The graph above gives the land surface air temperatures and the sea surface water temperatures from 1950 to 2016 . Global warming encompasses the changes in climate and temperature around the globe from the oceans to on land. However, when studying the warming of earth’s land and water temperatures a difference between the two can be observed. From the graph it can be seen along most of the graph that the water temperature of the sea’s surface remained lower than that of the land’s surface air temperature. What unique characteristic of water allows for this phenomenon to occur?

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.
