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.

In this problem, you will determine the biosynthetic cost of generating the amino acid serine from glucose used as food. the biosynthetic costs of all the amino acids are given in table 5.1, and now you will get a first-hand sense of how to obtain those values. visit the website and find the metabolic pathways for serine synthesis and glycolysis. the starting molecule of the serine synthesis pathway is an intermediate in glycolysis. how many molecules of glucose must be taken up to provide the carbon skeleton used to make serine? draw the biochemical pathway starting with glucose and ending in serine, labeling the energy-requiring and energy-generating steps. how many molecules of atp are consumed and created along the way? how many reducing equivalents of nadh and nadph are consumed or created along the way? in order to answer this question completely, you may need to consider a few other pathways as well. for example, it is likely that the displayed glycolysis pathway does not actually start with glucose. to get glucose 6-phosphate from glucose requires 1 atp. one of the steps in the serine synthesis pathway is coupled to a conversion of l-glutamate to 2-ketoglutarate.

Was there supercooling? would you expect the water or the sugar solution to have the most supercooling? why?
