2. calculate the standard emf of a cell that uses the mg/mg+2 and cu/cu+2 half-cell reactions at 25ºc. write the equation for the cell reaction that occurs under standard-state conditions. (10 points)

2.71 V

Explanation:

Usually in the cell notation, the left side shows oxidation. So,  

Oxidation half reaction:

Reduction half reaction:

Overall reaction:

b.

the accuracy of the data.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
