This experiment was performed to demonstrate a cycle of chemical reactions involving copper. This lab will start with copper as a reactant in the first reaction through a series of five chemical forms of aqueous phase reactions and ending to calculate the percentage of recovered solid copper as a product in the last reaction of the experiment. The experiment resulted in a percent recovery from the cycle of copper reactions of an increase to 139%. . Introduction: The purpose of this experiment is

Work very hard in doing work is really important‚ but we can’t only rely on this to determine the grade of student earns as this can’t show the ability of that student. The more important is that student can get the main idea of the books and express it out and give an excellent work. So achievement should be use to determine students’

The Effect of pH on Enzymatic Reaction Rate Abstract Enzymes are affected by changes in pH. The most favorable pH value— the point where the enzyme is most active—is known as the optimum pH. This experiment was conducted to determine the effect of pH reaction rate on an enzyme‚ catalase‚ from yeast. The experimental results indicate that the catalase worked best at a neutral pH level of seven (7). Introduction An enzyme is a protein molecule that serves as a catalyst. “The basic function of

It is inevitable. It is necessary. It can be shocking. It is a risk and can make or break a thing. Life without it is boring. It can be a friend and a great teacher because it teaches a lot of valuable things that are not learned in school. It can be a great strategy‚ an eye opener to reality‚ and can be a great

CHANGES—AN ANALYSIS OF TUPAC Historians and cultural critics trace the post-modernist hip hop movement which pioneered sampling and graffiti art to the 1970′s‚ New York‚ a movement rooted in the black nationalism of the black panthers post civil rights movement (Price‚ 2006). Hip Hop has become a dominant global youth culture with music‚ art‚ fashion‚ films and Tupac an icon within this culture a “Black Elvis”. Hip Hop has many different sub genres such as conscious‚ gangsta‚ party rap and with

the AVR and we watched clips about the universe inside a Space Dome or Mobile Digital Planetarium. Inside the Space Dome we felt like we are really in the outer space because of the way we viewed the clippings. We learned how physical and chemical changes occur in stars as they grow old and soon explode. Newly born stars are blue and are the hottest ones. They are born as soon as a red star which is also an old star explodes. Stars aren’t the only ones visible during the night. Some nearby planets

Introduction: A chemical reaction is formed of reactants and products. Reactants react with each other to give one or more product. Sometimes we can visualize observations that are characteristic of the reaction. Like for example a release of a gas (bubbles are formed) or a change of color or also the formation of a precipitate. Materiel needed: Test tubes Rack of test tubes Plastic droppers Beakers Procedure: We prepare 7 beakers of 7 different solutions (that we mark from 1→ 7)

What factors will determine liability? The factors that will determine if the teachers are liable is if the incident was unforeseen and if the teacher was supervising the students as required during recess. Teachers are required to use a standard of care‚ but if they act improperly or failed
