Sulfur forms compounds in oxidation states −2 (sulfide, S2−), +4 (sulfite, SO32−), and +6 (sulfate, SO42−). I don't know what type of ion but hope this helps!! :)
The first one is unbalanced, the photo below is proof.
Then there should be mostly 91 nails
When iron loses the 2 4s electrons, it attains a valency of +2. Sometimes, iron will also lose one of the paired electrons from 3d orbital, leaving the entire 3d orbital filled with unpaired electrons (which provides a more stable configuration). In this case, its valency will be +3.
Answer:
There are three nitrogen atoms in the products. The law of conservation of mass states that the amount of substance should be the same before and after a reaction. ... balanced because the total number of oxygen atoms is 3.
