Yeast species either require oxygen for aerobic cellular respiration (obligate aerobes) or are anaerobic, but also have aerobic methods of energy production (facultative anaerobes). Unlike bacteria, there are no known yeast species that grow only anaerobically (obligate anaerobes). Yeasts grow best in a neutral or slightly acidic pH environment. (Wikipedia:Yeast)
Oxygen is a molecule.
O3 is a molecule / compound, not element
Liquid oxygen is a compound, specifically a molecule composed of two oxygen atoms bonded together (O2).
No, Nitrogen(IV) Oxide is a covalent compound which is a gas at room temperature.
The water molecule is a compound of hydrogen and oxygen sort of fused together.
Acetone is a molecular compound. It consists of individual molecules made up of covalently bonded atoms, specifically carbon, hydrogen, and oxygen.
no, an example of a compound would be sugar (c6h12o6)
Oxygen is a molecule because it consists of two oxygen atoms bonded together. A compound, on the other hand, is a substance made up of different types of atoms bonded together. Since oxygen is made up of only one type of atom (oxygen), it is considered a molecule and not a compound.
Water, H2O, is a molecule of hydrogen and oxygen. It is considered a compound. That said, yes, oxygen and hydrogen combine to make a compound that is represented by the molecule H2O.
Carbon Dioxide (two oxygen molecules and one carbon molecule)
No, oxygen is an element, not a compound. It is a pure substance made up of just one type of atom, specifically oxygen atoms. Compounds are made up of two or more different elements chemically bonded together.
Copper oxide is a chemical compound composed of copper and oxygen atoms, not a molecule. It is an inorganic compound that forms when copper reacts with oxygen.
