Does silica contain carbon?
They do not normally. Their chemical formula is SiO2 (silicon dioxide). However, the different colours of quartz follow when there are impurities in the mineral, and so carbon could be an impurity which can cause a certain colour of quartz.
What are four chemical or substances silicon contains?
Silicon, silicon, silicon and silicon. Silicon is an element; it doesn't "contain" any other chemicals. If you absolutely insist on getting four things in there, you could say protons, neutrons, electrons and gluons, or up quarks, down quarks, gluons and electrons ... but that's stretching the meaning of "substance" a bit.
What is the atomicity of silicon?
Atomicity, what a charming old word. Used to mean either valency or the number of atoms in a molecule. For silicon the valency is 4. (where valency was the numebr of bonds that could be formed) Silicon is not molecular, it is normally encountered as a solid with a network lattice.
Where did silicon get its symbol?
If it were Qz, I could understand the question, but the symbol for silicon is Si ... what part of this is confusing?
Where can silicon be found?
Pure silicon cannot be found in nature but is found in a number of compounds. These compounds are usually oxides, and silicon oxides are found as sand and as silicate minerals. Silicon makes up about a quarter of the earth's crust, so there is plenty of it to go around. Silicon is a nonmetallic element and very abundant in nature. Its atomic number is 14. Silicon was discovered by Jöns Jacob Berzelius, a Swedish chemist, in 1824 by heating chips of potassium in a silica container and then carefully washing away the residual by-products. Silicon is the seventh most abundant element in the universe. Today, silicon is produced by heating sand (SiO2) with carbon to temperatures approaching 2200°C. Silicon is also is A non-metallic element occurring extensively in the earth's crust in silica and silicates, having both an amorphous and a crystalline allotrope, and used doped or in combination with other materials in glass, semi-conducting devices, concrete, brick, refractories, pottery, and silicones. There is a Latin word in silicon called 'silex' meaning flint in Latin. Silicon is classified as a "Metalloid" element and is located in Groups 13, 14, 15, 16 and 17 of the Periodic Table. An element classified as a Metalloid has properties of both metals and non-metals. Some are semi-conductors and can carry an electrical charge making them useful in calculators and computers. Silicon was first identified by Antoine Lavoisier in 1787. Re-discovered by Jons Berzelius in 1823. The high-tech region of Silicon Valley, California, is named after this element. Silicon is presented in the sun and stars. Silicon forms other useful compounds. Silicon carbide (SiC) is nearly as hard as diamond and is used as an abrasive. Sodium silicate (Na2SiO3), also known as water glass, is used in the production of soaps, adhesives and as an egg preservative. Silicon tetrachloride (SiCl4) is used to create smoke screens. Silicon is also an important ingredient in silicone, a class of material that is used for such things as lubricants, polishing agents, electrical insulators and medical implants.
How could separate zinc chloride from silicon oxide?
Zinc chloride is very soluble in water and silicon dioxide is not soluble. - Put the mixture of ZnCl2 and SiO2 in water - Wait for the dissolving of the ZnCl2 - Separate the two components by filtering
How many atoms does silicon dioxide contain?
Well, honey, silicon dioxide, also known as silica, contains one silicon atom and two oxygen atoms per molecule. So, if we're talking about a single molecule of silicon dioxide, it contains a total of three atoms. But if you're asking about a sample of silicon dioxide, well, that could contain trillions upon trillions of atoms depending on the size of the sample. Hope that clears things up for ya, sugar!
How is silicon useful for humans?
Silicon, as the dioxide, is the main component of glass. It has been suggested that silicon could be used as a fuel. First being reduced in solar furnaces near the equator, and then oxidized again at the energy consumption point.
Does silica contain carbon?
They do not normally. Their chemical formula is SiO2 (silicon dioxide). However, the different colours of quartz follow when there are impurities in the mineral, and so carbon could be an impurity which can cause a certain colour of quartz.
Can coal turn into sandstone?
No. Coal is largely carbon and is burned for fuel. The combustion products are largely carbon dioxide and water vapor, plus some gases like sulfur dioxide. After coal is burned, it leaves behind ash, which is the impurities in coal that can't burn at the temperatures at which coal is burned. The ash can contain some silicon dioxide that was in the coal as an impurity. Coal can be exposed to high pressure and heat that might transform the carbon in coal into other carbonaceous forms such as graphite or diamond. There is no process that could transform coal into silicon dioxide. Sandstone is sand (silicon dioxide) plus cementing agents and is not burnable, because it is itself the product of the burning of silicon and oxygen (called oxidation), just like wood ash is.

What is the compound name of SiC?
It could be named any one of monosilicon tetrafluoride, silicon tetrafluoride, or tetrafluorosilane.
How could you separate zinc chloride from SiO2?
Tellerium dioxide is not soluble in water or acid. Silicon dioxide on the other hand is soluble in Hydroflouric acid. Weigh your mixture of TeO2 and SiO2. Add HF acid. Allow the SiO2 to disolve. Decant your acid solution. Dry and weigh the remaining Te02
If you could break up a carbon dioxide molecule would you still have carbon dioxide?
No, breaking up a carbon dioxide molecule into its constituent atoms (carbon and oxygen) would result in separate carbon and oxygen atoms. The molecular structure and properties of carbon dioxide would no longer exist.
What is Si2Br?
You have described a fictitious chemical. When silicon combines with bromine it forms SiBr4 which is silicon tetrabromide. It does not combine in the ratio that your formula gives (which could be called disilicon bromide).
Is sand a covalent crystalline substance?
CovalentThe structure of silicon dioxide, SiO2Silicon dioxide is also known as silicon(IV) oxide.The giant covalent structure of silicon dioxideThere are three different crystal forms of silicon dioxide. The easiest one to remember and draw is based on the diamond structure.Crystalline silicon has the same structure as diamond. To turn it into silicon dioxide, all you need to do is to modify the silicon structure by including some oxygen atoms.Notice that each silicon atom is bridged to its neighbours by an oxygen atom. Don't forget that this is just a tiny part of a giant structure extending on all 3 dimensions.Note: If you want to be fussy, the Si-O-Si bond angles are wrong in this diagram. In reality the "bridge" from one silicon atom to its neighbour isn't in a straight line, but via a "V" shape (similar to the shape around the oxygen atom in a water molecule). It's extremely difficult to draw that convincingly and tidily in a diagram involving this number of atoms. The simplification is perfectly acceptable.The physical properties of silicon dioxideSilicon dioxidehas a high melting point - varying depending on what the particular structure is (remember that the structure given is only one of three possible structures), but around 1700°C. Very strong silicon-oxygen covalent bonds have to be broken throughout the structure before melting occurs.is hard. This is due to the need to break the very strong covalent bonds.doesn't conduct electricity. There aren't any delocalised electrons. All the electrons are held tightly between the atoms, and aren't free to move.is insoluble in water and organic solvents. There are no possible attractions which could occur between solvent molecules and the silicon or oxygen atoms which could overcome the covalent bonds in the giant structure.http://www.chemguide.co.UK/atoms/structures/giantcov.HTMLveryy helpfull for chemistryy =D
Is there Myths about silicon?
That silicon could possibly be the basis of an alternate bio-chemistry. In fact the 'organic' properties of Silicon are severly limited in comparison to Carbon and require very special and limited conditions to be valid in.
