    In the lab testing the heat of a reaction to understand changes in enthalpy in an exothermic reaction‚ the group hypothesized that if the amount of reactant is changed then the amount of heat produced (exothermic) will increase. This hypothesis was supported through the data as each of the six trials produced heat and the larger the piece of magnesium the larger the change in heat was. In the first trial the group had .085 grams of Mg and after being placed in 3 ml of 21.8℃ HCl the temperature of

    and a hole was drilled with a stir stick on the top of the taller cup to allow the stir stick and a thermometer reach the chemical reaction. With the calorimeter set up and ready‚ the experiment was ready to be conducted. The calorimeter was placed on a metric scale and tared. Then 2.5g of a substrate was measured out using a small scoop and placed in the calorimeter. A scale was used to control the amount of substrate to 2.5g in each trial. Then 20 ml of distilled water was measured using a 50

    complex reactions and reaction sequences‚ where raw materials react together to give the product. Such chemical process often releases energy‚ in the form of heat‚ and the reaction is described as exothermic. Many of these reactions may also evolve gases at high rates‚ and could cause reactor over-pressure. Thermal runaway reaction Runaway reactions are thermally unstable reactions where the heat of reaction can raise the temperature of the reactants sufficiently to accelerate the reaction rate out

    Suggested Ice Breaker/Energiser Activities 1. Fear in a Hat Fear in a Hat (Also known as Worries in a Hat) is a teambuilding exercise that promotes unity and group cohesion. Individuals write their personal fears (anonymously) on sheets of paper which is then collected in a hat and read aloud. Each person tries to describe his or her understanding of the person’s fear. This leads to good discussion centred around the fears. This teambuilding exercise requires writing utensils‚ sheets of paper

    Reaction on Reaction Paper The first thing that came to my mind when I have heard about Reaction paper is “What exactly is it?” and before I get an understanding of that‚ I resisted that change. But later‚ when I have studied about it and understood its purpose‚ I have started thinking “Why people avoid change at the first look without an analysis?” The general human tendency is to live in a comfortable zone in which he has lived for quite some time. He draws a circle‚ thinks that circle is his

    Abstract Christy Light Period 2 “Comparing the Coolant Effects of Dry Ice and Ice” What we learned in this lab is how to compare the abilities of dry ice and solid water to act as heat absorbers. This mean that we had to compare which substance had the better result of absorbing more heat. We also learned to determine which substance was the most cost effective. We also learned how to determine the amount of heat each substance absorbed and compare which one absorbed the most heat. The first
