Q:What is the difference between inorganic and inorganic salts?
Humus: refers to the biological decomposition of the remaining rich in a large number of beneficial effects on the soil containing the material, but also the whole ecosystem has a direct positive effect.
Q:Are fruits and vegetables inactive?
Inorganic salts are inorganic compounds in the salt, formerly known as minerals, the body has found more than 20 species, including constant elements of iron, zinc, selenium, molybdenum, chromium, cobalt, iodine 8. Apple, pipa, durian, citrus, Watermelon, kumquat, peanuts, I know so much. Oh, there are: lotus lotus which contain inorganic salts
Q:Sodiumcorbonate is inorganic salt , why it is not organic substance even it contains carbon?
Organic molecules have carbon to carbon bonds. EDIT: I wonder why I got a thumb down for stating the definition of an organic molecule? Yahoo answers is a weird place. If there's only one carbon atom in a molecule its not an organic molecule, because there can be no C-C bonds...
Q:Several inorganic salts are lacking in symptoms and food sources
Ingredients of zinc-containing inorganic salts (trace): animal liver (viscera), fruit, peanuts, etc.
Q:A colorless solution contains which inorganic salt?
Only Zn compounds form colorless or white salts. The second question would be the last answer, which is false. It forms an alkaline solution when added to water.
Q:What to eat can promote the absorption of inorganic salts
The inorganic salt is required to enter the carrier in the cell membrane that requires the cell membrane
Q:Calcium is not an inorganic salt
No, inorganic salts are compounds, calcium is simple. But the body of inorganic salts in the calcium content accounted for a larger proportion.
Q:Anyone familiar with GC? Is it safe to put an alcohol + inorganic salt water mix into a GC?
Do not let salts enter the GC. You will have to perform an extraction step and run that. Salts can precipitate in the column or degrade into reactive species that can corrode the GC. Water is OK since it will not destroy the column (I've run aqueous solutions before), but salts are not.
Q:What is the difference between organic salt and inorganic salt?
Organic and inorganic chemistry are subdisciplines within chemistry. In organic chemistry, scientific study is concentrated towards carbon compounds and other carbon-based compounds such as hydrocarbons and their derivatives. Read more: www.differencebetween.net/science...
Q:RO reverse osmosis water machine can remove impurities in the water, that the body will not be due to lack of minerals and malnutrition?
Dr. Henry A. Schroeder, the world's mineral authority, says that the minerals required by the human body are present in the water, meaning nothing more than those that exist in food.
