Discussion

Write a minimum one-page (12 font, single spaced) discussion on the experiment conducted this week. Address at least one question in each category as fully as possible integrating the collected data, providing explanations for the observed trends and evaluating whether your original assumptions about the experiment were validated by the results. The assignment will be graded on completeness, clarity of the explanations and the meaningful integration of the collected and calculated data. Correct grammar and appropriate format for the chemical formulae and chemical reactions is expected. You may use the outline included at the end of this document on how to build your essay to address each category.
<ol>
 	<li>(Existing knowledge, research, and views) Explain equilibrium and Le Chatelier’s Principle.</li>
 	<li>(Existing knowledge, research, and views) Describe how the addition of an acid or a base impact the solubility of carbon dioxide in water.</li>
 	<li>(Analysis) Describe what happens to an equilibrium constant as a result of a change in temperature. You may also refer to at least one example from the experiment for your argument.</li>
 	<li>(Analysis) Describe what happens when extra reactants are added to a reaction. Identify at least one relevant example from your experiment.</li>
 	<li>(Assumptions) Predict what would happen when products build up in a reaction and provide at least one supported argument for your choice.</li>
 	<li>(Assumptions) Predict what would happen in the experiment if the carbon dioxide pressure was increased and provide at least one supported argument for your prediction.</li>
 	<li>(Existing knowledge, research, and views) Identify the units for an equilibrium constant and provide a reasonable justification for your answer.</li>
 	<li>(Analysis) Experiments are typically carried out with a control. Identify the control sample in your experiment and provide at least one supported argument for the necessity of using a control.</li>
 	<li>(Experiment design) Propose another experiment that illustrates a chemical equilibrium using a liquid and a gas. Identify the variables that your proposed experiment studies and describe the expected outcome.</li>
 	<li>(Experiment design) Propose another experiment that illustrates a chemical equilibrium using something other than a gas. Identify the variables that your proposed experiment studies and describe the expected outcome.</li>
 	<li>(Analysis) Global warming leads to an increase in the average temperature of the planet and it is caused by greenhouse gas emissions (including carbon dioxide). Predict how the combination of higher temperature and higher carbon dioxide influences the oceans.</li>
 	<li>(Analysis) Coral reefs, like eggshells are composed mainly of calcium carbonate. Their destruction is often linked to the carbon dioxide emissions. Provide a reasonable and supported argument for how that is possible using the solubilities of calcium carbonate and carbon dioxide in water.</li>
