Question

Need fill ins for these impossible questions ASAP!

1.
Question 1 (15%): How do you balance a half-reaction if one side doesn't have hydrogen?

Question 2 (15%): How do you balance charge for a half reaction?

Question 3 (70%): Create your own steps on how to balance a redox reaction. You may use the steps that I used in the video to help you out with making your own steps. Here are the following items that must be included:
Explain how to know if a compound can be separated into ions.
Explain why the assigning of oxidation numbers is needed at the beginning of the steps.
Why water is used to help balance oxygen.
Explain why the oxidation and reduction half-reactions must have the same amount of electrons.
Balance the following formula using your steps:
CuS (aq) + HNO3 (aq) → Cu(NO3)2 (aq) + NO (g) + S (s) + H2O (l)
