...0.............I..V.-II..............II...V.-II...........II..-II.......I...-II
3Cu(s) + 8HNO3 ---> 3Cu(NO3)2 + 2NO + 4H2O
V.....................II
N + 3e -----> N >> reduction
HNO3 - oxidizing agent
..0...........II
Cu ----> Cu + 2e >> oxidation
Cu - reducing agent
Row or periods have in common is the valence electron count. The valence electron count goes up as you move across the periodic table. Also atomic size gets smaller as you move from left to right
Answer:
box a is warmer than box b, so the molecules are moving around a lot more
Answer:
1st:Make an observation
2nd:Ask a question
then you can make a hypothesis
In a voltaic cell, electrons flow from the anode to the cathode. Anode is negative while cathode is positive.
In an electrolytic cell, electron flows from the cathode to the anode. Anode is positive and cathode is negative.
For both, Oxidation occurs at the anode and Reduction occurs at the cathode.
