Introduction As stated in the Bio 107 Laboratory Manual‚ alcohol fermentation in yeast breaks down sugars into carbon dioxide and ethanol which is very important in many fields such as biofuel‚ industrial‚pharmaceutical and others. Amylase is an enzyme that break down starch/amylose in plants. Corn kernel contains starch‚ sugars and cellulose. This experiment focused on the effect of amylase on corn extract in respect to the rate of fermentation. Since amylase breaks down starch‚ the part of corn

city implements the biofuel as one of the energy sources. Firstly‚ the implementation of biofuels can help the public to fight against the ever rising oil prices and reduce the dependency on petrol. As the conventional energy sources such as fossil fuels‚ coal and natural gas will be used up in the near future‚ the prices of gasoline keep rising for the recent years such that it has become an extra burden for the public to stand for such high oil prices. With the introduction of biofuel in Hong Kong

COLLIGATIVE PROPERTIES 1. Calculate the vapor pressure when 10.o mL glycerol (C3H8O3) is added to 500.0 mL water at 500C. At this temperature the vapor pressure of pure water is 92.5 torr and its density is 0.988 g/mL. Density of glycerol is 1.26 g/mL. 2. Calculate the boiling point and freezing point of the solution if 1.00 kg of ethylene glycol (C2H6O2) is added to a car radiator which contains 4450 g water. a. Kb of water = 0.512 oC/m at normal boiling point of 100oC b. Kf of water

Fuels Research Question How does the chain length of an alcohol (1‚ 2‚ 3‚ 4 or 5 carbon atoms) affect its boiling point (°C)‚ determined using micro boiling point apparatus (heating the liquid in a capillary tube placed in paraffin oil)? The alcohols tested will be methanol (1 carbon atom)‚ ethanol (2 carbon atoms)‚ propan-1-ol (3 carbon atoms)‚ butan-1-ol (4 carbon atoms) and pentan-1-ol (5 carbon atoms). Variables Variable Description Independent This is the variable that will change; the chain

Heat of Mixing: Ethanol and Water Abstract The temperature change when known amounts of water and ethanol were mixed was determined to see the enthalpy change in an isothermal and isobaric environment. Agreeable data was found compared to similar experiments. As the mole fraction increased of the solution so did the enthalpy until a certain limit of about 0.32. Since water’s structure and unique properties affect many aspects of a solution‚ the solutions enthalpy’s decreased at a certain time

Alternative Fuels People in America do not realize the fact that driving their vehicle is one of the regular activities that they do that has one of the largest impacts on the earth. With more and more cars in use each day‚ the more fossil fuels are called for. Fossil fuels are natural fuels that were formed from the remains of living organisms. These fossil fuels typically take millions of years to be formed. Since most fossil fuels are being imported due to it taking a huge amount of time

driving drunk is that the police are not able to check each and every car and even if they catch any one the police can be easily bribed. So there is a need for an effective system to check drunken drivers. In alcohol detection system the ignition of the fuel is regulated by a sensor circuit. The sensor circuit is used to detect whether alcohol was consumed by the driver recently. The design also consists of a blood pulse rate sensor which is used to check whether alcohol is consumed while driving.
