Answer:
1809.9 Grams of Calcium Nitrate
Explanation:
Calcium Nitrate Ca(NO3)2
Molar Mass: 164.086g/mol
Given: 11.03 mol of Ca(NO3)2 x 164.086g/mol = 1809.9 Grams of Calcium Nitrate
Answer:
E° = 2.46 V
Explanation:
We have a voltaic cell of aluminum and silver in their respective solutions. To know where will take place the reduction (cathode) and where will take place the oxidation (anode), we need to compare the standard reduction potentials.
E°(Al³⁺/Al) = -1.66 V
E°(Ag⁺/Ag) = +0.80 V
Since Ag⁺/Ag has the highest reduction potential that is where reduction will take place while oxidation will take place in the Al electrode.
Reduction (cathode): Ag⁺(aq) + 1 e⁻ ⇒ Ag(s)
Oxidation (anode): Al(s) ⇒ Al³⁺(aq) + 3 e⁻
The standard potential of the cell (E°) is the difference between the reduction potential of the cathode and the reduction potential of the anode.
E° = E°red,cathode - E°red,anode = 0.80 V - (-1.66V) = 2.46 V
Assuming the conditions of the reaction are maintained and appropriate for the reaction to still occur, the reaction rate can be affected by increasing the concentration of the reagents used in a reaction. It will speed it up.
It is O with a little 2 subscript. it represents two atoms of oxygen.
