What is the maximum number of electrons that can be placed in the first shell/energy level?
A. 1
B. 8
C. 2
D. 18
Answer:
D. 18
Explanation:
Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on.
The students on the right are applying a force of 100 N to
the right. This is shown by the red arrow. The students on
the left are applying a force of 100 N to the left. This is
shown by the blue arrow.

Blue team
Red team
Which action is most likely to make the team on the left win?
A. Adding one student to the team on the right
B. Instructing both teams to pull a little less so that each side is
applying only 50 N of force
C. Adding one student to the team on the left
D. Instructing both teams to pull harder so that each side is applying
150 N of force
Answer: C) adding a person on the left
This additional person will pull more force to the left side and help that team win the tug-of-war.
Choice A is the complete opposite of what we want, since it helps the red team win. Choices B and D won't change the current state because the same thing is happening to both sides. So we can rule out choices A, B and D.

How do electronegativity, polarity, and ph all relate and effect each other? I know moderators, you will be reported if you give a link or wasteful answer.
Answer:Electrons in a polar covalent bond are shifted toward the more electronegative atom; thus, the more electronegative atom is the one with the partial negative charge. The greater the difference in electronegativity, the more polarized the electron distribution and the larger the partial charges of the atoms.

Item 5 What is the role of a generator in producing electricity? The generator stores electrical energy for later use in homes and businesses. The generator spins the turbine to create mechanical energy. The generator transforms the mechanical energy of the turbine into electrical energy. The generator reverses the turbine to create electrical energy.
Answer:
The generator transforms the mechanical energy of the turbine into electrical energy
Explanation:
Electricity generator is a device that is used in generating power supply which can be used in industries, homes and for commercial and private purposes.
It operates by converting mechanical energy into electrical energy for the use in an external circuit. mechanical energy can be obtained from steam turbines, internal combusting energy, gas and water turbines and it can be obtained through the rotating shaft.
The capacity of each generator determines the amount of energy it can supply to a given place.
