Answer:
The answer will be 160 we have to just multiply it ok
Answer:
Rubber is an insulator.
Remaining three are metals and hence conductors.
Answer:
Attractive force is predominant between the two atoms
- The two hydrogen atoms approach each other to form a bond
- The two hydrogen atoms start to combine to form a hydrogen molecule
Repulsive force is predominant between the two atoms
- The potential energy of the system is positive
- The internuclear distance between the two hydrogen atoms is less than the bond length
Attractive and repulsive forces balance each other
- The two hydrogen atoms form a stable hydrogen molecule
- The potential energy of the system is at minimum
There is no interaction between the two atoms
- The hydrogen atoms are very far apart
Explanations:
- <em>increase in potential energy causes repulsion</em> between the atoms, whereas<em> decrease in potential energy causes attraction</em> between the atoms
- in order for the bonding to occur, the attractive forces must be greater than the repulsion forces.
- The potential energy is positive when the repulsion forces is greater. This is because the distance between the two atoms is smaller than the bond length
- The potential energy of the system is at its minimum because the attractive and repulsive forces balance out each other.
I am not sure but if you google the question it brings up a table :P
