    This part of the experiment yielded an exothermic reaction. The purpose was to calculate the specific heat capacity and molar mass of the zinc metal. The specific heat capacity was found to be 0.197 J/g °C with a percent error of -49.5%. The molar mass was found to be 127 g/mol with a percent error of 94.2%. Possible sources of error inherent to this segment of the experiment were the fact that when the temperature of the solution was being measured

    Hydrogen peroxide and iodide ions Aim: To determine the rate equation for the reaction between Hydrogen peroxide and iodide ions‚ and to investigate the effects of a catalyst and temperatures on the reaction and to derive the activation enthalpy. Background knowledge: 1Hydrogen peroxide reacts with iodide ions producing iodine‚ when in an aqueous acid solution. H2O2 (aq) + 2I- (aq) + 2H3O+(aq)  I2 (aq) + 2H2O(l) To detect iodine you can look at the color shown by the addition of starch

    Lab 3: Hydrogen Spectrum Abstract When white light is viewed through a diffraction grating‚ we can see each component that makes up the light. However‚ when in an excited state‚ a gaseous element produces bright light of specific wavelengths rather than a continuous spectrum of colors. This phenomenon ultimately lead to the Neils Bohr model of the atom in 1913. Introduction In the middle of the 19th century‚ Robert Bunsen and Gustav Kichoff observed that gases emit spectral lines specific

    hydrogen chloride has properties: Hydrogen chloride has one molecule of hydrogen and one molecule of chlorine: Hydrogen chloride has a very powerful smell. It is in the form of a gas but only when it is at room temperature which is approximately 25 Celsius and when the pressure is high. The solubility of hydrogen chloride is very high this means that it can dissolve in water quickly because it dissolves many times in its own solution (the gas form of hydrogen chloride). It is very soluble because
