What is the chemical formula for water?

• A. CO2
• B. O2
• C. H2O
• D. CH4

Answer: (C)

The chemical formula for water is represented as H2O, which indicates that each molecule of water consists of two hydrogen atoms bonded to one oxygen atom. This composition is fundamental in chemistry and illustrates a key principle of molecular structures, where the subscripts denote the number of each type of atom present. Water plays a vital role in various chemical processes and is known as a universal solvent due to its ability to dissolve many substances. The bonding in H2O is polar covalent, which leads to the unique properties of water, such as its high surface tension, specific heat capacity, and solvent capabilities. These properties are crucial for supporting life and various biological processes. In contrast, the other options provided refer to different substances: carbon dioxide (CO2) consists of one carbon and two oxygen atoms; oxygen (O2) is a diatomic molecule of oxygen; and methane (CH4) comprises one carbon atom bonded to four hydrogen atoms. Understanding the correct formula for water is essential for grasping broader chemical concepts and their applications in science.
