Sorry, haven't came across that as of yet.
False, because new information is being discovered all the time so they add the new information to the models to make them accurate.
The answer is
decomposition
Answer:
Fe2O3, Fe2S3 and FeCl3
Explanation:
The formular shows the number of atoms of element present in the compound. The number of atoms in turn depends on the charges. The goal is to have a neutral compound with oxidation number of zero.
Oxide:
Iron(Fe) has oxidation number (O.N) of +3, oxygen has O.N of -2. The formular with a balanced (Charge = 0) O.N number is; Fe2O3
Sulphide:
Iron(Fe) has oxidation number (O.N) of +3, sulphur has O.N of -2. The formular with a balanced (Charge = 0) O.N number is; Fe2S3
Chloride:
Iron(Fe) has oxidation number (O.N) of +3, chlorine has O.N of -1. The formular with a balanced (Charge = 0) O.N number is; FeCl3
