Select the statement(s) that are correct with respect to waste disposal in the Electrochemical Cells Experiment. (Select all that apply.)
A. Rinsings from the half-cell module can be flushed down the sink.
B. The contents of the half-cell module should be disposed of in the waste container in the hood.
C. No waste will be generated during this experiment.
D. Dilute copper and ascorbic acid solutions should be disposed of in the waste container in the hood.
E. The electrodes should be discarded in the proper jar.
F. Metal and graphite electrodes should be rinsed with water, dried, and returned to their positions on the lab bench.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-

your answer is c) plasma

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools
