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:What is the inorganic salt in the egg
Carbohydrate (g) 3.1 Vitamin C (mg) 0 Manganese (mg) .02
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:Inorganic salt is not salty
HCl (hydrochloric acid) dilute: more acid, feeling slippery mouth, the typical vomit feeling, slightly spicy. Concentration: extreme acid, spit after the bitter taste, and then the whole mouth cold, 10 minutes later improved.
Q:What is the use of inorganic salts in plants?
Nitrogen is the constituent of chlorophyll, chlorophyll a and chlorophyll are all nitrogen compounds. Green plants for photosynthesis, so that light energy into chemical energy, the inorganic (carbon dioxide and water) into organic matter (glucose) is the role of chlorophyll. Glucose is the raw material for the synthesis of various organic substances in plants, and chlorophyll is the factory for the manufacture of "grain" for plant leaves. Nitrogen is also an integral part of vitamins and energy systems in plants. The transpiration of plants, taken away by water, is similar to human sweating
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:TRUE OR FALSE: the addition of salts to water will always increase the surface tension of water. explain.?
False. Although inorganic salts will increase surface tension of the water by increasing the attractive forces between water molecules on the surface, organic salts will typically (always?) decrease the surface tension.
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:What are these salts used for please?
HI I'M PNT. LITHIUM SULFATE is a white inorganic salt with the formula Li2SO4. It is used to treat bipolar disorder. It is soluble in water, though it does not follow the usual trend of solubility versus temperature — its solubility in water decreases with increasing temperature . This property is shared with few inorganic compounds, such as the lanthanoid sulfates. Lithium sulfate crystals, being piezoelectric, are also used in ultrasound-type non-destructive testing because they are very efficient sound generators. However they do suffer in this application because of their water solubility. ZINC NITRATE: Zinc nitrate (Zn(NO3)2) is a chemical compound used as a mordant in dyeing. It is also a source of zinc ions for chemistry. An example reaction gives a precipitate of zinc carbonate:Zn(NO3)2 + Na2CO3 → ZnCO3 + 2 NaNO3. Conditions/substances to avoid are: reducing agents, organic materials, metal powders, heat and flame, cyanides, sodium hypophosphite, tin(IV) chloride, phosphorus, thiocyanates, carbon, and sulfur. Its Relative Molecular Mass is 189. SODIUM PHOSPHATE: Sodium phosphate are forms of phosphorus, which is a naturally occurring substance that is important in every cell in the body. Sodium phosphate is used to treat constipation and to clean the bowel before surgery, x-rays, endoscopy, or other intestinal procedures. Sodium phosphate enemas are also used for general care after surgery and to help relieve impacted bowels. Sodium phosphate may also be used for other purposes not listed in this medication guide REGARDS, PNT.
Q:What is the relationship between electronegativity and the solubility of a inorganic salts?
The higher the electronegativity, the stronger the acid would be... Therefore it would be more soluble. take NaCl (common table salt) as an example. The difference between Na's electronegativity and Cl's electronegativity is very high so NaCl is a very soluble salt. The only exception is HF - it is a weak acid - it dissociates very weakly because O-H bonds cannot break H-F bonds which are very strong.
