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:Magnesium can constitute chlorophyll, which reflects the nature of inorganic salts: to maintain the body's acid-base balance

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:Octopus why the lack of boron-containing inorganic salts can cause rape to flow only without fruit: Boron has a great influence on the reproductive process of plants, which can accelerate pollen differentiation and pollen tube elongation. In the absence of boron, pollen tube germination is affected, poor fertilization, which leads to the formation of seeds affected, the reduction of growth hormone produced by the reduction of growth hormone will affect the formation of fruit.

Q:in the ocean: Salts are the result of the association of cations and anions. Cations are usually metals like Calcium, Sodium, Potassium anions are ususally sulfates, phosphates, carbonates...... calcium carbonate and calcium phosphate are useful in making bone. Potassium Chloride is important in heart beat regulation Sodium Chloride is important in maintaining blood pressure. Carbonate is important in blood chemistry and the transfer of energy within a cell. all these salts are found in abundance in the ocean. If you follow evolution, those salts in the ocean have given rise to our own blood chemistry and organic health.

Q:What does salt form when it dissolves?: ions. depending on which kind of salt: NaCl -> Na+ + Cl-

Q:What are the nutritional requirements for bacterial growth?: The nutritional conditions required for bacterial growth generally include water, carbon, nitrogen, inorganic and growth factors

Q:I am told to find which bottled mineral water brands contain the most mineral salts.But im not sure if the mineral salt here is talking about the common table salt (Sodium Chloride) or the chemical salt (ionic compounds such as sulfate and chloride) or the whole list of dietary minerals (potassium, chlorine, calcium, magnesium, ect.) I normally think it is just the table salt but im afraid I might get wrong. So what is the exact definition?: it okorder /C005969/mi... "Mineral salts are inorganic (carbon-free) elements that turn to ash when burned. "

Q:Think about the physical and chemical properties of salt and sugar. What properties do these substances have in common? Describe which properties you could use to distinguish between them. What properties and units would you use to describe their physical and chemical characteristics? List as many as you can.: I believe it's Physical, most of the times such changes are physical, melting point, sublimation, evaporation, etc.
