Different things for different prefixes. Meth, eth, prop, etc. are prefixes in organic chemistry that tell you that there are 1, 2, 3, etc. carbon atoms in a compound. Other prefixes mean other things. But you need to learn the rules for naming compounds, because there are exceptions. CO has just one carbon, but its name has nothing to do with the meth prefix. It is called carbon monoxide.
If you mean potassium Cyanide, the formula is KCN
There is no chemical with the formula AuC1. You most likely mean AuCl, which is gold I chloride.
Assuming that you mean Hydrogen, its formula is H2, hydrogen is diatomic molecule
The chemical formula for sugar, specifically glucose, is C6H12O6.
Cu represents the chemical element copper. Its chemical symbol comes from the Latin word "cuprum." The chemical formula for copper is Cu.
The formula for Heptasulfur Dioxide is S7O2.
The prefix di- means 2, and the prefix tetra- means 4, so the formula for diphosphorus tetrabromide is P2Br4.
H2F Di is the prefix for 2, so there are two hydrogen atoms and one fluorine atom. Hope that helps?
The prefix chem- means pertaining to chemistry. Two examples are chemical and chemoreceptive.
the prefix hexa stands for 6, so the formula would be XeCl6 ( the 6 is subscript)
I expect you mean, toluene, whose chemical formula is C7H8. Please see the link.
Well, tne chemical formula is MnO2. If you mean the name of it, that is manganese dioxide.
I assume that you mean sodium chloride, in which case the chemical formula is NaCl.
If you mean potassium Cyanide, the formula is KCN
Do you mean chemical formula? C12H22O11.
The formula for sulfur dibromide is SBr2. Bromide has the prefix di- which means two.
There is no chemical with the formula AuC1. You most likely mean AuCl, which is gold I chloride.
