Simple Examples:
* The chemical formula for water is H₂O.
* Sodium chloride, commonly known as table salt, has the chemical formula NaCl.
* CO₂, or carbon dioxide, is a greenhouse gas that contributes to climate change.
More Complex Examples:
* The reaction between sodium hydroxide (NaOH) and hydrochloric acid (HCl) produces salt (NaCl) and water (H₂O).
* The chemical formula for glucose is C₆H₁₂O₆, and it's a primary source of energy for living organisms.
* Understanding the chemical formulas of different compounds is crucial for scientists in fields like medicine, engineering, and agriculture.
Key Points:
* Capitalization: The first letter of an element symbol is always capitalized, while the second letter (if there is one) is lowercase.
* Subscripts: Subscripts indicate the number of atoms of each element in a molecule.
* Parentheses: Parentheses are used to group atoms together, especially when they are a repeating unit within a larger molecule.
