Answer:
Explanation:
Hello!
In this case, since the reactions between NaOH and the acids are:
Whereas we can see the 1:1 and 2:1 mole ratios between NaOH and HCl and H2SO4 respectively. In such a way, at the equivalence point we realize that:
Best regards!
There is 1 mole of electrons = 96500C and Ca = 40
Ca2+ + 2e --->Ca
Base on the formula above it means that there are 2 moles of electrons to produce 1 mole of calcium.
96500C x 2 = 193000C
193000C electricity produce 40g Calcium
Coulombs = Amps x seconds (28.70A for 12 hours)
= 28.70A x 12 x 60 x 60 C
= 1 239 840 C
This amount of electricity will produce
=1239840 / 193000 x 40g Calcium
= 6.42 x 40 g Calcium
= 256.96 g
So there will be 256.96g of Calcium metal that will be produced in 12 hours.
