Using the Iodine clock method to find the order of a reaction Introduction When peroxodisulfate (VI) ions and iodide ions react together in solution they form sulfate (VI) ions and iodide. This reaction is shown below: S2O82-aq+ 2I-aq SO42-aq+ I2(aq) The reactants and the sulfate (VI) ions are colourless however the Iodine is a yellow/brown colour. This allows you to measure the progress of the reaction through the colour change when the iodine is produced. In order to determine the order of

EFFICIENCY INCREASING SYSTEM BY USING PREHEATING METHOD EFFICIENCY INCREASING SYSTEM BY USING PREHEATING METHOD METHODOLOGY The concept of increasing the fuel efficiency of a petrol engine in this project‚ is to pre-heat the intake air which is flowing through the carburetor. The humidity in the atmospheric air affects the petrol vapourisation in the carburettor. Therefore‚ by pre-heating the inlet air to the carburettor for a considerable amount‚ the vapourisation can be ease and in turn

Lab: Spectral Analysis Analysis 1. What causes each line to appear? Each line is able to appear because an excited electron was unstable and had to fall back to a more stable energy level‚ creating energy in the form of light. However‚ to understand this‚ one must understand what causes an electron to be excited. So from the very beginning‚ a person named Max Plank proposed a theory that energy is emitted and absorbed in quantities called “quanta.” Einstein then came along and said that light
