What element is a halogen whose crystals sublime?
Iodine is a halogen whose crystals sublime. When iodine is heated, it changes directly from a solid to a gaseous state without passing through a liquid phase.
How are crystals different from rocks?
A crystal is a structure. A mineral is a material. A crystal is a regular arrangement of atoms, ions, or molecules in a solid. This regular internal structure leads to a geometrically regular external shape. Sodium chloride (common salt) crystals, for example, are cubic. A mineral is any element or compound, normally occurring naturally as crystals. Rocks consist of two or more minerals.
Is urea an organic compound or inorganic?
Urea is an organic compound because it contains carbon atoms covalently bonded with other elements like nitrogen and oxygen. It is produced in living organisms as a waste product of protein metabolism.
What is the process called to form urea?
Diazolidinyl urea is produced by the chemical reaction of allantoin and formaldehyde in the presence of sodium hydroxide solution and heat. The reaction mixture is then neutralized with hydrochloric acid and evaporated. Note: Diazolidinyl urea is an antimicronbial preservative used in cosmetics. It is chemically related to imidazolidnyl urea which is used in the same way. Diazolidinyl urea acts as a formaldehyde releaser. Commercial diazolidinyl urea is a mixture of different formaldehyde addition products including polymers. source: http://en.wikipedia.org/wiki/Diazolidinyl_urea
What is nh2conh2?
NH2CONH2 is the chemical formula for urea, a compound found in urine and used in fertilizers, cosmetics, and as a raw material for plastics and resins. It is produced in the liver as a way to remove excess nitrogen from the body.
What is an important element in urea?
Nitrogen is the primary element in urea [CO(NH2)2], along with carbon, oxygen, and hydrogen.
When precipitating calcium oxalate what is the purpose of adding urea?
Urea is added when precipitating calcium oxalate to increase the solubility of the calcium oxalate crystals. This helps to prevent the formation of large, dense crystals that can be difficult to filter and wash. By adding urea, smaller and more easily filterable crystals are formed.
Is crystals a element?
Simply put, no.
How do you make ice crystals on alxemy?
To make ice crystals in Alxemy, combine the elements of water and cold. Place the water element on the cold element to create ice crystals.
Is iodine crystals an element compound or mixture?
Iodine is a chemical element; not a mixture, not a compound.
What element makes crystals green?
phosphorous
What Compound contains the element nitrogen?
urea, ammonia, amino acids, and many more
What does iodine mean Or what is iodineThe chemical element of atomic number 53, a non-metallic element forming black crystals and a violet vapour?
The chemical element of atomic number 53, a non-metallic element forming black crystals and a violet vapour.
Why sugar crystals grow faster than salt crystals?
Salt is a more cubic element than sugar
Is copper sulfate crystals a mixture or an element?
Neither, coper sulfate is not a mixture and it is not an element. Coper Sulfate is a chemical compound.
Are crystals broken down a compound or an element?
Compound, crystal is not an element so obviously what it is made up of must be a compound <><><><> Crystals can be either an element (diamonds are carbon- and crystalline) or a compound (salt, sugar). Unsure of your meaning of "broken down".
Is the crystal element or compound?
Crystals can be elements (as diamond) or compounds (as sapphire).
