Jul 17, 2020 · There are a few parameters that you can use to judge whether a soil is organic or inorganic. Organic soils have fairly lower bulk densities than inorganic soils (0.2 to 0.3 as compared to 1.2 to 1.5). Organic soils will feel significantly lighter. Organic soils can retain way more water than inorganic soils (in proportions if their own densities).

Molecules associated with living organisms are organic. These include nucleic acids, fats, sugars, proteins, enzymes, and hydrocarbon fuels. All organic molecules contain carbon, nearly all contain hydrogen, and many also contain oxygen. 1. DNA 2. Table sugar or sucrose, C12H22O11 3. Benzene, C6H6 4. Methane, CH4 5. Ethanol or grain alcohol, C2H6O
Inorganicsinclude salts, metals, substances made from single elements, and any other compounds that don't contain carbon bonded to hydrogen. Some inorganic molecules do, in fact, contain carbon. 1. Table salt or sodium chloride, NaCl 2. Carbon dioxide, CO2 3. Diamond (pure carbon) 4. Silver 5. Sulfur
Few organic compounds don't contain carbon-hydrogen bonds. Examples of these exceptions include 1. Carbon tetrachloride (CCl4) 2. Urea [CO(NH2)2]
While most organic compounds encountered in chemistry are produced by living organisms, it's possible for the molecules to form through other processes. For example, when scientists talk about organic molecules discovered on Pluto, this doesn't mean there are aliens in the world. Solar radiation can provide energy to produce organic compounds from ...

Nov 25, 2021 · Soil chemistry is a branch of soil science that deals with the chemical composition, chemical reactions and chemical properties in soils. Abiotic phases of the soil include solids (organic matter and inorganic minerals), liquids (soil water), and gases (soil air), while the biotic phase consists of living organisms.
Rank the five colloids discussed in terms of Cation Exchange Capacity (1= highest, 5=lowest). Explain why this is. 1: Organic/humus. 2: Smectite. 3: Fine grained mica. 4: Kaolinite. 5: Oxides. This is directly related to how much internal surface area each type has. Organic colloids have large internal surface areas.

Jun 26, 2021 · Soil chemistry is primarily concerned with the chemical reactions associated with the many phases incorporated within the soil mixture. Soil chemistry is an ever-expanding field that traditionally focused on chemical reactions that affected plant growth and nutrition, and has since expanded to include water and soil contaminants and their effects on plants, animals, and humans.
