Iodine Pentachloride
Its better name is Carbon dioxide = CO2
The formula of a compound called methane is CH4. This formula shows, among many other things, that there are four times as many hydrogen atoms as carbon atoms in methane and that each molecule contains 5 total atoms.
The prefix tri- means 3 and the prefix tetra- means 4. The prefix is the subscript number for the element in the compound. So the formula for triphosphorus tetrabromide is P3Br4.
C10H18. However, the compound is named incorrectly; it should be 5-ethyl-3-octyne.
It would be named as triphosphorus pentoxide. The prefixes tri and penta denote 3 and 5 respectively. So from the name, you would know that in one molecule or formula unit there are 3 P atoms and 5 O atoms.

PO3+ is the formula of an ion known as Phosphoryl ion. Here Phosphorus is in +5 oxidation state.
The formula of a compound called methane is CH4. This formula shows, among many other things, that there are four times as many hydrogen atoms as carbon atoms in methane and that each molecule contains 5 total atoms.
N2O5 ( di=2, penta=5)
Chlorophyll is not an element. it is a compound. It has 55 carbons, 72 hydrogens, 1magnesium, 4 nitrogen and 5 oxygen elements in it. Its' formula is C55H72MgN4O5.
The prefix tri- means 3 and the prefix tetra- means 4. The prefix is the subscript number for the element in the compound. So the formula for triphosphorus tetrabromide is P3Br4.
C10H18. However, the compound is named incorrectly; it should be 5-ethyl-3-octyne.
CaTe is the chemical symbol of calcium telluride.
It would be named as triphosphorus pentoxide. The prefixes tri and penta denote 3 and 5 respectively. So from the name, you would know that in one molecule or formula unit there are 3 P atoms and 5 O atoms.
Phosphorus pentachloride
the formula does not show how many moles are in a compound, but it tells how many atoms of an element that are in the compound...
