KAlSi3O8 and NaAlSi3O8
The general chemical formula of orthoclases is K(Na)AlSi3O8.
KAlSi3O8 and NaAlSi3O8
Orthoclase feldspar is a tectosilicate mineral which is most commonly found in igneous rock. It has a Mohs hardness of 6 and has two cleavage planes which occur at right angles to each other. It is the potassium endmember of the feldspar group of minerals and is also referred to as alkali feldspar or K-spar. Orthoclase will appear in colors from white to deep pink, but has a white streak.
There is no specific or universal chemical formula for slate, because slate is formed up of various amounts of varying types of rock such as:QuartzMuscoviteIlliteBiotiteChloriteHematitePyriteApatiteGraphiteKaolinMagnetiteTourmalineZirconFeldsparIn some locations, such as the mountains of Wales, slate also contains iron.Because of the range of diversity of which slate is formed from - there is no universally accurate formula for slate in general.
If you break down the chemical by it's elements and apply some simple rules, you can find the formula for a chemical compound.
H is the chemical formula for hydrogen. There are some elements with H in the chemical formula. But the have other letters too.
Orthoclase can typically be found in granite and igneous rocks. It is also commonly present in some metamorphic rocks.
Chemical weathering is the type of weathering that involves a chemical change in some of the minerals in a rock. This process breaks down the rock into smaller pieces by altering its mineral composition through chemical reactions with substances like water, oxygen, or acids.
soem examples of chemical sedimantery rock are limestone, and gypsum.
Some examples of chemical sedimentary rocks include limestone, dolostone, and rock salt. These rocks form when minerals precipitate out of a solution, such as when water evaporates or through processes like precipitation.
