ETHANOL (E85): Types of fuels are ethanol‚ natural gas‚ diesel and hydrogen. Ethanol is simply grain alcohol obtained from corn. The corn is ground to powder form and mixed into a mash that is distilled to obtain ethanol which is a flammable liquid and then used as fuel. The ethanol could be mixed with gasoline blend in order to obtain reduced cost. In addition‚ the emission of Co2 would be reduced‚ but not completely eradicated because of its content of 90 percent gasoline and 10 percent ethanol

Popper was a famous philosopher who wrote‚ that any theory that could not be falsified and tested to be `wrong`‚ could not possibly be a “scientific” experiment. The fact that Locard’s Principle explains that `every contact leaves a trace`‚ would surely mean that the exchange takes place between all the objects in contact. If a glass cup was placed on a wooden table‚ according to Locard’s principle there should be small particles of wood on the glass and glass on the wood! This exchange though is just

these results as I believe the more Magnesium there is the more Oxygen it will take on to form the Magnesium Oxide and so believe the results should gradually get heavier and heavier as the Magnesium gets heavier and heavier. The equation for this investigation would be Mg + O2 MgO which would balance as 2Mg + O2 2MgO. This is done as the Oxygen has two molecules which would need two Magnesium molecules to balance it out.

* Biology Investigation 3.1 Porcellio Scaber (Slater‚ Woodlouse) Task 1 The crustacean Porcellio Scaber‚ or more commonly known as the woodlouse‚ is a species usually found in leaf litter or in fallen trees and bark. It feeds on detritus like many other isopods of its type‚ and is generally predated on by small mammals‚ lizards and some insects. The woodlouse habitat reflects its need to avoid warm and dry areas. The woodlouse is prone to desiccation (drying out) due to its body’s large surface
