<span>Answer:
Zn(2+) + 2e(-) -------> Zn
1 mole of Zn is deposited by 2F of electricity ...
so 48.9 mole of Zn will be deposited by 48.9 X 2F = 97.8 F of electricity...
as 1F = 96500 C
so 97.8 F = 97.8 X 96500 = 9437700 C of electricity...</span>
Answer:
Copper
Explanation:
Metals are often arranged in crystalline lattices. The lattice consists of metal ions with an overlying sea of electrons. The conductivity of a metal depends on the nature of this crystal lattice. Naturally, some metals conduct electricity better than others. The unique properties of the crystal lattice of copper allow electrons to flow through it freely especially when it is drawn into a wire.
Answer: MgAl2O4 or Spinel (gemstone)
Explanation:
1. 1.35 atm to psi = 19.83953 psi.
2. 100.2 kPa to mm Hg = 751.5617 mm / 29.589043 Hg
3. 10.83 psi to kPa = 74.670221 kPa
