In this experiment, solid magnesium was conducted in a chemical reaction with hydrochloric acid solution. The three objectives include: measuring the gas production of a chemical reaction by a pressure change, determining the mass of the hydrogen gas produced in the reaction, and determining the effectiveness of the procedure by calculating the percent yield. In order to complete these objectives, a flask containing the magnesium ribbon was completely submerged into a large beaker filled with water. Next, hydrochloric acid was emptied into the flask using a gas syringe. Then, a Gas Pressure Sensor was used to measure the pressure in the sealed vessel, and a temperature probe was used to measure the temperature of the reaction indirectly by

The actual yield was used to find the mass of the hydrogen gas. This data can be compared to the theoretical yield to determine how well the experiment was performed. Additionally, the theoretical yield was used to determine the percent yield. The higher the percent yield, the better the experiment was performed. However, the percent yield from the two trials were low due to the errors that occurred throughout the lab. Another topic that relate to this lab was single replacement. In this experiment, solid magnesium and hydrochloric acid solution underwent a single replacement that yielded magnesium chloride and hydrogen gas. Additionally, the ideal gas law was used in this experiment to find the moles of hydrogen gas. Another topic that relate to this lab was the limiting reagent. The limiting reagent in this experiment was the magnesium. Additionally, the water vapor pressure was present during the experiment, which was used in the calculations. Another topic was the signs of a chemical reaction. The sign that a chemical reaction occurred was the formation of a gas which was determined by looking at the pressure increasing in the Gas Pressure Sensor. Additionally, the pressure change and partial pressure were related to the topics that have been taught in
