Explanation:
96.485 columbs=1 faraday will
deposit 64/2g= 32 g cu ion
therfore it will require
96,485 ×2/32 =? coulombs or 1/16 of
Faraday= 1 / 16 mole of electrons .
If the resources run out and there is no way to get them all motors will have to be switched to solar or some other source.

Answer : The balanced reaction in acidic solution is,
Explanation :
The given partial equation is,
First we have to separate into half reaction. The two half reactions are:
Now we have to balance the half reactions in acidic medium, we get:
............(1)
............(2)
Now we have to balance the electrons of the half reactions. When we are multiplying the equation (1) by 2, we get
...........(3)
Now we have to add both the half reactions (2) and (3), we get the final balanced chemical reaction.
Hydrogen reacts with water according to the following equation:
2H2 + O2 ..............> 2H2O
From the periodic table:
molar mass of hydrogen = 1 gram
molar mass of oxygen = 16 grams
Therefore:
4 grams of hydrogen react with 32 grams of oxygen to produce 36 grams of water vapor.
Now, we need to determine the limiting reactant in the equation. By comparing, we can deduce that hydrogen is the limiting reactant (<span>because half of that amount is less than how much O2 you have).
This means that, once the amount of the reacting hydrogen is consumed, the reaction will stop. So, our calculations will be based on the amount of reacting hydrogen.
Now, back to our calculations:
we know that 4 grams of hydrogen are needed to produce 36 grams of water vapor.
To know how many grams of water vapor were produced from 1.8 grams of hydrogen, we will use cross multiplication as follows:
mass of water vapor = (1.8 x 36) / 4 = 16.2 grams</span>
