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

DESIGN AN EXPERIMENT: THE BIGGEST BLOWER EXPERIMENT Design an Experiment: The Biggest Blower Experiment Problem Statement: You have a pack of Hubba Bubba Bubble Gum. Does the amount of sugar in this gum affect the size of the bubble you blow?? Hypothesis: I think that sugar in any gum affects the size of the bubble you blow. I think this because I was watching “The Next Great Baker” and someone was melting sugar and when it cooled off a little he used a balloon blower to make bubbles out of

Sexual orientation in the House of Religion In the world of religion there can be a number of do’s and do not’s‚ which in a better lack of terms the do not’s are described as sinful. Being gay or lesbian in the Christian community is acknowledged as a sin; God speaks about man and woman‚ not woman and woman or man and man joining as one. There are so many excerpts stating” thou shall not” –exodus 20:13 The Bible ….well I think you are familiar with that scripture! I took the opportunity

Critical Thinking Stanley Milgram Experiment I feel the reason the Milgram Experiment subjects were lacking the moral and critical thinking of how they reacted to the experiment was a multitude of things such as. The subjects felt they had to because they were being told to by “people of authority” They also felt that since they were participating in the experiment and they were only doing “as told” then they were okay to proceed. Some also stated that do to the trust they had for the school and

chemical reactions while using less energy. They also remain unchanged after use‚ which enables it to be used repeatedly. Cells have special catalysts called enzymes‚ which are specialized proteins that help accelerate chemical cell reactions. (Evert‚ RF & Eichhorn‚ SE 2013). Enzymes also control plant metabolic processes such as respiration (Evert RF‚ Eichhorn SE & Perry JB 2013). This experiment focuses on the enzyme catalase. Catalase breaks down hydrogen peroxide into water and oxygen. Hydrogen

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.

Investigate: Whether Germans were particularly obedient to authority

Many people believe human beings should not be used as test subjects in experiments. The use of human beings for experiments or research can have lasting negative effects on that individual such as emotional and psychological damage. The Milgram experiment even though it was a hoax had a lasting effects on many of it’s participants in both positive and negative ways and is a example of why humans should not be used as test subjects. The Milgram experiment was conducted by Stanley Milgram a assistant

Introduction In my report I will discuss what I did as an experiment and what I hope for it to achieve. Firstly I carried out an experiment to assay the effectiveness that a range of disinfectants have on the growth of ecoli and whether or not it can prevent it from growing. From the experiment i should be able to see that some disinfectants have a greater effect than others do. From this I shall then draw a conclusion and evaluation on what was the most effective‚ and could there have been any
