How much Gas is Preduced - Essay ExampleThe reaction coming back as followsIn this essay whizz notify see that two gram molecules of HCl react with one mole of magnesium to produce one mole of each MgCl2 and H2. Since the product H2 is gaseous in nature, one can safely assume that if the reaction proceeds at standard temperature and pressure (273K, 1 atm) the volume of one mole of H2 produced will be 22.4 litres. Also, one mole of Magnesium will have the mass in grams equal to its molecular weight i.e. 24. Therefore, the mass of magnesium used in the reaction can be converted into the number of moles of magnesium used in the reaction, for e.g. The Pressure sensor was used in the audition to calculate the pressure at which the volume of gas was to be computed. Other equipments used in the experiment were weighing balance, tongs, measuring cylinder, flask, test tubes, stop-cock, glass-tube etc. The materials used in conducting the experiment were moderately diluted HCL and pulve rize Magnesium. The diagram of the apparatus is given as followsThe mass of Magnesium used in the reaction is metric by the weighing scale and the volume of HCL is measured by the measuring cylinder keeping in mind that the pressure required is 0.5 atm. The dit is sufficiently diluted so as to have a smooth reaction as the reaction between Hydrochloric Acid and Magnesium is exothermic i.e. a muddle of heat is evolved. Also the gas produced Hydrogen creates a lot of fizz in the flask. When combining the reagents into the flask, business concern must be taken that none of the gas being produced escapes when adding the reagents together, before sealing the container. Therefore, we add hydrochloric acid in the flask first followed by Magnesium and instant sealing of the flask so as to prevent the escape of any hydrogen gas. The gas is attached to a pressure sensor by a glass tube which records the pressure
