Use general chemistry rules for significant figures. 1. (12 pts) A cell is constructed to reduce the Ag+ in AgCl(s) to Ag(s) at the cathode when
current is passed through the cell. At the anode, Cu(s) is oxidized to Cu2+.
If current of 0.500 A is passed through the cell for 101 minutes, calculate the mass of
Cu(s) dissolved and mass of Ag(s) deposited. Half-cell reactions:
Cathode: AgCl(s) + e ⇌ Ag(s) + Cl–
Anode: Cu(s) ⇌ Ce2+ + 2e

Look at the bean data from days 4–6. use these data to explain how natural selection changed the number of dark red walking beans over time. writing part

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.
