Title: Redox Reaction Introduction: Some of the most important chemical reactions are Redox reactions. They are also known as oxidation-reduction reactions. This reaction passes one or more electrons from one species to another. The species that loses electrons are being oxidized while the species that gains electrons are reduced. The reaction occurs simultaneously. Numbers are given to each element in a chemical reaction to help us find out which element is oxidized and which is

In this lab we tested to see if the amount of sunlight exposed to the basil seed‚ would affect the growth. The null hypothesis for this experiment was that there would be no statistical difference between the green‚ yellow‚ and red basil seeds’ growth. Three alternate hypotheses are: If we expose the green seed to 48 hours of sunlight and the yellow seed to 24 hours of sunlight‚ then the green seed with grow more than the yellow. The opposite of this hypothesis would alternate 2. Another alternate

ABSTRACT The objective of this project is to optimize the preparation of modified Calcium Oxide (CaO) to capture CO2 by carbonation through hydration of ethanol/water. The carbonation reaction is the basis for CO2 capture systems. However CaO as regenerable CO2 sorbents in industrial processes is limited by the rapid decay of the carbonation conversion with the number of cycle carbonation/ calcination. Therefore Calcium based sorbents have attracted renewed attention as possible sorbents for cyclic

The Enthalpy Change of the Decomposition of Calcium Carbonate _INTRODUCTION_ RESEARCH QUESTION: What is the enthalpy change of the decomposition of calcium carbonate? BACKGROUND: Enthalpy in chemistry can be thought of as the energy contained within the bonds‚ or the internal energy‚ but it is not heat and you can only measure changes in it. When bond bonds break in the reactants energy is given off‚ when bonds form‚ energy is absorbed. If the energy absorbed is less than the energy released

Why Conclusion is Important in Term Papers Writing Conclusion is the last part of any type of paper‚ usually a college term paper comprised of three main parts introduction‚ body and finally conclusion. The conclusion of a term paper should be well written because as it is the last part of a paper so it should have a lasting impression on readers and audience. It is an integral part of any study as it sums up important arguments and its evidence to support and proves the thesis statement. Importance

Look again at Act V Scene 4. To what extent do you find it a satisfactory conclusion to the play? Act V Scene 4 is a satisfactory conclusion to the play Much Ado About Nothing because it includes certain conventions of comedy; an example being the happy ending when Hero and Claudio are reunited and Benedick and Beatrice’s love is made public. There is dramatic irony within this scene as deception is used as Hero pretends to be her ‘cousin’‚ which creates tension as the audience wonder whether

Marcel Pagnol- Le Chateaux de ma mere Discuss the reasons for the sudden change in the conclusion of the book “ Le chateaux de ma mere” by Marcel Pagnol is a memorable‚ enjoyable text in which the story takes an abrupt turn at the conclusion of the book. Pagnol utilises the majority of the text to develop the story of months and a series of events‚ however he majestically creates a sudden change in the final components of the book which span a period of decades. It is not solely the series

activation energy will be attainable. Hypothesis: In a reaction between calcium carbonate and hydrochloric acid‚ the products calcium chloride‚ carbon dioxide and water are formed. I predict that the higher temperature of HCl acid‚ the higher the reaction rate will be‚ this is because at a higher temperature there will more fast-moving hydrochloric acid molecules per set volume. This means that there will be a higher chance of the calcium carbonate molecules colliding with the hydrochloric acid and reacting
