Question

iron burns in oxygen to produce iron(ii) oxide. write a complete balanced equation for this reaction. what type of reaction is it?

Answer 1

Solution:-

Formula of the iron (ll) oxide = FeO

so as described iron (Fe) is reacting with oxygen(O2) to produce iron (ll) oxide (FeO)

so lets write the balanced reaction equation for the reaction

Fe+O2 ----- > FeO              unbalanced equation

so to balance the equation we need to use 2Fe so that it can produce 2 FeO which balanced both Fe and O on both sides of the equations following is the balanced reaction equation.

2Fe(s) +O2(g) ------ >2 FeO (s)        Balanced reaction equation

Here oxidation state of the Fe changes from 0 to +2 and oxidation state of the oxygen changes from 0 to -2

therefore Fe is oxidized and O is reduced. So this is the redox type reaction.
