Which type of chemical formula is the most informative?
Displayed - shows all the bonds and all the elements in the order which they occur
A structural formula is a type of chemical formula, differing from a simple formula. The simple formula for Glucose, for example, is C6H12O6, and only says what is in that substance. The structural formula is a general sketched map of the elements and where they bond. Try googling a picture of the Glucose structural formula to see what I mean.
Well, generally a formula is a group of symbols that make a mathematical statement. In chemistry, chemical formula or molecular formula is a way of expressing information about the atoms that constitute a particular chemical compound. For example formula of Sodium hydroxide is (NaOH), formula of methane is (CH4) etc. -or- A chemical formula is a concise way of expressing information about the atoms that constitute a particular chemical compound. It identifies each type of…
If "kallium" in the questions was intended to be "kalium", the Latin name for potassium, the formula of the most common type is is K3PO4, which is more exactly called potassium orthophosphate KPO2 is the formula for another compound that can be called "kalium" phosphate, more exactly metaphosphate. Either formula can also have water of hydration.
Does a chemical formula indicate the relative number of molecules of each kind in a chemical compound?
yes, for example H2O (water) there are 2 hydrogen molecules and 1 oxygen. There are other kinds of chemical formula, such as the empirical formula that give you the smallest ratio of atoms, for example glucose C6H12O6 (6 carbons 12 hydrogens and 6 oxygens) would be CH2O however it should state if the formula is any other type then just the normal chemical formula.
