Answer:
Numbers of electrons transferred in the electrolytic or voltaic cell is 6 electrons.
Explanation:


The substance having highest positive reduction
potential will always get reduced and will undergo reduction reaction.
Reduction : cathode
..[1]
Oxidation: anode
..[2]
Oxidation reaction occurs at anode and reduction reaction occurs at cathode.
To calculate the
of the reaction, we use the equation:


The overall reaction will be:
2 × [1] + 3 × [2] :

Electrons on both sides will get cancelled :

Numbers of electrons transferred in the electrolytic or voltaic cell is 6 electrons.
Answer:
1. Carbon dioxide, increase of green house gas
2. Stop deforestation, cut down amount of cars on the road (encourage public to take public transport), reduce the amount of time u on the air-conditioning
The level of toxins in the fish's cell is equivalent to the level of toxins in the water. Therefore, in order to reduce the toxins further, we should replace the now contaminated water with clean water. After the level of toxins in the fish's cell stops reducing, we replace the water with clean water once again.
B ia the correct one .
Hydrogen only uses the first energy shell, which holds 2 electrons, not 8.
