For this assignment‚ you will be designing a lab to investigate factors that affect the rate of a reaction. You are not required to conduct the experiment‚ but it may be beneficial to do so if you can acquire the materials needed for your design. The reaction that you will be investigating is the reaction that occurs when an Alka-Seltzer tablet is placed into a given amount of water. Alka-Seltzer is an over-the-counter antacid and pain relief medication that is dissolved in water before it is

this experiment I will investigate the relationship between the concentration of the hydrochloric acid and the rate of a reaction. To find this out I will react different concentration of hydrochloric acid and magnesium‚ from there I will monitor the gas (hydrogen) produced and analyse the results. Prediction: I predict the higher the molarity of the hydrochloric acid the faster the rate of reaction therefore the quicker the gas will be produced in the specific time interval. Overview of the

Are people taking marriage less seriously as divorce rates rise? As divorce rates in the United States rise it seems that two groups of people are formed: one group deciding marriage isn’t for them and the other group being even more determined to make marriage work.

Oil and gasoline prices had been a problem since individual vehicles had actually entered the market. After the Katrina United States current economic growth is not even sustainable under the recent oil price surge. Even though the Department of Energy does not feel that oil prices are high enough to cause a recession‚ the consequence of high energy costs cannot go unaddressed. Government has to start looking and actually spending money on solutions to this consumption problem immediately. This

Erin Bolton Chemistry Lab Report April 29‚ 2015 Lab: Reaction Rates Introduction: In this experiment we studied the reaction of potassium persulfate‚ K2S2O8‚ with potassium iodide‚ KI. All chemical reactions have an energy barrier to overcome before the reaction will proceed. We will record data based on the concentration‚ temperature and catalyst for each experiment. Once this has been completed it will be graphed. Procedure: Due to the chemicals being used having hazard gloves are used

ensuing Communist takeover and the events in George Orwell’s novel Animal Farm. It was a time when a totalitarian government came to power and thus a climate of fear existed. Even when the more discerning animals questioned the pigs’ actions‚ they were trapped into a submission of power due to the manipulation of language and propaganda tactics employed by the pigs. Animal Farm in Historical and Social Context In many ways‚ Animal Farm is a complete allegorical / fable –like retelling of the founding
