investigating how the rate of reaction differs when we change the concentration of Hydrochloric Acid whilst reacting with Magnesium. The rate of reaction is explained by the Collision Theory. This theory explains how various factors affect the reaction rates and how chemical reactions occur. The 4 factors of the Collision Theory are: • Temperature • Concentration • Surface area • Catalyst I am investigating how different concentrations of acids affect the rate of reaction. However I must control

LAB 10: NAME: DaeNia La Rodé DATE: 25TH January‚ 2011. FORM CLASS: L6 3 SUBJECT: Biology TITLE: Enzymes AIM: To investigate the effect of substrate concentration on the enzyme amylase INTRODUCTION: Enzymes are perhaps one of the most important proteins of the human body. Enzymes such as amylase‚ an enzyme that breaks down carbohydrates‚ work by means of surface catalysis. In other words‚ the surface of the enzyme enables other molecules to react in a manner they would not be able to without

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

Concentration Camps The Holocaust was traumatizing event in the 1900s. It was a life changing event for the Jews. This time period went down in history. Rudolf Hoss‚ estimated during Nuremberg Trial that nearly three million people died while being held hostage in death camps. Also‚ ninety percent of the ones killed were known as Jews. In death camps the people who were known as “different” suffered from cruel treatment‚ harsh environment and immoral medical experiments. Well‚ we all know HItler

Arnold’s contribution to literary theory is his theories on epochs of expansion and epochs of concentration‚ which throughout the course of this essay will be thoroughly explained. Matthew Arnold‚ a Romantic poet transformed into a critic of the Romantic Age‚ contributes to the English critical theories‚ the concept of epochs of expansion and epochs of concentration. Matthew Arnold‚ poet and critic was born on December 24 1822 in Laleham‚ Middlesex England and passed away April

Based on calculations #7 made above for solving the molecular weight‚ it was identified that the unknown liquid was Butanoic acid: 88.1g/mol. Since the calculated value was 83.5 g/mol‚ it was assumed that Butanoic acid was the only solute out of all that were listed that shared a similar value. In reference to the results and data used for calculation the molecular weight (MW) for the unknown was successfully proven to match the accepted value of 88.1 g/mol. More specifically‚ this was evident due

Abstract The following experiment details the effect of different concentrations of catalase on the production of oxygen and water through the breakdown of Hydrogen Peroxide. In this experiment paper disc where coated in varying concentrations of catalase‚ 0‚ 25‚ 50 75 and 100%. The time taken for the disc to float between two markers on the side of a glass was then recorded. This experiment demonstrates that the higher the concentration of enzyme used the greater the production of oxygen on the paper

plasticity (7). This would suggest that low PIP2 levels in the hippocampus would result in synaptic plasticity deficits as a result. Research has been conducted into PIP2’s involvement in reduced cognition in older brains using the synaptosomes isolated from mice at 4 months‚ 10 months and 20 months old. The results obtained showed that older mice had low levels of PIP2 in the hippocampus as well as high levels of the phosphorylation product of PIP2 called PIP3 and low levels of PLC. The authors suggest
