In 1905‚ Frederick Blackman‚ a British physiologist‚ concluded that photosynthesis‚ the capture of light and conversion of it into chemical energy is a two-way process‚ of which only one uses direct light to trap radiant energy. In the Hill Reaction activity‚ our group will be focusing directly on the light dependent reaction. The overall purpose of this experiment is to try to prove the hypothesis that this reaction does produce compounds that have the energy of light. The first of the two major

Chemistry of Bath Bombs Date: 16th May 2014 Introduction – When sodium bicarbonate and citric acid mix in water they dissolve‚ the sodium bicarbonate reacts with the citric acid to form sodium citrate and carbon dioxide. The carbon dioxide then bubbles out as a gas‚ which makes the bath bomb break up‚ in this experiment 3 tests will be conducted in order to find the correct ratio of bicarbonate soda and citric acid to create the

IB1 Chemistry Practical #8 ANALYSIS OF ASPIRIN TABLETS For a long time the bark of the willow tree (salix alba) was used as a traditional medicine to relieve the fever symptoms of malaria. In the 1860’s chemists showed that the active ingredient in willow bark is salicylic acid (2-hydroxybenzoic acid) and by 1870 salicylic acid was in wide use as a pain killer (analgesic) and fever depressant (antipyretic). However‚ because it is a relatively strong acid‚ salicylic acid has the undesirable side effect

Competition in school is harmful to the students. As unglamorous as it sounds‚ the purpose of a public education is to prepare the young person to enter the workplace as a fully functional worker. Competition encourages rugged individualists. The workplace needs team players who will cooperatively work together to meet common goals. The workplace does not need a group of stars who will not share the bonus and who work alone rather than working together. The more successful competitor‚ winner‚
