Answer:
between the 2 and the 3 shell
Explanation:
when a gain of energy is the displacement of the electrons in a layer of low-energy shell high-energy, and here we have the 2nd shell is the shell of low energy, and 3 shell the shell is high-energy.

Answer:
A solution is a heterogeneous mixture
Explanation:
This statement that a solution is a heterogeneous mixture is completely and totally wrong.
A solution is a homogeneous mixture.
Homogeneous mixtures have their constituents existing in just one phase.
- It is a homogeneous mixture of solutes and solvents.
- In a solution, the solutes particles are distributed uniformly in the solvent.
- The solute is the substance that is dissolved to make the solution.
- Solutes are usually present in a small amount than the solvent.
- The solvent acts as the dispersing medium which allows the solute to go into the solution.
- The solute can be solid, liquid or gas.
Answer:
$200.0 is the cost for installing a carpet for a room that measures 12.0 feet by 15.0 feet.
Explanation:
Length of the room = l = 15.0 ft = 
Width of the room = w = 12.0 ft = 
(1 yard = 3 feet)
Area of the room = l × w = 
Cost for installing a carpet for a room = $10 per square yard
Cost for installing a carpet for a room wit area 20.0 square yard :
$200.0 is the cost for installing a carpet for a room that measures 12.0 feet by 15.0 feet.
The correct option is C.
A Lewis dot diagram is a representation of the valence electron of an atom, which uses dot around the symbol of the atom. Chlorine has seven electrons in its outermost shell, these seven electrons are arranged in form of dot around the atom of chlorine. If you count the number of dot given in option C, you will notice that they are seven.
