One can thus see how a substance (monomer) with as small a molecular weight as 54 grows to become a giant molecular (polymer) of (54 × 4000 ≈)200000 molecular weight. It is essentially the 'giantness' of the size of the polymer molecule that makes its behavior different from that of...
Water makes up what percentage of the weight of living plants and animals?Question:Water makes up what percentage of the weight of living plants and animals?Water:Water is actually a chemical compound. One molecule of water is made up of two atoms of hydrogen and one atom of...
b) A molecule of water is consumed. Its atoms are added to a bond, putting an OH group on one end and a hydrogen atom on the other. c) Explain how stable monosaccharides are assembled into energy storage and structural polymers. Give examples. What is the name of the molecule on ...
There are a few derivatives of renewable hydrogen:Renewable ammonia is produced from both green hydrogen and nitrogen that’s extracted from the air. Ammonia can be used as a precursor for fertilizers, as clean fuel, or as a hydrogen carrier molecule. Renewable e- or green methanol is ...
In liquid perfume, the liquid is a mixture of alcohol, water and molecules that evaporates at room temperature. "A smell is basically a molecule that's light enough to float in the air, although not every molecule that's light enough to float in the air has a smell -- carbon monoxi...
practical capabilities by considering how molecules interact, combine and coordinate to produce functionalities at higher levels of the scale hierarchy. ‘Molecule’ is used not as a tightly-defined way of joining up atoms, but as a shorthand term for a certain scale and mode of chemical thinking...
A water molecule(分子)is composed of 2 hydrogen atoms and 1 oxygen atom.It can be changed only by special working skillfully of the atoms.The material making up the cup can have nanometer particles.But it cannot change the chemical and physicalpropertiesof the water contained in it.The water...
Atoms are the building blocks of matter. A combination of atoms forms amolecule. Large groups of atoms and molecules form the bulk matter of day-to-day life in the physical world. There are more than 100 different kinds of atoms listed in the periodic table, with each kind constituting a...
Here, six molecules of carbon dioxide (CO2) combine with 12 molecules of water (H2O) using light energy. The end result is the formation of a single carbohydrate molecule (C6H12O6, or glucose) along with six molecules each of oxygen and water. ...
9) The researchers say this is the first time that artificial intelligence has been used to find a powerful new antibiotic molecule. Why does this matter? The answer is antibiotic resistance. This happens when bacteria developed the ability to survive the medications designed to kill them. 10) ...
