The Fermentation and Distillation of Alcohol By Bhanupriya Chettiar 301 Group Members: Bhanupriya Chettiar‚ Rachel Min‚ Zoe Chandler‚ Bianca Main Aim The aim of the practical is to prepare ethanol by fermentation and to isolate it by fractional distillation. Introduction This practical’s aim is to prepare ethanol using two steps; fermentation and then fractional distillation. Many alcoholic drinks for example‚ brandy and whisky‚ are prepared using this method but to a larger scale. The first

The Rate Of Photosynthesis: Lab report 1) Construct a graph of your data 2) Using the graph‚ estimate the time at which 50 percent of the leaf disks were floating on the surface. The point at which 50 percent of the leaf disks are floating will be you point of reference for future investigations Using the graph the estimated time that roughly 50% of the leaf disks were floating on the surface was around the 10th minute. At the 10th minute our number rose up to

Photosynthesis Experiment Introduction Photosynthesis is a process used by plants‚ making inorganic molecules into organic molecules (food) using sunlight. Carbon dioxide + Water (mainly from rain) Glucose + Oxygen From this process‚ carbon dioxide comes from environment. Glucose‚ as a product is used to make energy for growth. Lastly‚ the oxygen is a waste product in this chemical reaction‚ which become part of the Earth’s atmosphere. At this experiment‚ carbon dioxide and water

Energy Systems Our body needs a supply of energy to complete day to day tasks and to simply be able to move. We have more than one energy system‚ we have 3 in total and these are * ATP (anaerobic) * Lactic acid (anaerobic) * Aerobic (aerobic) All three off these energy systems are fuelled by the same chemical called ADP-PC. These systems produce this chemical at different speeds‚ for example the ATP system produces the chemical very fast as for the aerobic energy system produces it

would anyone use solar energy as an alternative energy to solve the world’s pollution problem? As humans‚ everyday we burn many different types of fossil fuels to produce ourselves electricity and to power up our vehicles‚ and so we create a lot of pollution‚ making this our own fault. With our modern technology and the abundance of the sun’s energy‚ solar energy has the ability to provide the world with electricity and different types of fluid (“Solar Energy”). Solar energy is ?e energy source. It

Absence Management Absence management is the effective monitoring and management of employees who are off work due to sickness related or unauthorised absence from work over both short term and long term periods of time. Sickness absence in the work place usually varies in length but they are most usually commonly grouped as:- • Short-term – absences of less than five days • Medium-term-absences of one to four weeks • Long-term – absences greater than four weeks The most

Davis’ presentation of the social‚ realist‚ drama "No Sugar" can be considered as a forum to highlight the impacts of the European social and political philosophy of the early 20th century on Aboriginal society. It is a political text that exposes social issues. It expresses these issues using the form of drama and the use of staging conventions to challenge the audience into developing an opinion on the topics. The play was staged on a perambulant model‚ meaning that the action of the play shifts

antibiotics. For this reason‚ it is important to test and observe unknown organisms in the lab to continually improve the health and well being of society. The objective of this report was to first isolate a single colony of an unknown culture on a LB agar plate. From here‚ a slant was made and used for multiple types of testing in order to determine the identity of the unknown organism. The tests performed to identify the unknown organism included Gram Staining‚ Fluid thioglycollate/aero-tolerance test
