molecules or 'macro-molecules' are made up of much smaller molecules. The small molecules, which combine to form a big molecule, can be of one or more chemical compounds. To illustrate, imagine that a set of rings has the same size and is made of the same material. When these rings ...
If the two atoms are the same element, it is called ahomonuclear diatomic molecule, such as oxygen (O2) and nitrogen (N2).Polyatomic moleculeshave more than two atoms, such as water (H2O) and carbon dioxide (CO2). Larger molecules are calledpolymersand may be made of thousands of atoms...
This liberated carbon dioxide formed the thick atmosphere of present-day Venus. Over time, the rising temperatures would have leveled off, solar ultraviolet radiation having broken down atmospheric water vapor molecules into hydrogen and oxygen. With all the water vapor gone, the greenhouse effect ...
Intermediate WaterWhen the biomaterials come into contact with the biological fluids, water molecules immediately adsorb onto the surface of the materials. To understand the origin of the crucial roles of water molecules in biological interfaces, it is necessary to relate particular stats of hydration ...
acid reacts with the hydroxyl group on each carbon atom of a glycerin molecule. This results in each fatty acid molecule being bound to a carbon atom in the glycerin molecule. This process also liberates a molecule of water for each fatty acid molecule for a total of three water molecules...
