There are many compounds that contain oxygen, ranging from very simple to very complex. Water is one simple compound that contains oxygen, as well as carbon dioxide, magnesium oxide, and formaldehyde. A more complex example is sucrose, also called table sugar.
Water, quartz, rust, and sugar are all common, important compounds containing oxygen.
No, oxygen cannot be liberated from all oxygen-containing compounds. Some compounds contain oxygen in a very stable form, such as in water (H2O), where the oxygen is tightly bound to hydrogen. Releasing oxygen from these compounds would require significant energy input.
carbon dioxide (CO2), water (H2O), and carbonmonoxide(CO) are only a few compounds containing oxygen.
Our metabolisms take advantage of a reaction between oxygen gas and compounds such as glucose to release energy. Oxygen compounds do not contain the same energy and do not react in quite the same way with other substances, so we cannot use them. Most substances that are as reactive as oxygen are toxic, but we have adapted specifically to be able to use oxygen.
Some compounds that contain hydrogen and oxygen include water (H2O), hydrogen peroxide (H2O2), and methanol (CH3OH).
Water, quartz, rust, and sugar are all common, important compounds containing oxygen.
magnesium and oxygen are elements. They are not compounds
Water and vinegar are both compounds, oxygen is an element.
All oxides, peroxides, superoxides, ozonides and compounds with oxy-anions have oxygen atoms in them.
All organic compounds contain carbon and hydrogen as a minimum. Other elements are found in some organic compounds such as oxygen, nitrogen or sulphur.
The oxidation number for oxygen in most compounds is -2.
H20, HO2, CO2, Al2O3, etc.
