A combination of elements Magnesium (Mg) and Silicon (Si) and 3 atoms of Oxygen (O). [I actually knew that from the top of my head... surprising...] I'm not sure of the exact name, but look around Wikipedia, and you might find it :] MgSiO3 is the formula for Enstatite, a rock forming mineral (common in igneous and metamorphic rock).
Anthracite coal has the highest percentage of carbon among the different types of coal.
'Sand' is the name for fine granules of rock and other minerals, and therefore does not have a standard molecular formula, as many different things can be counted as 'sand'. However most sand is in the form of silicon dioxide, SiO2, a molecule containing one atom of Silicon and two of Oxygen.
Silicon is a semi-metallic (or metaloid) element, with atomic number 14; it is found in many kinds of rock and minerals.
Coal. It is a black shiny rock. It is a solid twin to crude oil.
tiny particles from rock.
Yes.
The mantle has oxygen, silicon, aluminum, iron, calcium, sodium, potassium, magnesium, and titanium in it.
Quartzite is composed mostly of silica. It contains minerals like zircon, rutile, and magnetite, and the silica cements them together.
yes silicon is a rock
Silica is the mineral quartz (SiO2) and silicon is the element (Si) which is a major rock forming element in Earth's crust, and is therefore found nearly everywhere. Concentrations of silica which are mined are usually in the form of quartz sand or sandstone deposits.
Quartz is a mineral composed of silicon and oxygen, SiO2.
Silicates consist of Silicon and Oxygen, that may form with other compounds. Silicon bonds to Oxygen extremely easily. The chemical composition forms a perfect tetrahedron, SiO4. Silicon and Oxygen are also simply the most common elements found in the crust. Undergrad Geoscientist.
Most rock forming minerals are silicates because of the preponderance of the elements silicon and oxygen in the crust and mantle.
Most minerals on Earth are made up of silicon and oxygen.
It is silicon and oxygen that make up sand. Most sand is silicon dioxide, or SiO2. Quartz is the most common of a family of minerals made up of silicon dioxide called silicates. It is one example of a form of silicon dioxide.
The crust is mainly composed of rock. The rock of the crust is composed of silicon minerals. It also has great rates of oxygen in it.
