Q:Each of the fallowing is an example of an inorganic compound except one? A)water. B) bases). E)enzymes. D)salt?
The correct answer is enzymes. Enzymes are composed of carbon, nitrogen, oxygen and traces of other elements such as sulfur, but are produced in nature only by living things.
Q:Does the inorganic salt fight the mass spectrum?
Can it be specific? What mass spectrometer, which inorganic salts. Do EI need samples can be vaporized, inorganic salts obviously not appropriate
Q:People do not eat salt tears with no inorganic salt
I suddenly think of a science program that found a place a strange person, never drink water, then a variety of surprises. Finally, the scientist came out to explain that he can get the daily water needed from the food.
Q:Sodium bicarbonate is not an inorganic salt
Yes, organic refers to salts with carbon skeleton chains other than carbon and carbon oxides and carbonates, so sodium bicarbonate is an inorganic salt
Q:Determination of the existence of inorganic salts in the soil, in the filter, should pay attention to the matter
Filter should pay attention to is a "paste, two low, three by".
Q:What is the use of inorganic salts in plants?
Plants need inorganic salts, just as people need trace elements, the growth of auxiliary organisms can be through the leaves of the surface of the pores, with the water discharged together
Q:Is iodized salt inorganic or organic?
"Iodized salt" is sodium chloride which contains minute amounts of iodine-containing salts. The most commonly added iodine salts are: potassium iodate, potassium iodide, sodium iodate, and sodium iodide. All of these compounds are inorganic. By the way, while methyl iodide is organic, it is not a salt.
Q:salt is organic or inorganic?
any salt is ionic which means ionic bonds, and carbon mostly forms covalent bonds, so it is very very unlikely that a salt contains carbon making it organic so most if not all salts are inorganic
Q:Eat what food can add inorganic salt
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. According to their content in the body how much can be divided into constant elements and trace elements two categories. The body is actually composed of various elements (macro and trace). Many of these mineral elements are essential components of the enzyme, which can regulate a variety of physiological functions (such as maintaining osmotic pressure, oxygen transport, muscle contraction, nervous system integrity), but also tissue and bone growth and maintenance necessary. Some (such as calcium, phosphorus, sodium, magnesium, sulfur, chloride) content is large, while others are only trace. Human essential trace elements are cobalt (such as vitamin B12), copper, fluorine, iodine, iron, zinc, chromium, selenium, manganese, molybdenum In terms of its impact on experimental animals, nickel, tin and arsenic should also be considered necessary. Most minerals (except zinc) are widely distributed in a variety of foods and can be fully supplemented by balanced and diversified diets. However, there is a need for additional supplements to patients who have been relying on intravenous nutrition for long periods of time, infants and older persons, or because of the lack of regionalities caused by soil and water quality.
Q:What is the risk of low inorganic salt?
Iodine content in the human body is much lower than 1/10000  is a trace element. Function  iodine in the human body to participate in the formation of thyroid. In the protein, fat, sugar metabolism  promote bio-oxidation and coordination of oxidation of phosphoric acid process, adjust the energy conversion. Promote the metabolism of sugar and fat, regulate the water and salt metabolism in the organization, promote the absorption and utilization of vitamins, activate many important enzymes, promote growth and development. Lack of disease  adult iodine deficiency can cause goiter ⑴ fetal and neonatal iodine deficiency can cause minor illnesses. Typical cases  endemic goiter and local minor illnesses. Excessive symptoms  iodine goiter, iodine thyrotoxicosis. Supply  Adult 150ug  Pregnant woman 175ug 206 Emulsifier 200ug. Food source 海 seafood seaweed, seaweed, fresh fish, clam dry, clam dry, scallops, mussels hai sea cucumber, jellyfish, lobster, etc.
