Answer:
Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions.
Explanation:
The name and chemical symbol of the elements are
- Carbon = C
- Lead = Pb
- Antimony = Sb
- Sodium = Na
- Aluminum = Al
<h3>What are chemical symbols?</h3>
Chemical symbols are which are used to represent the elements in the periodic table.
The chemical symbol assigned to elements are usually an abbreviation of the name of the element or the Latin form of the name.
The name and symbol of the given elements are as follows:
- Carbon = C
- Lead = Pb
- Antimony = Sb
- Sodium = Na
- Aluminum = Al
The chemical symbols are used frequently in writing the formula of compound formed from the elements. For example, the compound sodium aluminate which contains sodium, aluminum and oxygen is written in a simplified form as: NaAlO₂.

Answer:

Explanation:
R = Rydberg constant = 
= Principal quantum number of an energy level = 2
= Principal quantum number of an energy level for the atomic electron transition = 4
Wavelength is given by the Rydberg formula

The wavelength of the light emitted is
