SC.912.L.17.8 Florida's ever growing population has been a concern for the biodiversity of our state's
natural ecosystems. People have been interacting with nature for thousands of years,
but since the twentieth century biodiversity has been reduced at an alarming rate.
Which human practice has NOT been a related concern for the reduction of biodiversity
in our state's forests, prairies, swamps, lakes, streams, and reefs?
O developing millions of acres of land for agriculture purposes
drainage of wetland areas in the south
authorization of prescribed burns in land management areas
O urbanization along the coastal areas

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.
