Potassium feldspars are common members of the alkali feldspar group and form a complete solid solution series from KAaSi3O8 through (K, Na)AlSi3O8 to NaAlSi3O8. You really need more information for a precise chemical composition as K-Feldspars can have a wide range of chemical compositions.
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
Sandstone will often contain feldspar, but some sandstones are composed entirely of quartz.
The most common class of minerals is the silicate minerals, which make up over 90% of the Earth's crust. Silicate minerals contain silicon and oxygen atoms in their chemical structure, and they form various types of minerals such as quartz, feldspar, and mica.
Quartz is the most abundant mineral among feldspar, mica, and calcite. It is a common mineral found in a wide variety of rock types and environments worldwide.
The four major rock-forming minerals are quartz, feldspar, mica, and amphibole. These minerals are commonly found in various types of igneous, sedimentary, and metamorphic rocks and make up a significant portion of the Earth's crust.

Yes, certain types of feldspar, such as amazonite or moonstone, can exhibit a blue coloration due to the presence of trace elements like lead or potassium in their chemical composition. The blue shades in feldspar are often a result of light interference or structural features, rather than a true inherent blue color.
The energy source for a battery is chemical energy, which is stored in the battery's electrolyte and electrodes. When the battery is connected to a circuit, chemical reactions occur, converting this stored chemical energy into electrical energy. This process generates a flow of electrons, providing power to devices. Different battery types use various chemical compositions to optimize performance and energy capacity.
There is no formula. There are different types of detergent with different compositions. Even then most, if not all detergents are mixtures, and mixtures do not have chemical formulas.
The continuous reaction series primarily involves the mineral groups of feldspars and amphiboles, which represent the gradual transition from mafic to felsic compositions. As magma cools, minerals crystallize in a specific order: olivine, pyroxene, amphibole, and biotite, followed by feldspars, muscovite, and quartz. This series illustrates the progressive change in mineral composition based on temperature and chemical environment during crystallization. The continuous nature of the series reflects the range of compositions within the feldspar and amphibole families, allowing for a spectrum of mineral types rather than distinct categories.

The most common class of minerals is the silicate minerals, which make up over 90% of the Earth's crust. Silicate minerals contain silicon and oxygen atoms in their chemical structure, and they form various types of minerals such as quartz, feldspar, and mica.
Minerals that do not contain silicon are classified as non-silicate minerals. This group includes various mineral types such as carbonates, oxides, sulfates, and halides. Non-silicate minerals can have diverse chemical compositions and structures, making them significant in various geological and industrial applications. Examples include calcite (a carbonate) and hematite (an oxide).

The person who first found feldspar rocks is unknown, however, these types of rocks are commonly found in the Earth's crust and along road cuts of Ontario. Feldspar is commonly found in granite.
