<span>1) The charge of copper on the reactant side is 0 (it is solid copper thus not charged).
2) The charge of the copper ions on the product side is 2+ (when ionized it is evident that Copper in Copper Nitrate is in its 2+ form)
3) Copper was Oxidized since its oxidation state increased from 0 as a reactant to +2 as a product
4) The number of electrons transferred is 2 electrons. Since oxidation is the loss of electrons, then Copper lost 2 electrons.

Answer:
2, distilling
Explanation:
Distilling two liquids is much easier than any other listed way.
2 moles Na ------> 1 mole Cl2
4 moles Na --------> ?
Moles of chlorine:
4 * 1 / 2
4 / 2 =
2 moles of Cl2hope this helps!.
Answer:
0.1933 M
Explanation:
Data provided in the question:
Number of Moles of Na₂SO₄ initially taken = 0.145 mol
Volume of solution, V = 750 mL = 0.750 L
Now, the molarity is given as:
Molarity = 
or
Molarity = 
or
Molarity = 0.1933 M
