Q:Acids, salts, and metals are examples of?
Acids, D. water soluble inorganic chemicals salts, D. water soluble inorganic chemicals metals E. sediment
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:List the major electrolytes released by inorganic salts when placed in water and explain how these electrolyte?
Which "inorganic salts" are you talking about? There are hundreds!
Q:What is inorganic salt
Inorganic salts are mineral nutrients that are present in the body and in food, and are composed of organic matter and inorganic matter. The body has been found to have more than 20 kinds of essential inorganic salts, about 4 to 5% of body weight. (> 5g) is calcium, phosphorus, potassium, sodium, chlorine, magnesium, sulfur seven kinds of daily dietary requirements are more than 100mg, known as constant elements. In addition, the contents of iron, iodine, copper, zinc, manganese, cobalt, molybdenum, and selenium were studied by means of atomic absorption spectroscopy, neutron activation and plasma emission spectroscopy. , Chromium, nickel, silicon, fluorine, vanadium and other elements is also essential to the human body, daily dietary requirements for the amount of μg ~ mg called trace elements.
Q:Potassium chloride is called a mineral salt. What sort of chemical is a mineral..?
A mineral is mostly an inorganic salt that can form naturally in the earth. Potassium citrate on the other hand is an organic salt which is formed by addind an potassium base to citrate acid (citrate acid is an acid that is found in fruits and is termed organic as it is mostly has carbon atoms in it)
Q:Inorganic salt is not salty
NaOH (sodium hydroxide) dilute: basically with the thick Na2CO3 (I tasted, salty), more spicy (strong resistance to protein corrosive). Concentrated: very spicy in the mouth ( May have been a reaction) and then burned the tongue, was **, meat rot, 1 month can not speak, mouth pain and tongue numbness has a sense of spicy six months after discharge, speech becomes not allowed, the taste almost disappeared, The mouth left a scar (this thing on the protein reaction is not a joke ... ...).
Q:The lack of three major inorganic salts can cause symptoms in the plant
Nitrogen: to promote cell division and growth, so that leaves grow lush. Lack of performance: plant thin and thin, leaves yellow, severe leaves were light brown.
Q:Where are the parts of the bryophyte absorb water and inorganic salts?
Moss moss moss, moss Gang, moss root through the fake root absorption, that is, the use of cell penetration technology, moss Gang has evolved out of the root, so you can directly through the relatively low roots to absorb Oh
Q:Liver cancer diet should pay attention to what issues?
Inorganic salts: minerals. Nutritionists divide inorganic salts into two categories: constant elements such as calcium, sodium, potassium, phosphorus, iron and the like; trace elements such as selenium, zinc, iodine, copper, manganese and germanium. Scientists have found that selenium, magnesium, copper, magnesium, iron and other minerals have anti-cancer effect. Liver cancer patients should eat more foods containing anti-cancer trace elements such as garlic, mushrooms, asparagus, corn, seaweed, seaweed, seaweed, clams, sea fish, egg yolk, brown rice, beans, whole wheat flour, nuts, pumpkin, , Kohlrabi and animal liver, kidney and ginseng, medlar, yam, Ganoderma lucidum and so on.
Q:what is leading inorganic salt of nervous system?
The sodium-potassium pump is most important in controlling the working of neurotransmitters. Calcium ion is also generated in voltage gated Ca++ channel, and Magnesium is necessary for metabolic functions. But Sodium is one of the most important inorganic component in our body. Of course Potassium is also as important. But, if you have ever seen the back of all food products there is a special part showing amount of Sodium in it...even Snacks.. :)
