Q:What is the inorganic salt in the egg
Eggs are rich in nutrients. It contains protein, fat, vitamins and inorganic salts, enzymes and so on. These nutrients on the body's growth and development, health and longevity have a great effect.
Q:Each of the fallowing is an example of an inorganic compound except one? A)water. B) bases). E)enzymes. D)salt?
anything which contain carbon is organic. so enzyme is the odd one out.
Q:What is the use of inorganic salts and organic salts?
The organics are compounds containing carbon, and the inorganic salts are salts containing no carbon. For example, we usually eat sugar is organic matter, salt is inorganic salt.
Q:I measured in the gym today in the inorganic salt protein moisture is lower than the normal value of what is the reason
The gym can also be measured
Q:What is the composition of inorganic salts?
Inorganic salts are mineral nutrients that are present in the body and in food
Q:how come inorganic salts increase surface tension of water?
Put in in a narrow tube. The narrower it is, the more surface tension it has at the meniscus.
Q:What are the effects of water, inorganic salts, carbohydrates, proteins, fats and vitamins?
The main physiological functions of minerals: 1. constitute the body of the material. (Such as calcium, phosphorus, magnesium is a bone, an important component of the teeth.) 2. Regulate the physiological function. (Minerals are often enzymes activators.) 3. Participate in the regulation of body fluid balance and maintain the body's acid-base balance.
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:What kinds of inorganic salts are required for plant growth
Only 70 kinds of chemical elements can be detected in plants, but only 16 kinds of essential nutrient elements are needed for the growth and development of internationally recognized higher plants. They are carbon (C), hydrogen (H), oxygen (O), nitrogen (Fe), magnesium (Mg), sulfur (S), iron (Fe), boron (B), manganese (Mn), copper (Cu), zinc (Zn), molybdenum (Mo) and chlorine (C1), which can be divided into large nutrient elements, medium nutrient elements and micronutrient elements according to their requirements, such as carbon, hydrogen, oxygen and nitrogen Phosphorus, potassium, copper, zinc, molybdenum and chlorine.Now there are scholars that nickel (Ni) is the first 17 kinds of essential nutrients.
Q:How to get an inorganic salt
Inorganic salts are salts of inorganic compounds, formerly known as minerals. Plant growth needs N, P, K three elements and Ca, Zn, B, Mg, S, Fe and other trace elements. Depending on the type and amount of inorganic salts required for plant life, the water and various proportions of inorganic salts are scientifically formulated into plant nutrient solutions. The method of cultivating plants with plant nutrient solution is called soilless cultivation. The inorganic salts used to prepare the nutrient solution are generally not available for extraction, such as potassium nitrate, calcium nitrate, magnesium sulfate, potassium dihydrogen phosphate, copper sulfate, zinc sulfate and the like, and the reagent may be a chemical fertilizer. The purity of the reagent is high and the impurities of the fertilizer are more. If you can not get it, you can use soil leaching solution (fertile soil plus fresh water, the liquid obtained after filtration), which generally contains a variety of inorganic salts.
