the chemical equation of aluminium and iodine is given a s follows :2Al +3 I -> Al 2 I 3.
This is a balance eqaution .
aluminium oxide
Aluminium Iodide (AlI3)
2Al + 3CuCl2 --> 3Cu + 2AlCl3
I2 is the chemical formula for iodine. It is a diatomic solid.
The difference between chemical compounds and simple mixtures is that chemical compounds feature two or more atoms that are chemically bonded together. The elements in the chemical compound cannot be separated by "non-chemical" means; physicalmethods won't separate them. Mixtures can be separated without using chemical methods. Let's look at an example with iron and iodine. If we mix iron and iodine, the iron can be "sorted out" from the iodine with a magnet. The magnetic iron particles will be attracted to the magnet, and the iodine will not. That's because the two elements are not bonded together in the mixture; they're just "mixed" together. In the compound iron iodide, however, the iron atoms are bonded to iodine atoms. A magnet cannot be used to separate the two substances in the chemical compound we know as iron iodide. Only a chemical reaction can divide the molecules into their elemental constituents.
2Al + 3I2 -> 2AlI3
aluminium oxide
Aluminium Iodide (AlI3)
cai2
Aluminium is 'Al' Iodine is 'I' As a chemical salt they are 'AlI3'.
Aluminium + Iodine ----> Aluminium iodide2 Al + 3 I2 ----> 2 AlI3
Iodine
2Na + I2 --> 2NaI
2Mg + I2 ----> 2MgI
2Al + N2 ----> 2AlN
This equation is I2 (s) + 4 Cl2 (gas) => 2 ICl4 (s).
33CaO + 14Al = 12CaO · 7Al2O3 + 21Ca + Q
