Answer:
A: Cu; B: Mg; C: Mg + Cu²⁺ ⟶ Mg²⁺ + Cu
Explanation:
The left-hand side of the cell diagram is where oxidation occurs (the anode).
Mg ⟶ Mg²⁺ + 2e⁻
So, Mg is the anode.
The right-hand side of the cell diagram is where reduction occurs (the cathode)
Cu²⁺ + 2e⁻ ⟶ Cu
As the copper ions hit the copper cathode, they remove electrons from the metal and become copper atoms. Since the metal has lost electrons, Cu is the positive electrode.
To get the overall reaction, we add the two half-reactions,
Mg ⟶ Mg²⁺ + 2e⁻
<u>Cu²⁺ + 2e⁻ ⟶ Cu </u>
Mg + Cu²⁺ ⟶ Mg²⁺ + Cu
D melting ice cream because if u know what a physical change is its a change that you can reverse chimical change are changes you cant reverse so u can freeze back ice cream so :D
I believe the correct response is A. Wax which is made out of atoms that share electrons equally. Waxes being examples of lipids are primarily long chains of hydrocarbons consisting of carbon and hydrogen. And unlike polar and ionic substances, water molecules can not dissolve by attracting these fixed structures with equal electron densities to their respective partial charges.
