Benzoic acid was mixed with methanol and heated under reflux. The reaction mix was extracted with dichloromethane and washed with sodium carbonate solution, then washed with saturated sodium chloride solution. After being dried over magnesium sulfate, the solvent was distilled off to yield the ester product, methyl benzoate. Drag and drop the chemical wastes generated in this reaction into the appropriate container.

1. list three scientific reasons cockroaches may fly.

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.
