    Safety Precautions for Synthesis of Acetic Anhydride Acetic Anhydride Acetic anhydride is an irritant and also flammable‚ therefore gloves and goggles should be worn at all times during the experiment. It is reactive to water‚ so in the case of fire‚ alcohol foam or carbon dioxide is preferred to use as an extinguisher. This chemical has harmful fumes and use of a fume hood is strongly recommended. Sulphuric and Salicylic Acid These acids may irritate the skin in high concentrations. Take

    Title: Surface Area vs. Rate of Reaction Research question: How can different temperatures affect the rate of reaction‚ when the reactant is in powder form? Hypothesis: If the temperature of the water is increased‚ the rate of reaction will also increase as the heat given off to the particles will increase leading to more movement and frequent collisions. Background information: Chemical reactions occur when two or more molecules interact with each other‚ but that can only occur when they

    on top of the shorter cup to prevent any heat loss to the air. Then the shorter cup was secured on a base with tape 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

    Flatland Reaction Paper Prior to reading this article‚ I never really thought of math to be this universal thing that could be applied over such a large horizon. I was knowledgable that‚ of course‚ everyone and everything could be eventually linked in some way or fashion to mathematics‚ but I was oblivious to how large of a spectrum it all really sits. Overlooking all of the sexist and biased opinions stated by Edwin A.Abott in this piece‚ he really opened my eyes to a different perspective of
