Iron reacts with oxygen to produce iron oxide (rust). this reaction is represented in an equation as 4fe + xo2 → 2fe2o3. identify the value of x that will balance the equation.

The value of x  will be " 3 ".

Explanation:

The iron reacts with moist air and leads to formation of reddish brown layer on its surface that is rust .

It is corrosion but in case of iron is called as "rust ".

The conditions necessary for rusting is :

When iron comes in contact with moist air rusting occurs .

The chemical formula of rust is ; Fe₂O₃.x H₂O

The overall reaction can be represented as :

4 Fe + xO₂-->2  Fe₂O₃

we also know that , mass in any chemical reaction cant be created nor be destroyed ,it remains conserved .So,in accordance with Law of conservation of mass we balance the equation .

Therefore  , to balance oxygen we need to multiply it with 3 so as to equalize 6 moles on both sides .

god i hope this !
