What is the scientific name for feldspar?
Feldspar is not a specific substance, but a class of aluminosilicates of potassium, sodium and calcium.
What is a sodium an calcium feldspar with twinning striations called?
Plagioclase.
What element makes up feldspar?
It depends on the type of feldspar. Potassium Feldspar (also called K-Spar), contains potassium, aluminum, silicate: KAlSi3O8. Plagioclase Feldspar, on the other hand, contains calcium or sodium, aluminum, and silicate: NaAlSi3O8 or CaAl2Si2O8.
What is the dencity of feldspar?
It varies from 2.52 - 2.74 grams/cc (Orthoclas=2.52 Anorthite=2.74) The density varies to heavier with greater amounts of Sodium or Calcium and lighter for Potassium Feldspar (Orthoclase)
What are the types of feldspar?
There are broadly three main types of feldspars: calcium, sodium and potassium. They have the following general chemical formulas:KAlSi3O8 - NaAlSi3O8 - CaAl2Si2O8The endmember mineral states are known as K-Feldspar, Albite and Anorthite which are the potassium, sodium and calcium feldspars respectively.There can be a mix of calcium and sodium (more correctly termed solid solutions) in Feldspars between Albite and Anorthite which are known generally as Plagioclase feldspars.For more information please see the related question

Does sodium chloride contain calcium chloride?
Pure sodium chloride doesn't contain calcium chloride.
Is calcium in salt?
Sodium chloride doesn't contain calcium. Calcium chloride contain calcium.
Is there calcium in salt?
Sodium chloride doesn't contain calcium. Calcium chloride contain calcium.
What is sources of calcium and sodium in oceans?
Ocean water contain sodium and calcium chlorides.
What element makes up feldspar?

What happens when carbonic acid is mixed with feldspar?
Feldspar, a major constituent of most igneous rocks, reacts with carbonic acid to produce residual clay minerals plus dissolved ions of metals (potassium, sodium or calcium, depending on the type of feldspar). Here, for example, is the reaction by which potassium feldspar is converted to kaolinite, a clay mineral: 4KAlSi3O8 + 4H2CO3 + 2H2O → Al4Si4O10(OH)8 + 4K+ + 4HCO3- + 8SiO2 feldspar + carbonic acid + water → kaolinite + dissolved potassium and bicarbonate ions + dissolved silica Similar reactions affect sodium feldspar and calcium feldspar.

What is feldspar's chemical formula?
x Al(Al,Si)3O8, where x can be sodium (Na) and/or calcium (Ca) and/or potassium (K).
