Answer:
The pencil box is too far away from the magnet to make it move.
Explanation:
The most likely scenario here is that the pencil box is too far away from the magnet to make it move.
A magnet has a force field around it which dictates the region where magnetic influences can be felt when a magnetic body is brought near it.
Outside the force field, a magnet has no effect on a magnetic body.
- Since the magnet is not attracting or repelling the metallic box of pencils, they most be located outside the field of force of the magnet.
- When they are within the force field, repulsion or attraction occurs and the field draws the metal to itself or repel.
Objects that are far away from a magnetic source will feel no effect of the force field of a bar magnet.
In this reaction, Copper is the element being oxidized because it is losing electrons. It starts with a neutral charge (0) and ends up with a 6+ charge. Because its charge is increasing, it is being oxidized (losing electrons).
Answer:
The correct option is a.
Explanation:

125 kPa
125kpa - 2x 4x x
Total pressure after reaction = 176 kPa
125 kPa - 2x + 4x + x = 176 kPa
x = 17
125 kpa - 2x = 125 kPa - 2(17) = 91 kPa
Initial pressure of the dinitrogen pentoxide ,(at t=0) =
Final pressure of the dinitrogen pentoxide, (at t = t) = P = 91 kPa
The rate constant is = 



It will take 113 minutes for the total pressure to reach 176 kPa.
