Answer:
n = 3 to n = 5
Explanation:
According to the Bohr's model of the atom, electrons in an atom absorb energy to move from a lower to higher energy level.
We must note that as we progress away from the nucleus, the energy levels of electrons become closer together. The energy difference between successive levels decreases and the wavelength of light associated with such transitions become longer.
Hence,the absorption of light of the longest wavelength corresponds to n = 3 to n = 5

Answer:
It might be responding variable.
Answer: combustion reaction.
Explanation:
Gasoline is a mixture of hydrocarbons (with some other dded substances in minor proportion).
Assuming a hypothetical composition of the gasoline as C₅H₁₂ (only for explanation purposes), the chemical reaction that occurs when gasoline is burned is represented by:
- 2C₅H₁₂ + 16O₂ → 10CO₂ + 12H₂O + energy.
Combustion is a special type of chemical reaction, in which oxygen combines with other substance (element or compound) releasing a large amount of energy in the form of heat and light. It is a very common reaction of the hydrocarbons and the products are carbon dioxide and water in the form of vapor.
The combustion of carbon (C) is a very important and common reaction that has been using to produce energy: C(s) + O₂(g) → CO₂ (g)
The energy needed to remove an electron from an atom is called ionization energy.
