Given the incomplete equation:
4fe + 3o2 ==> 2x
which compound is represented by x?
(1) feo (3) fe3o2
(2) fe2o3 (4) fe3o4

X represents the compound Fe2O3

The compound formed must possess all the above atoms, the samw amound, therefore: 2X=4Fe+6O; x=2Fe+3O; x=Fe2O3; Number two. If you notice any mistake in my english, please let me know, because i am not native.

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom

Anions are negative charged ions
