Experts, students me with the 11th question a$ap if u answer this u will gain 25 points

-

Carbon cannot reduce sodium, magnesium and calcium to their respective metals because carbon is lower than them in the electrochemical series.

Only metals higher in the electrochemical series can displace metals placed lower.

Sodium, magnesium and calcium are obtained from their salts by electrolysis of the salts.

Sodium Chloride is the sodium salt used. Sodium is deposited at cathode.

Chlorine gas is produced from the process.

Cathode: 2Na+ + 2e- --> 2Na (Reduction)

Anode: 2Cl- --> Cl2 + 2e- (Oxidation)

Potassium and Calcium are two other metals that can be extracted by the same method

i believe it is a.) released into

explanation:

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 : )
