Q:are acids, bases, salts and oxides belong to inorganic compound?
I think organic compunds are anything with Carbon(C), although I really don't know.
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:Trace Minerals Advice?: Just read somewhere that dehydrated sea salt trace minerals are inorganic, and?
Inorganic does not mean indigestible, but plant derived trace minerals are the best form to take because they have been broken down by soil micro-organisms and predigested by plants, making them much more bioavailable than minerals which have not. I use Liquid Life trace minerals. EDIT: The best source would definitely be diet except that our soils have had a whopping 85% mineral depletion over the past hundred years thanks to over-farming. Your great grandma's bowl of spinach had eight times the nutrition that the bowl you eat today has.
Q:Advertisements related to inorganic salts -.-,
Three crystal good mother know every night to give her blue bottle, and help absorb the blue screen of the drink, Harbin Pharmaceutical six factory production.
Q:The lack of symptoms and food sources of several inorganic salts
Food sources of inorganic salts containing calcium Source: dairy products, beans, cereals, kelp and so on. Source: seafood, etc. Food of iron-containing inorganic salts Source: Fruits Containing iodine-containing inorganic salts Source (trace): seaweed, jellyfish, corn, mussels, etc. Zinc-containing inorganic salt food sources (trace): animal liver (viscera), fruit, peanuts, etc.
Q:How much of the body's inorganic salts account for the weight of the body?
The inorganic salts in the human body account for about 5%
Q:The human body does not intake of minerals can be? Lack of minerals on the human body what kind of harm?
Body weight: 96% is organic matter and moisture, 4% for the inorganic elements of the body about 50 kinds of minerals, in these inorganic elements, has been found in about 20 elements constitute the body tissue, to maintain physiological function, Biochemical metabolism necessary, in addition to C, H, O, N mainly in the form of organic compounds, the rest are known as inorganic salts or minerals can be divided into constant elements and trace elements two categories.
Q:Are plants absorbing water and inorganic salts only through root tip or wrong?
Plants through the leaves can also absorb water and inorganic salts, but the root tip is the main part of the plant to absorb water and inorganic salts.
Q:Magnesium can constitute chlorophyll, which reflects the nature of inorganic salts
to maintain the body's acid-base balance
Q:Effect of Inorganic Salts on Viscosity
possible. The inorganic salt is dissolved in water to form positive and negative ions, and the ions of the micelles are extruded to make the solubility smaller and form an increase in the viscosity. With the increase in the amount of inorganic salt, it does not have the ability to dissolve in water, there is no micelles and the molecular state exists in the water, the liquid becomes thin ...
