- Q:The inorganic portion of bone tissue is made of what complex mineral salt ?
- hydroxyapatite - Ca10(PO4)6.(OH)2 - which covers the calcium and phosphorous that are needed for bone development And just so you know, plants don't have "bones" - your question was posted in Botany.
- Q:What are organic and inorganic salts?
- An organic salt is a salt containing an organic ion ( carbon atoms ) The reaction product of an organic acid and an inorganic base, for example, sodium acetate (CH3COONa) from the reaction of acetic acid (CH3COOH) and sodium hydroxide (NaOH). The Organic ion, here, is CH3COO- Inorganic compounds come principally from mineral sources of non-biological origin. The modern definition of inorganic compounds often includes all metal-containing compounds, even those found in living systems. So, Inorganic salts are salts of such elements (salts that don't contain carbon atoms) For eg: NaCl, KCl, BaCl2, Al2SO4, etc
- Q:Is bromine an inorganic salt?
- It has many uses such as: · fumigants · flameproofing agents · water purification compounds · dyes · medicines · inorganic bromine (AgBr) is used in photography film · pesticides · water purification · used to make plastics flame retardant · In gold extraction...!!
- Q:Magnesium can constitute chlorophyll, which reflects the nature of inorganic salts
- , to maintain the osmotic pressure of cells, especially for the absorption of nutrients in plants have an important role.
- Q:What foods contain inorganic salts?
- 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. Kelp, jellyfish, seaweed, moss; bones, soy products, lean meat, animal liver, brown rice and so on.
- Q:Of the dissolved salts found in seawater, _____ % are minor inorganic salts, or trace.
- it's definitly one of these: 99.28 .72 72 50 i think it's 99.28. lemme no if you get it right!!
- 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:A solution is known to contain an inorganic salt of one of the following elements. The solution is colorless. The solution contains a salt ofa. Cub. Mnc. Fed. Nie. Zn
- Mn or Zn. Both MnSO4 and ZnSO4 solutions are water-white. KMnO4 is purple. But you did not stipulate.
- 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:What are the effects of inorganic salts on plant growth?
- In addition to these three types of inorganic salts, plants also require many types of inorganic salts. Among them, the demand for some inorganic salts is very small, but they are in the life of the plant also plays a very important role. For example, the lack of inorganic salts containing Fe, fruit trees will be yellow leaf disease; lack of inorganic salts containing B, rape will be "flowers and not real" (only flowering fruit).
