In a chemical reaction, atoms are rearranged and bonds between them are broken and formed to create new substances. Molecules can be broken down into smaller molecules or combined to form larger molecules through chemical reactions. Overall, chemical reactions alter the arrangement of atoms and molecules to create different substances with unique properties.
Water is the substance in body fluids that determines most of their chemical and physical reactions. It serves as a solvent for various molecules, participates in metabolic reactions, helps regulate body temperature, and maintains cell structure and function.
These are decomposition reactions.

The outermost electron of an atom that participates in chemical bonding is known as a valence electron. Valence electrons are located in the outermost shell of an atom and determine its chemical properties and reactivity. These electrons can be shared, lost, or gained during chemical reactions, forming bonds with other atoms to create molecules. The number of valence electrons influences the type of bonds an atom can form, such as ionic or covalent bonds.
The diagram of molecules shows how atoms are arranged in a molecule. In chemical reactions, molecules interact and rearrange their atoms to form new substances. The diagram helps us understand how molecules change during a chemical reaction.

Oxygen can take part in a variety of reactions, such as combustion (burning), oxidation reactions, and reactions in biological processes like respiration. It is a highly reactive element that readily participates in chemical reactions.
