A student was investigating cooling times for two pots made of different materials. One-pot was stainless steel and the other pot was
iron. The pots were placed on a table in a 25°C room. The pots and water
were originally at 100°C. The student recorded the temperature of the
water in each pot over time. The graph below shows the results. a.
Determine the amount of time it took the water in the iron pot to cool
from 100°C to 60°C. b. Based on the graph, which pot, the iron pot or the
stainless steel pot, was a better conductor of thermal energy? Explain
your answer. c. Identify two methods of heat transfer that occurred as
the water in the pots cooled, and describe how the transfer of heat
occurred for each method. d. Describe when the pots no longer
experienced a net loss of thermal energy.

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.
