Half Reactions Help Please?

So I'm a little confused on whether or not you add the coefficient when you write the half reactionsFor example:3Cu^+2(NO3)2^-1 + 2Al 2Al^+3(NO3)3^-1 + 3CuThe copper would be reduced because it lost electrons and aluminum would be oxidized because it lost electronsWould the half reactions of copper be 3Cu^+2 + 3e^-1 3Cu or Cu^+2 + 2e^-1 Cu?Also, for aluminum, would it be 2Al 2Al^+3 + 4e^-1 or Al Al^+3 + 3e^-1? Thanks~

Answer:

I second briningMy hubby started doing this a few years ago, and it makes a huge difference in the texture, moisture of the meatAlso - a aluminum foil shield can protect the breast meat as the dark meat finishes cookingHope it comes out well:)
If you do not have a rotisserie, brine the turkey overnight:) Season w sugar, add water to moist:) Place in fridge at least 24 hoursOlive oil, lemon and herbs works just as wellBeer is niceSoy sauce and garlic:)
Well first, cook for the recommended time, don't overcook itBefore cooking, coat with 1/4 cup olive oil, 1 tbsppaprika, 1 tbsp minced garlic and any spices you like, such as rosemary, tarragon, mace, etcThat will make it brown nicely Cook until the top starts to look quite brownm then tent the top with aluminum foil and continue cooking.
The most important thing is to use an oven bag.
The 1 on a -1 is understoodThis half-reaction for copper: Cu^+2 + 2e^- Cu For aluminum: Al Al^+3 + 3e^- BTW, in your other two possible answers: 3Cu^+2 + 3e^-1 3Cu 2Al 2Al^+3 + 4e^-1 the charges do not balance.
