Are the following Redox reactions or non-Redox reactions? If you determine that they are Redox, state which reactants have been Oxidised and which have been Reduced? Also remember to assign oxidation numbers for all atoms or ions on the reactant and product side to denote electron transfer for reactions identified as Redox. i) ii) Zn(s) + CuSO4(aq) → ZnSO4(aq) + Cu(s) NaOH(aq) + HCl(aq) → NaCl(aq) + H₂O (1)

You are asked to determine the percentage of the components of a mixture containing sodium iodide, NaI, magnesium hydroxide, Mg(OH)2, and barium sulfate, BaSO4. The total mass of your mixture sample is 4.82g. First you extracted the NaI from the mixture with water and filtered insoluble Mg(OH)2 and BaSO4 from the solution, containing the NaI. After evaporating and drying the filtrate, you find that you have recovered 0.95g of NaI. When you react the insoluble residue of Mg(OH)2 and BaSO4 with 3M HCl, the Mg(OH)2 dissolves. After decanting the supernatant liquid containing aqueous MgCl2 from the insoluble BaSO4 and drying the solid, you recover 2.04g of BaSO4. Finally you add 3M KOH solution to the aqueous solution to precipitate the Mg(OH)2. After filtering thesolution and drying the precipitate, you recovered 1.21g of Mg(OH)2. Calculate the percent Mg(OH)2 in the original sample mixture.
