    Decomposition of Sodium Chlorate Mass‚ Moles‚ and the Chemical Equation Introduction: Sodium chlorate is used as a source of oxygen in emergency oxygen generators. So-called oxygen canisters or oxygen candles are found on airplanes‚ submarines‚ even the space station–anywhere where oxygen might be in short supply in case of an emergency. Sodium chlorate decomposes upon heating or in the presence of metals to give oxygen gas. What the chemical equation for the decomposition of sodium chlorate?

    The purpose of this experiment was to determine the speed at which a reaction took place between an iodine and hydrogen peroxide solution. In addition to a change in concentration‚ a change in temperature and a catalyst variable was also introduced to conclude whether or not their presence affected the overall speed of the reaction. In order to determine the effects of these variables‚ several iodine and hydrogen peroxide reactions were prepared‚ (all at varying temperatures‚ volumes‚ and concentrations)

    It was originally hypothesised that the reaction time would decrease with higher concentrations of the reactants‚ potassium iodate and sodium bisulfite as collision theory stated that more molecules present in a given volume meant a greater chance they would collide. Furthermore‚ the time was expected to decrease with higher temperatures as it influenced the reactant particles by raising their kinetic energy. However‚ the data collected from this experiment only partially supported this hypothesis

    t-Pentyl Chloride is a compound that is created through an SN1 nucleophilic substitution reaction in addition with Hydrogen Chloride in order to isolate the product. A variety of procedural techniques were utilized during the experiment including extraction‚ washing liquids‚ drying liquids‚ gravity filtration‚ and simple distillation. When a single solute or compound is transferred between two different solutes‚ it is known as extraction. Another technique that was utilized was washing‚ in which

    In this experiment‚ the objective is to successfully perform an SN1 reaction to determine the reactivity of tert-butyl chloride‚ through the usage of sodium iodide/silver nitrate reagents and to synthesize tert-butyl chloride. The tert-butyl chloride was synthesized through the use of separation (aqueous and organic layers) and distillation. Tert-butyl chloride is the alkyl halide which is being synthesized throughout the course of the experiment. Alkyl halides are derived from alkanes. Once an alkane
