What is the chemical solution for hydronium?
The chemical formula for hydronium is H3O+. It is formed when an extra proton (H+) attaches to a water molecule (H2O). Hydronium is an important species in acidic solutions.
Does the large intestine store excess material?
It does not store excess material the rectum does that.
When something has a positive charge it has an excess of what elementary particles?
It lacks electrons rather then having an excess of elementary particles, but basically it's an excess of protons.
What is the medical term meaning excess of fat in feces?
Steatorrhea is excess fecal fat.
What is excess equipment?
Computer equipment becomes excess and is available for reuse when no longer needed for the purpose for which it was acquired.
What is observe when aqueous ammonia is added in excess to a silver chloride solution?
The white precipitate of silver chloride will dissolve when aqueous ammonia is added.
How do you dispose the excess bromine and other reagent containing bromine at the end of your experiment?
down the sink
Why should excess bromine water be avoided in the test for free tryptophan?
The presence of excess bromine water will cause the pink color to disappear and it may be masked by the color of the reagent.
What means aqueous?
Aqueous means large excess of water. when we write the worf aq with a substance in a chemical reaction it means that the substance formed is dissolved in water. For eg- CaO(s) + H2O(l) -------> Ca(OH)2 (aq)
What is the name for a solution that has an excess of H plus ions and therefore breaks into H plus and another compound when placed in an aqueous solution?
acid or acidic
What is the reaction of phenol with Bromine?
The hydroxyl group in phenol is an activating ortho/para director, but has some slight steric hindrance too ortho position substitution. Therefore, the predominant product of reaction between phenol and bromine will be 4-bromophenol, if reaction conditions are carefully controlled. With excess bromine, di- and tri-bromo phenols will be formed.
Explain how it is possible for Bromine to have a mass of 79.9 amu on the periodic table but NOT have a naturally occurring isotope with a mass of 80 amu?
This occurs because bromine has stable isotopes of mass 79 and 81. There is a slight natural excess of the lighter isotope, so that the average is 79.9.
Precipitate of salicylic acid dissolves after addition of excess sulphuric acid?
Serious need thus exists in this art for the improved precipitation and purification of salicylic acid from such aqueous solutions.
How does an implant lower intraocular pressure?
excess aqueous fluid is shunted through the tubing of the implant, and passes through the space that develops between the bleb and the plate. By diffusion, the fluid flows into the capillaries where it exits the eye
Aqueous phosphoric acid and aqueous calcium hydroxide react form solid calcium phosphate and water what is the balanced chemical equation for this reaction?
3 Ca(OH)2 + 2 H3PO4 --> Ca3(PO4)2 +6 H2O Note: Ca(OH)2 is not very soluble in water but enough to react with the acid, but may be some excess will be needed
How can you prepare ferrous oxalate?
Add ferrous chloride solid to saturated aqueous solution of oxalic acid then to expel the HCl gas then saturated solution is allow to cool the crystals of ferrous oxalate settled down with in few minutes remove the excess liquid and get the dry compound.
Calculate the mass of AgBr is formed when 35.5mL of 0.184 M AgNO3 is treated with an excess of aqueous hydrobromic acid HBr?
The mass of solid AgBr that is produced when 100.0 ml of 0.150 M AgNO3 is added to 20.0 ml of 1.00 M NaBr 2.82g.
