Chemical Reactions I. Purpose – The purpose of this lab was to observe different type of chemical reactions to write and balance chemical equations. II. Hypothesis: If you mix two chemicals together‚ then they will change color and/or bubble/fix. III. Procedure - Workstation 1: 1. Light the Bunsen Burner 2. Add 5 – 8 mL of HCL to a test tube that’s in the test tube rack 3. Drop a 2 – cm piece of Mg ribbon into the test tube 4. Record Observations 5. Clean Workstation

HOW FAST ARE CHEMICAL REACTIONS? THEORY The study of reaction rates‚ how fast or how slow a reaction takes place‚ is known as chemical kinetics. The rate of chemical reactions varies greatly. Some reactions‚ such as the explosion of an atom bomb are uncontrollable. Reactions like the decay of radioactive carbon (14C) are so slow that it takes centuries to see any noticeable change. Between the two extremes are reactions that can be measured in the laboratory. There are several factors that

Friction- what stops your car; When you hit your brakes‚ it stops the tires‚ and that dragging is created by friction. 6. Traction- a force that makes heart and helps keep the tires on the road 7. Centrifugal Force- the apparent force that draws a rotating body away from the center of rotation; caused by the inertia of the body as the body’s

Investigating Chemical Equilibrium Date: 30th April 2013 Due Date: 15th May 2013 Prepared For: M. Seraji Prepared by: Andrea Odunze Abstract Many reactions proceed to a state of equilibrium. A chemical reaction at equilibrium‚ where the rates of the forward reaction and reverse reaction are equal‚ looks like this: A + B AB There are three factors‚ according to Le Chatelier’s principle‚ that affect the equilibrium position and equilibrium constant. These are the concentrations of products

No human data was found on teratogenicity or reproductive effects of Dicamba (NPIC‚ 2012). The chart (NPIC‚ 2012) below contains the toxicity classification for Dicamba regarding the acute oral‚ inhalation‚ dermal‚ primary eye irritation‚ and primary skin irritation effects. It is important to note that not a lot of information is available regarding the chronic toxicity of Dicamba in humans‚ the U.S. EPA has not found any evidence regarding Dicamba disrupting the Endocrine system‚ and Dicamba is

On the other hand‚ imagine how taken aback people are to find themselves dependent on chemical substances when there were no apparent clues suggesting they might be susceptible to active addiction. This sometimes happens when a person is prescribed pain pills after surgery or for pain management or a person decides to experiment with heroin‚ and the obsessions/compulsions of addiction raise their monstrous heads without warning. There is no pre-emptive strategy for this. So‚ sometimes people

Americans consume food at an alarming rate without even stopping to think of what they really might be eating or how it ended up on their plate. If we just took the time to see how our food systems worked‚ we would notice the domino affect trickling down from government to average day Americans. In order for us to be able to grow and produce food‚ farmers are paid by our government in the form of subsidies. These crops often times do not grow naturally from the ground. Chemicals are pumped into the
