I understand. Looks like there are some ways to figure it out, but still a novice guess in most instances until you become more familiar with substances and properties. So before we close this topic, or we can continue, What about the -ates, -ites? Or does it just depend?

Although UV rays have wavelengths that are shorter, UV rays are shorter than those of X-rays, they possess more energy. This is beneficial in breaking chemical bonds. These waves are often referred to as nonionizing radiation. In biochemistry, the UV spectrum is typically used to measure the...

Modeling chemical reactions helps engineers virtually understand the chemistry, optimal size and design of the system, and how it interacts with other physics that may come into play. This is the first of a series of blog posts on chemical reaction engineering, and here we will have a look ...
The chemical structure of glucose At any given moment, all of the work being done inside any cell is being done by enzymes. If you understand enzymes, you understand cells. A bacterium like E. coli has about 1,000 different types of enzymes floating around in the cytoplasm at any given...
