I don't need anyone to do my homework for me, I just need help. My teacher gave us homework from a chapter that we have never talked about, I need help understanding it.
Balance the following equations, and identify the oxidizing and reducing agents.
A) NO2 (-) + Cr2O7 (2-)= Cr (3+) + NO3 (-)
B) As + ClO3 (2-)= H3AsO3 + HClO
I figure that if someone can explain these two to me, so that I understand, I can get the rest on my own. Please help, I have read the whole chapter and I still cant figure these ones out, and my teacher is out of town and can't help me but the sub is collecting it. Thanx
