Concentration vs Rate of reaction Brandon Introduction A reaction rate is the speed at which a chemical reaction will occur. Heat‚ concentration of a chemical‚ Surface area or a catalyst‚ will affect the rate of reaction. The concentration of a chemical will speed up of the reaction because the reactant particles have become more crowded therefore increasing the chance of productive collisions. In this practical the chemicals will be Sodium thiosulphate and Hydrochloric acid which will produce

The effect of salt concentration on grass growth Abstract Our aim was to test the effect of different salinities on the growth of plants which what we did was measured different amounts of salt dissolved into 2 litres of water‚ watered the plant once with the salt water then for 9 days with pure ware. I found with my investigation that the less the salt‚ the more the growth of the plant. My aim was achieved by measuring the 5 fastest geminating (out of 20) and to measure the differences in growth

Politicians declared that we would never let concentration camps like that of Hitler’s in Nazi happen again. However‚ North Korea has concentration camps in the modern era. But North Korean concentration camps have lasted longer than Nazi concentration camps. No country takes action or helps North Korean political prisoners. North Korea commits crimes against humanity. There are 150‚000 to 200‚000 North Koreans in concentration camps. These Koreans are in death camps for minor crimes and most of

Hypothesis: I hypothesis that the enzyme concentration will affect the rate of reaction but only up until a certain point because there is a limited supply of substrate. Enzymes are protein molecule that acts as biological catalyst by increasing the rate of reactions without changing the overall process. They are long chain amino acids bound together by peptide bonds. Enzymes are seen in all living cells and controlling the metabolic processes in which they converted nutrients into energy and new

MICROBIOLOGY COURSEWORK The effect of antibiotic concentration on bacterial growth Introduction Null Hypothesis- Increasing the antibiotic concentration has no effect on bacterial growth. Experimental Hypothesis- Increasing the antibiotic concentration decreases bacterial growth. Scientific Theory Bacteria are prokaryotes and can be identified by their shape. Spherical bacteria are called cocci‚ rod shaped bacteria are called bacilli‚ spiral shaped bacteria are called spirilla and

The Equilibrium of Religion and Science True science discovers God waiting behind every door. ----Pope Pius XII In the common sense‚ science and religion are considered to be two things at odds‚ for they contradict each other. In the aspects of the exterior‚ it is true. Giordano Bruno was burnt alive by the Catholics for revealing scientific truth. Darwin’s theory of evolution is not taken into curriculum in half of the middle school in US because of the oppression from Catholic. However‚ in
