Abstract: Using the chemical equation we can study the reaction taking place between magnesium metal and sulfuric acid in solution. The = for the reaction of sulfuric acid and magnesium metal.
Introduction
This report demonstrates calorimetry, or the technique of measuring heat effects in the surroundings. In order to make sure that there is no temperature change, or that it is an isothermal heat transfer, it is kept at a similar temperature in an ice bath. By knowing the change in volume, the density of ice, and the density of liquid water, it is presumed that then you could decipher the mass of the ice that melted. With this, it is possible to understand the transfer of heat from this chemical equation to its surroundings. As the chemical reaction gives off heat and energy to its surroundings, it is an endothermic reaction. This means that it will have a positive change in H.
Methods
First, test the calorimeter apparatus to make sure that it is working properly without any substantial leaks. Then, fill the calorimeter with crushed ice, and cool water till it is full to the brim. Then, place the …show more content…
The first time, the two of us did not go long enough in order to see the upward curve signifying the end of the chemical reaction. The second time, the results were taken long enough to show a slow stop of the reaction, but it was still had error. There had been no ice put into the apparatus, so it was impossible to accurately record the correct change in volume due to the heat of the reaction. After these two inadequate attempts, we are now using sample data to show the correct process and results. Also, there could have been heat escaping from the experiment the whole time we were recording data, especially as the chemical reaction was underway. This could ruin the
