A general term for a chemical that makes a specimen visible is a stain. There are many types of stains available, depending upon the structure you want to visualize and the type of microscope you want to use, e.g. fluorescent stains like DAPI for fluorescence microscopy, or hematoxylin and eosin (H and E) staining for brightfield microscopy.Immersion oil
Methylene blue is an example.
Methylene blue
In a chemical equation, a substance in water solution is denoted by the subscript (aq). For example, aqueous potassium chloride would be represented in an equation as KCl(aq)
An example is methylene blue.
its a structure dude, for example there is no example and you have to find that example out to know the example. did you get it yo
The boiling point of a substance is an example of a physical property of that substance.
Symbols are used when showing the molecular structure of a substance, for example the molecular structure of water is H2O meaning that it has 2 hydrogen atoms (H) and 1 oxygen atoms (O)
Rubber is a resilient substance.
Oh yes, water is a substance.
Chemicals are represented by the chemical formula or by digital codes (for example the Chemical Abstracts number).
The screening constant is the quantity represented by omega. It is determined by the electron density and the spatial distribution of the electrons around a nucleus. This value differs for different protons. For example, protons (H) in a methyl group has a larger screening constant as compared with protons in a methylene group. The screening constant for an isolated hydrogen nucleus is zero.
