CHML 1046 General Chemistry 2 Laboratory Experiment “The Rate Law of an Iodine Clock Reaction” Objectives: To apply method of initial rates for investigation of influence of concentrations of reactants on the rate of the reaction. Determine the rate law of a particular reaction experimentally. Observe the effect of catalyst on the reaction rate. Examine the influence of temperature on the rate of this reaction. Calculate activation energy for the reaction from rate constants at two…

Bullets that were lodged in the victim skull were sent to ballistics to determine what type of gun was used to commit the murder, the make and model, toolmarks on the bullet casing also determine the make and model of the gun, before all this is determine the bullets must be placed in an evidence bag and then placed in an evidence locker until it is sent over to ballistics for testing. “With the exception of a shotgun, whenever a gun is fired, microscopic characteristics or imperfections are…

Medical devices are the crucial components of health care system, especially the patient care which may include uncomplicated, devices employed during medical examinations, such as tongue depressors and thermometers, or sophisticated life-saving implants like heart valves and coronary stents. They play an increasingly vital role in health care delivery globally.103 Typically, the purpose of a medical device is not attained through any pharmacological, immunological or metabolic means. Medical…

less and less in each town. Finn knew if he didn’t find something to ease the grumbling of his stomach, he was going to die. Finn and the hound had traveled at least two miles when the sun started to sink below the trees. Finn pulled out his thermometer to see if the temperature had changed. His eyes had to focus on the tiny numbers for a minute before he read “negative seventeen” out loud. Finn knew he why he couldn’t feel his toes anymore. They were frostbitten and turning blue. He decided…

from the emissions of an industrial society.”(Wired). This process will diminish the Carbon Dioxide contaminate. However it will not move the more stubborn contaminate of Mercury. Some of the kilograms were held in labs that contain mercury based thermometers and therefore were exposed to Mercury. The reason why it is very difficult to remove is because mercury forms a strong metallic bond with platinum. So this method of cleaning would help make the kilogram more accurate but it wouldn’t make…

Introduction: Solubility is the “ability for a given substance, the solute, to dissolve in a solvent” . The effect of temperature on solubility is that when heat (energy) is added, it increases the speed on which molecules and particles move, therefore making it a quicker process. Where as with cooler temperatures there aren’t as many particles because the solvent doesn’t contain as much energy as warmer temperatures, therefore not dissolving as well as it could if it was warmer. To make jelly…

Ask a question, form a hypothesis, perform an experiment, collect data, and draw a conclusion, these are steps that are drilled into us from elementary school on how the scientific method works. This is an extremely linear and conclusive approach, which does not do justice to just how complex and iterative the scientific process truly is. Science is never concludes and certainly does not follow a predetermined list of steps. However there are certain things that go into every scientific…

through many ice ages and have always reversed them. The climate has been on a record for high temperatures and has returned to normal temperatures. Nature will adjust accordingly. The easiest way to see increasing temperatures is through the thermometer records kept over centuries. There is not enough historical data available to validate that global warming is real. Since scientists do not have data gathered from the first human who…

Thermodynamics deals with the relationship between heat and mechanical energy. There are four laws of thermodynamics. Zeroth law of thermodynamics – If two thermodynamic systems are each in thermal equilibrium with a third, then they are in thermal equilibrium with each other.First law of thermodynamics – Energy can neither be created nor destroyed. It can only change forms. In any process, the total energy of the universe remains the same. For a thermodynamic cycle the net heat supplied to the…

student site sat on the top of my regularly visited webpages. I enjoyed playing the minigames, especially one on spinoff technology. I found it fascinating how engineers used space technology to improve everyday life with inventions such as in-ear thermometers and cordless drills, and decided to write my essay on engineering. Still, I hadn’t done anything to prove myself as a future engineer. Engineers designed solutions, but my parents (lovingly) joked that I practically had a PhD in creating…
