Your task:
Create a lab report for the following virtual lab activity. You will not have to work with chemicals, instead the lab will be focusing on analyzing the results of an activity theoretically. For your report, you should include the following:
• Title page
• Purpose
• Results
• Calculations
• Three sources of error
• Conclusion
You can include the information for the lab provided below by copying and pasting into your report. Use the questions given under the Results and Calculations headings to guide your analysis.
Heat of Reaction for the Combustion of Magnesium
Although you will not be working with actual chemicals during this laboratory, since you will be doing it virtually, the procedure is given in order for you to be aware of the process that would be followed in a laboratory setting.
Introduction
In this experiment, you will use Hess’s Law to determine the heat for a reaction that is difficult to measure directly. Magnesium metal burns rapidly, releasing light and heat, as observed in photo flashbulbs or by burning magnesium ribbon. The reaction is presented by the equation:
Mç^ + tf02(8) > MgO(i) (1)
This equation can be obtained by combining equations (2), (3) and (4):
MgO)t) + 2HCU – ) MgCI2(aq) + ha, (2)
+ 2HCU – > MCjQjtjq) + n^cg) (3)
H«,, + KOw? ? * HA> (4)
By combining these three equations, you can obtain equation (1). The heats of reaction for equations (2) and (3) can easily be determined by experiments. The heat of reaction for equation (4) can be obtained from a table of values for previously measured reactions.
