Various carbon-containing substances that have been by some considered to be “inorganic” are examined in an attempt to ascertain whether carbon in these compounds display different chemical behavior than what is expected of carbon in an “organic” substance. Types of substances considered are ...
Examples of insoluble substances are sand, plastic, wood, metal, glass and cloth.These substances never dissolve in water or any other solvent at room temperature and pressure. Sugars and inorganic salts are also examples of insoluble substances. Insoluble substances cannot be extracted from a soluti...

The common feature of all these phenomena is that the microorganisms are embedded in a matrix of extracellular polymeric substances (EPS). The production of EPS is a general property of microorganisms in natural environments and has been shown to occur both in prokaryotic (Bact...
Ice is a naturally occurring, inorganic solid with a definite chemical composition and an ordered internal structure. Learn more. The Word "Mineral" The word "mineral" is used in many different ways. Here are some examples: Geologist's Definition A formal definition of a mineral, as used by...
What are some physical properties of minerals? Minerals: Minerals are inorganic compounds or species that have specific structures and properties that are well defined. These properties can be physical or chemical and are characteristic of each mineral, making it possible to classify and identify them...

Humic substances, strongly transformed, high-molecular substances without recognisable tissue structures. Scattering substances that are not or only slightly transformed and in which the tissue structures are largely still morphologically visible. These include above-ground dead plant remains as well as dead...
What are Minerals? - A mineral is a natural inorganic solid with a specific internal structure and a chemical composition that varies only within specific limits. Minerals are the solid constituent of earth. Visit BYJUS to learn more about it.
