- Q:are there any other foods than water and salt that have an abiotic origin (lifeless, inorganic)?
- Various minerals we need, like iron, zinc, magnesium, etc. That's it. These also are not technically foods, as the first poster said.
- Q:What does salt form when it dissolves?
- Most inorganic salts are ionic in nature and therefore it will dissociate in ions. For example Copper sulphate will dissociate in Cu+2 and SO4 -2 ions. If the dissociation energy of the salt is too high, it will remain partially or completely as salt in the solution. large number of organic salts do not dissociate completely and the solution will contain Ions and salt - both.
- Q:Inorganic salt is not salty
- HCl (hydrochloric acid) dilute: more acid, feeling slippery mouth, the typical vomit feeling, slightly spicy. Concentration: extreme acid, spit after the bitter taste, and then the whole mouth cold, 10 minutes later improved.
- Q:Why can quaternary ammonium salts catalyze the heterogeneous reaction between water-soluble inorganic salts and organic compounds
- Quaternary ammonium salts have the characteristics of surfactants, with the water phase of the nucleophile in the composition of the ion pair, into the organic phase, thereby promoting the heterogeneous reaction faster 6224
- Q:what percent of dissolved salts found in seawater are minor inorganic salts, or trace?
- Seawater varies in composition a little but generally is about 3.5% salts. Of this about 3.1% is sodium chloride. So the remaining 0.4% is the other salts (Magnesium, Calcium and Potassium mostly, followed by just about every natural element in the periodic table in trace amounts)
- Q:Does the plant absorb some of the inorganic salt?
- Of course, plant water absorption and absorption of inorganic salts are a certain association, inorganic salts to be dissolved in water to be absorbed, and inorganic salt ions in the transport of plants can not be separated from water.
- Q:How can experiments prove that there are inorganic salts in the leaves of plants
- The experimental leaves used to dry, crushed into powder or sintered ash, and then the analysis of mineral elements, we can learn.
- Q:What foods contain inorganic salts?
- Most of the food contains inorganic salts, the so-called inorganic salts, also known as minerals or ash. Minerals are naturally occurring compounds or natural elements in the crust. There are about 50 kinds of minerals in the human body, although they in the human body only 4% of body weight, but it is an essential part of the organism. Kelp, jellyfish, seaweed, moss; bones, soy products, lean meat, animal liver, brown rice and so on.
- Q:What cells produce the collagen and inorganic salts of bone matrix?
- Inorganic Salts In Bone
- Q:Which crop feet can provide C N inorganic salts for fungal growth
- Plant growth requires a variety of inorganic salts, which require the most is nitrogen, phosphorus, potassium containing inorganic salts. If a lack of some inorganic salts, plants can not grow normally. Kind of crops need fertilization, farm manure contains organic matter, the microbial decomposition of the soil will produce a large number of inorganic salts for plant growth and utilization, the role of fertilizer is to provide a variety of plant growth of inorganic salts. Therefore, in agricultural production, the application of fertilizer and farm manure is intended to provide a variety of inorganic salts for crops.
