Free Response Question 4: Aqueous silver nitrate reacts with aqueous magnesium iodide to form solid silver iodide and aqueous magnesium nitrate. Write a complete and balanced chemical reaction. Include the phases for each compound. If the solutions contained 50.0 grams of silver nitrate and 50.0 grams magnesium iodide, determine which reactant is the limiting reactant and how many grams of precipitate are produced (In other words, what is the theoretical yield of the precipitate)? A student carried out the experiment and produced 48.3 grams of the precipitate. Calculate the percent yield for the experiment.

Please ensure that your camera is set up to show your workspace and your face. At this time show the front and back of your scratch paper, periodic table, and naming compounds and solubility rules chart to the camera so I can see that they are not written on. Also show your calculator so I can see the type of calculator you are using. Please keep your hands visible in the camera. I understand that they may be out of view when reaching to move to the next question or to use the online calculator but please keep them above the table and do not reach off to the sides.  Now answer the following true or false question to earn a bonus point: I have done the above requirements, read the exam and Honorlock instructions, and understand that failure to follow all instructions will result in a zero on my exam.
