Chemical Formulas List
Chemical Formulas List
Chemical formulas are shorthand representations of molecules and compounds, showing the elements and their ratios within a substance. Below is a list of common chemical formulas, each with an example to demonstrate its application.
1. Water (H2O)
Formula: H2O
Example: Water is essential for all known forms of life. It consists of two hydrogen atoms bonded to one oxygen atom.
2. Carbon Dioxide (CO2)
Formula: CO2
Example: Carbon dioxide is produced by plants and animals during respiration and is used by plants in photosynthesis.
3. Sodium Chloride (NaCl)
Formula: NaCl
Example: Common table salt, used in cooking and food preservation, consists of sodium and chloride ions in a 1:1 ratio.
4. Glucose (C6H12O6)
Formula: C6H12O6
Example: Glucose is a simple sugar used by living organisms as an energy source.
5. Ammonia (NH3)
Formula: NH3
Example: Ammonia is commonly used in cleaning products and as a fertilizer in agriculture.
6. Methane (CH4)
Formula: CH4
Example: Methane is a greenhouse gas and a major component of natural gas, used as fuel.
7. Sulfuric Acid (H2SO4)
Formula: H2SO4
Example: Sulfuric acid is widely used in industry, especially in battery acid and fertilizer production.
8. Calcium Carbonate (CaCO3)
Formula: CaCO3
Example: Found in rocks like limestone and marble, calcium carbonate is used in construction and as a dietary supplement.
9. Ethanol (C2H5OH)
Formula: C2H5OH
Example: Ethanol, also known as alcohol, is commonly used in beverages and as a fuel additive.
10. Hydrochloric Acid (HCl)
Formula: HCl
Example: Hydrochloric acid is used in various industrial applications, including metal processing and pH control.
Conclusion
Understanding chemical formulas and their applications is essential in fields like chemistry, biology, and industry. These formulas represent substances we encounter daily and are foundational to chemical reactions and processes.
