Create a graph to compare the actual temperature changes over time using your spreadsheet. The steps involved in creating your graph will be different depending on your software. For most platforms, it’s necessary for the two columns you’re correlating to be next to each other. Use the cut, copy, and paste features to relocate the anomaly values so that the actual temperatures are in column B next to the years in column A. Highlight columns A and B. From the menu, choose Insert and select the graph or chart type you decided on in part D. If needed, update the graph and axis labels so that it is easy to tell what the graph is displaying. Capture and save an image of your graph. Use the insert Image button to add the image to the answer space.

In order to calculate the amount of heat transferred you must know the __ and specific heat of the material, as well as the change in temperature. a. volume b. density c. mass d. enthalpy

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.
