Answer:
290 N
Explanation:
Total downward force = Force applied on the door in bringing it down + weight of the door
Total downward force = 80 + 210
Total downward force = 290N
C: Lithium. Before it was 4Li and after the oxidation it turned out to 2Li
Answer: Work was 15 Joules
Explanation: Work W = force F · distance s
W = 5 N · 3 m
Answer:
C. Oxidation occurs at the anode and reduction occurs at the cathode.
Choice number third is the correct option for the given question
Explanation:
Copper and silver nitrate are the two components that form a voltaic cell. These are the two main ingredients which make the Redox reaction possible. The dog reaction that is taking place result in development of charge.
Since copper here is the anode in the reaction oxidation happens here by the solution
is cathode this is where reduction takes place.
