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
H66 I think oxygen it was that is
Answer:
Phosphorus atoms can bond with oxygen atoms to form ester groups. These can bond with carbon atoms, yielding a large number of organic phosphorus chemicals. These are found in many important biological processes
To convert grams to moles, we need the molar mass of carbon. this can be founded in the periodic table.
molar mass of C= 12.0 g/mol
38.1 g C (1 mol C/ 12.0 grams)= 3.18 moles of C
