Types of minerals?
There are two basic types of mineral. 1. Macro -- It is the amount mineral needed by the body which is larger than 100 milligrams. Examples: Calcium, phosphorus and magnesium 2. Trace-- It is the amount needed by the body in small amounts Example: Iron 3.Gypsum--a common white or colorless mineral (hydrated calcium sulphate) used to make cements and plasters (especially plaster of Paris) Gypsum is a very soft mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4·2H2O. A common mineral of evaporates in inland salt playas. Calcium sulphate the raw material (minerals alabaster, satin spar, selenite) used for gypsum plasters, wallboard/drywall; gypsum plaster, unlike cement, expands on setting, does not crack unless there are faults in the backing; must never be mixed with Portland cement.
What is Hydration of minerals?
•Metasomatism •Serpentinization: • •3Mg2SiO4 + 4H2O + SiO> 2Mg3Si2O5(OH)4 •3Fe2SiO4 + 2H2O > 2Fe3O4 + 3SiO2 + 2H2
Reaction between strontium carbonate and sulfuric acid?
The products of this reaction are strontium chloride, carbon dioxide and water.
Contrast synthesis and decomposition reactions?
In a synthesis reaction two or more simple substances combine to form a more complex substance. Two or more reactants yielding one product Ex) H2 + 1/2O2 --> H2O Decomposition: a complex substance breaks down into simple substances. Ex) 2H2O --> 2H2 + O2
What is gypsum dihydrate?
CaSO4 = gypsum CaSO42H2O = Gypsum Selenite 2H2O =Selenite
What is the chemical name and formula for gypsum?
Gypsum, common mineral consisting of hydrated calcium sulfate (CaSO4·2H2O).
What is natural gypsum?
CaSO4 . 2H2O
What is chemical formula of a gypsum?
Gypsum's chemical formula is CaSO4·2H2O.
What is the formula and chemical name of gypsum?
CaSO4 2H2O
What is the name of the chemical sedimentary rock whose mineral composition can be written as hydrous calcium sulfate?
Gypsum (CaSO4·2H2O).
Is gypsum a compound or mixture?
Gypsum is a compound. It is a soft sulfate mineral composed of calcium sulfate dihydrate (CaSO4·2H2O.CaSO4·2H2O). The word gypsum comes from the Greek word meaning chalk or plaster, two of its most common uses.
What hydrate is CaSO4 2H2O?
Calcium Sulfate Dihydrate, aka Gypsum.
Chemical name of Plaster of paris?
Calcium sulphate hemihydrate, CaSO4.1/2H2O
Are sulfates and sulfides types of nonsilicate minerals?
Gypsum is not a silicate it is a sulfate. Gypsum is a very soft mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4·2H2O
What is the difference between Gypsum and Anhydrite?
Anhydrite is formed from dehydrated gypsum or to make it easier to understand when water is added to anhydrite it becomes gypsum as we can see from their chemical formulas [Anhydrite (CaSO4) and Gypsum (CaSO4-2H2O)].
What is the difference between halite and gypsum?
Halite is common salt, sodium chloride (NaCl). Gypsum is calcium sulfate (CaSO4·2H2O).
