Silicic acid
Mafic rock is on average more dense.
Rhyolites are formed by the solidification of silicic magma on the earth surface. They are the extrusive equivalent of Granite.
Eruptions involcing silicic or felsic magma are generally the worst. Eruptions of mafic material are usually effusive or only mildly explosive, producing cinders or lava flows. Eruptions of felsic material often produce large ash clouds and deadly pyroclastic flows.
No. Some igneous rocks were once referred to as "acidic" on the misconception that they contained elevated levels of silicic acid.
The chemical formula of silicon dioxide is SiO2.
By rubber, low-density, diatom polyethylene, diatom frustules (largely silicic acid), and PFTE (Teflon).
silicate is a combination of silicon, oxygen and other element such as aluminium while silicone is made up of many compounds, silicon is chemical element which cannot be divided into other simple substances without splitting atoms, silicic and siliceous are compounds formed from silicon and other elements
Chlorine (Cl) is much more electronegative than silicon (Si). This means that chlorine exerts a much stronger "pull" on the electrons in a perchloric acid molecule than silicon does in a silicic acid molecule. The stronger pull makes it easier for a hydrogen ion (H+) to break away. The greater the degree of dissociation the stronger the acid. Perchloric acid dissociates completely in water, thus marking it as a strong acid. Silicic acid only dissociates partially, thus marking as a weak acid.
Silicic acid could occur as solution as well as solids. Silicic acid, a compound of silicon, oxygen, and hydrogen, regarded as the parent substance from which is derived a large family-the silicates-of minerals, salts, and esters. The acid itself, having the formula Si(OH)4, can be prepared only as an unstable solution in water; its molecules readily condense with one another to form water and polymeric chains, rings, sheets, or three-dimensional networks that constitute the structural units of silica gel and many minerals that have very low solubility in water.
they produce silicous rocks(chert).unlike foramaniferas produces limestone caco3
