Hydrated substances are formed by water absorption in the anhydrous substance.
After chemical reactions new substances are obtained.
Because after a chemical reaction new substances are obtained, with new properties.
Three substances obtained from common salt are sodium chloride (table salt), bleach (sodium hypochlorite), and baking soda (sodium bicarbonate).
Hydrated lime is not typically used as an absorbent material. It is commonly used in construction, agriculture, and water treatment for its chemical properties, such as neutralizing acidic soils and treating wastewater. Absorbent materials, on the other hand, are substances that take in liquids or gases.
"mineral" ;p
You might be thinking of hydrated salts. Examples include hydrated Copper Sulfate (CuSO4 . 5H2O)
The anagram is "gypsum" (hydrated calcium sulfate).
Practically (exceptions exist) all known substances can be obtained in a pure fom.
After chemical reactions new substances are obtained.
Heating hydrated sodium carbonate powder to remove water molecules is a physical change because it does not change the chemical composition of the substance. The process involves a phase change from solid to liquid (water loss) and does not result in the formation of new substances.
A new substance is obtained.
Because after a chemical reaction new substances are obtained, with new properties.
There is no one kind of ore for each metal, since the metal can be found in combination with various substances. That said, iron is usually obtained from hematite, aluminum from bauxite, and copper from chalcopyrite.
Three substances obtained from common salt are sodium chloride (table salt), bleach (sodium hypochlorite), and baking soda (sodium bicarbonate).
When from two substances is obtained a new substance the reaction is called synthesis.
Salts are compounds obtained after the reaction between an acid and a base.
Neon is usually found in the Earth's atmosphere. It is obtained through a process called fractional distillation after it has been liquefied.
