Investigation of Enthalpy Change When Mg is added to HCl Essay

Research QuestionHow is the enthalpy change of the reaction between Mg and HCl moved(p) when contrary lists of Mg are added to a perpetual amount of HCl?VariablesIndependent MgDependent TemperatureControl HClControlling VariablesI provide use three diametric masses of Mg 0.02g 0.001g, 0.03g 0.001g, 0.04g 0.001gI will footprint the temperature using a colorimeter made from a foam form, a lid, and a thermometerI will keep HCl at a constant volume of 10mL of 1M HClProcedureStep 1 Measure out 10mL of 1M HClStep 2 Pour HCl into foam cup and place lid on cupStep 3 Measure the initial temperature and record dataStep 4 Add in 0.02g of Mg into cup and measure the finial temperatureStep 5 Calculate change in temperature by subtracting the initial temperature from the finial temperatureStep 6 Repeat steps 1-5 8 much times for a total of 9 trails changing the mass of Mg in step 4 every 3 trails from 0.02g 0.001g to 0.03g 0.001g to 0.04g 0.001g.Conclusion and EvaluationThe results portrayed a small correlation between the enthalpy change in the reaction between Mg and HCl when different amounts of Mg are added to a constant amount of HCl. The average enthalpy change of the different masses of Mg are not consistently changing. When the amount of Mg shifts from 0.02g 0.001g to 0.03g 0.001g the average enthalpy changes from 453.27 kJ/ mole to 406.77 kJ/mol but when it shifts form 0.03g 0.001g to 0.04g 0.001g the average enthalpy changes from 406.77 kJ/mol to 418.4 kJ/mol. Now the answer to the question -How is the enthalpy change of the reaction between Mg and HCl affected when different amounts of Mg are added to a constant amount of HCl? Is there is an effect to the enthalpy change when different amounts of Mg are added but it is unpredictable and the change in the enthalpy isnt steady in its rise or decline.The experiment was done using different foam cups and a calorimeter and the amount of time that the chemicals temperatures were recorded were diffe rent. If I was to improve this experiment I would use the same kind of foam cups and lids for each trial and I would also measure the temperature for each chemical under a specific time limit which would be the same for each trial.Investigation of Enthalpy Change When Mg is added to HCl
