Practical Biodiesel Abstract During the biodiesel practical in the labaratorium we used the following materials: an erlenmeyer, a spatula, a funnel, a heater, a graduated cylinder, a reflux condenser, a beaker, a lab lift, a round bottem flask and a stirring bullet. All these materials were placed in a fume hood. The most appropiate testresult that we could get from this experiment, is a biodiesel with a flashpoint above 130 °C and

within the shale by drilling horizontally, forcing water, sand and chemicals into the rock. In each 10,000 ft well over a million gallons of water is pumped, along with sand in chemicals agents in order to cause fissures. By flowing sand through the well, this acts to keep these fissures open, to allow the natural gas to escape. Between 2005-2009, the House Energy and Commerce committee released a report addressing the chemicals used in the hydro-fracking process. The report stated, “The 14 leading

Chemical Peels Chemical peels are one of the least invasive ways to improve one’s appearance. Peels are a form of exfoliation that assists in cell turn over. Before the age of 30 cells turn over every 28 days. After the age of 30 it’s about 10 days every 10 years. Due to slow cell turn over after the age of 30 chemical peels could improve acne, acne scars, age and liver spots, fine lines and wrinkles, pigmentation, and sun damaged skin. There are three different types of peels: superficial

surroundings, generally using energy from light (photosynthesis) or inorganic chemical reactions (chemosynthesis). They are the producers in a food chain, such asplants on land or algae in water, in contrast to heterotrophs as consumers of autotrophs. They do not need a living source of energy or organic carbon. Autotrophs can reduce carbon dioxide to make organic compounds for biosynthesis and also create a store of chemical energy. Most autotrophs use water as the reducing agent, but some can use other
