EXPERIMENT 7: PERCENTAGE OF OXYGEN IN KClO3 Introduction: In this experiment you will determine the percentage of oxygen in potassium chlorate. You will calculate the theoretical value from the chemical formula and compare your experimental value to the theoretical value. Background: When potassium chlorate (KClO3) is heated‚ it undergoes chemical decomposition. Oxygen gas (O2) is given off and potassium chloride (KCl) remains as the residue. The equation for the decomposition of potassium

Biotechnology‚ Mapua Institute of Technology ABSTRACT In this experiment‚ solubility class of various organic compounds are to be determined. The main objective of the experiment is to identify an unknown compound through the use of preliminary tests such as examination of physical state‚ color‚ odor‚ and ignition properties. Also‚ solubility tests were used to further examine an unknown compound’s solubility class. In this experiment‚ the apparatus used are micro test tubes and droppers for mixing

Salt from green beans Name: Ashni Couprie and Dennise Susanto Class: 5c Introduction From previous experiments we ’ve learned that salt is extracted from green beans. To be more specific: salt is extracted from when the beans are cooked in water in which salt has been dissolved. This experiment is based upon the osmoses theory. According to this theory the cell walls of the green beans are what we call a semi permeable membrane. This membrane only lets water through and not the substance

Seeking For Help Will Rogers once said‚ “A man only learns in two ways‚ one by reading‚ and the other by association with smarter people”. Learning from more experienced and wiser people is much more effective than trying to solve everything yourself. In Langston Hughes’s short story‚ “Thank You‚ M’am”‚ a boy‚ Roger‚ is caught stealing Mrs. Jones’s purse; however‚ instead of reporting it‚ she brings the poor orphan boy to her house to wash his face and to feed him. This story demonstrates the

The effect of varying temperature on thee Rennin enzyme Abstract The purpose of this experiment was to see what affect different temperate had on the reaction rate of the enzyme rennin. The experiment was performed by placing test tubes filled with renin and milk into water bath which was heated or cooled to one of the temperatures trialed. The hypothesis justified because it found because it though data that the enzyme reacted faster with the 45° temperate because it was

Stanley Milgram: ’electric shock’ experiments (1963) - also showed the power of the situation in influencing behaviour. 65% of people could be easily induced into giving a stranger an electric shock of 450V (enough to kill someone). 100% of people could be influenced into giving a 275V shock. The Milgram Experiment Stanley Milgram (1963) Experiment: Focusing on the conflict between obedience to authority and personal conscience. Investigate: Whether Germans were particularly obedient to authority

Abstract Over a two week period of time in the laboratory‚ we experimented and tested the reaction rate of a peroxidase enzyme and the factors that affected it‚ both positively and negatively. The purpose of these experiments was to probe and manipulate the activity of the enzyme peroxidase by varying temperature‚ pH‚ the amount of enzyme compared to the substrate and the effect of hydroxylamine. Peroxidase activity is expressed when the potato extract is subjected to stresses such as low temperature

UV4297 March 24‚ 2010 THE ABERDEEN EXPERIMENT The phone rang yet again‚ but Sarah Mann‚ general manager of the BAE Systems plant in Aberdeen‚ South Dakota‚ was ready. Experience told her what the question would be: Had the “Aberdeen experiment‚” begun by Bob Lancaster when the plant was built‚ undergone any changes over the past quarter century? From the beginning‚ Lancaster’s design and management of the plant‚ which produced missile launch canisters for the U.S. Navy‚ were unusual—and successful
