Six grams vegetable oil and a magnetic spinning vane are added to a conical vial. Before attaching a water-cooled reflux condenser to the vial, you will need to add ethanol and 0.20 grams potassium carbonate prior to refluxing your biodiesel synthesis. How many milliliters of ethanol do you need initially to get this reaction started? Assume that the oil requires 3X ethanol in excess per ester group to run a successful reaction. (Average molecular weight per triglyceride molecule of vegetable oil = 990.0 g/mol). Report to 3 sig figs.

Which statement describes both homogeneous mixtures and heterogeneous mixtures?

If 22.5 liters of oxygen reacted with excess of hydrogen, how many liters of water vapor could be produced?

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.
