Multiple Choice Which of the following statements explain how
this experiment relates to the cycling of
matter?
Elodea uses water and carbon dioxide to
produce glucose and oxygen. The snail
uses glucose and oxygen and produces
water and carbon dioxide.
Elodea uses light, oxygen and water to
produce glucose. The snail eats the
elodea and releases carbon dioxide as a
waste product
The snail performs photosynthesis which
C releases carbon dioxide into the
atmosphere.
Nitrogen-fixing bacteria remove ammonia
D from the testube and increases dissolved
oxygen.

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.
