One student filled two clean jars with hot water. Baking soda was added to water in both the jars and stirred until no more baking soda dissolved in the water. Small weights were tied to two ends of a thread and the ends were dipped into the two jars as shown below. (1 point) An illustration depicting two glass jars filled with water. A string connects the two jars. One end of the string is weighted and submerged in the first jar, and the other end is weighted and submerged in the second jar. A white material is seen to be growing down from the middle of the string and accumulating on a plate placed between the two jars. After two or three weeks the student observed a white solid material growing down from the middle of the thread between the two jars. The student's experiment demonstrates that

These questions are based on the attached photo. the experiment is about burning magnesium metal with oxygen. 1. write the balanced chemical equation for the reaction you are performing. 2. calculate the mass of magnesium metal used in each trial. o trial 1: o trial 2: 3. calculate the actual yield of magnesium oxide for each trial. o trial 1: o trial 2: 4. magnesium is the limiting reactant in this experiment. calculate the theoretical yield of mgo for each trial. o trial 1: o trial 2: 5. determine the percent yield of mgo for your experiment for each trial. o trial 1: o trial 2: 6. determine the average percent yield of mgo for the two trials. your company currently uses a process with a similar cost of materials that has an average percent yield of 91 percent. if the average percent yield of this process is higher than that, this could save the company money. what is your recommendation to the company? support your recommendation using your data, calculations, and understanding of stoichiometry gathered from this lab.
