Answer:
2n^2 electrons
Explanation:
for example, the first level contain 2*(1^2) = 2 electrons, the second level contain 2*(2^2) = 8 electrons, etc
Answer:
32
i just looked it up honestly
True. The balanced equation: 2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O represents the combustion of ethane (C₂H6).
A substance (often a hydrocarbon) combines with oxygen (O₂) in a combustion reaction, resulting in the major byproducts of carbon dioxide (CO₂) and water (H₂O). According to the equation, four molecules of carbon dioxide (CO₂) and six molecules of water (H₂O) are produced when two molecules of ethane (C₂H₆) and seven molecules of oxygen (O₂) react.
The number of atoms in each element is equal on both sides of the reaction arrow, indicating that the equation is balanced. This guarantees that the law of conservation of mass—according to which, in a chemical reaction, mass is never created nor destroyed—is upheld.
In conclusion, the combustion of ethane is accurately represented by the following balanced equation.

2C2H6 + 7O2 → 4CO2 + 6H2O
C2H6 is ethane,
Ethane reacts with oxygen, so it is the combustion.
The equation is balanced.
Answer is True.

Explanation:
Benefits of friction.
1. Walking. Friction between the soles of our shoes and the ground enables us to walk. The sole of the shoe is held to the ground through friction. This is what is termed as "grip" of the shoe. The more grip a shoes offers, the better and faster we can walk.
2. Writing. Writing using a pen requires friction. It is impossible to hold a pen in the hand without friction because it would slip out. Also the graphite point of the pencil would not make a mark on the paper without friction.
Drawbacks of friction
1. Drag. An aircraft taking off experiences significant friction between it and the air resulting in drag, so much fuel has to be used to create energy to overcome the wind resistance.
2. Surface hindrance. Friction makes moving something heavy from one part of a room to another very difficult. Sliding a large box across the flour takes a lot of energy due to friction between the box and the floor.
