Answer:
inner energy shells are involved in radioactive activity
1 mole F=19g
2.47 moles F=2.47*19=46.93g
Carbon- 0.27/0.45 = 0.60*100 = 60%
Hydrogen- 0.020/0.45 = 0.04*100 = 4%
Oxygen- 0.16/0.45 = 0.36*100 = 36%
An electrode is strip of metal on which the reaction takes place<span>. In a </span>voltaic cell, theoxidation<span> and reduction of metals occurs at the electrodes. There are two electrodes in a </span>voltaic cell, one in each half-cell<span>. The cathode is where reduction </span>takes place<span>and </span>oxidation takes place<span> at the anode.
So, the answer is A. anode
Hope this helps:-)

Calcium has electrons in more energy levels than magnesium. The number of electron in calcium atom is 20 which means 4 energy levels. (2 electron in first shell+ 8 electron in second shell+8 electron in third shell+ 2 electron in fourth shell). While number of electron in magnesium atom is 12 which means 3 energy levels. (2 electron in first shell+ 8 electron in second shell+ 2 electron in third shell). Also the Calcium third energy level contains more electron than magnesium.
