectly could have been one of the possibilities to cause an increased a experimental error‚ when I added the crude aspirin to the ethanol if I didn’t boil them at a constant temperature of 75oc‚ if I let them temperature rise or fall out of limits it could lead to a higher percentage of experimental
