No, liquid oxygen is not a compound. It is a element with the chemical symbol O₂, meaning it is made up of molecules of two oxygen atoms bonded together.
Regardless the phase, oxygen, O2 is always formed of molecules of one element. Therefore it is not a compound.
Oxygen is both a compound and an element. In nature, Oxygen forms bonds with itself to form a compound consisting of two elemental oxygen atoms to form one compounded oxygen molecule. This is O2.
Hydrogen peroxide is a chemical compound that is classified as a peroxide due to its oxygen-oxygen single bond. It is a colorless liquid with strong oxidizing properties and is commonly used as a disinfectant and bleaching agent.
Water vapor is a compound. It is composed of two elements, hydrogen and oxygen, chemically bonded together in a fixed ratio of 2:1.
Compound water is a combination of hydrogen and oxygen atoms bonded together in a specific ratio (H2O), while hydrogen and oxygen on their own are individual elements. When combined to form water, the properties of hydrogen and oxygen change, resulting in a distinct substance with unique characteristics such as the ability to sustain life.
A mixture of hydrogen and oxygen would be a highly flammable gaseous mixture. If ignited, the mixture would burn, explode, and form water vapor. Water is not a mixture of hydrogen and oxygen but a compound.
