Question

Coefficient of balanced equation: __Fe + ___020) — _Fe_036)

Answer 1

Answer:

- Four for iron, three for oxygen and 2 for iron (III) oxide:

$4Fe+3O_2\rightarrow 2Fe_2O_3$

Explanation:

Hello,

In this case, the oxidation of iron is a widely acknowledged reaction occurring in ships and other machines exposed to the air or highly oxidizing medias. Thus, by the effect of oxygen, iron undergoes oxidation typically to iron (III) oxide:

$Fe+O_2\rightarrow Fe_2O_3$

Nonetheless, the law of conservation of mass must be respected, therefore the coefficients balancing the reaction are four for iron, three for oxygen and 2 for iron (III) oxide:

$4Fe+3O_2\rightarrow 2Fe_2O_3$

Best regards.
