Question

Fill in the coefficients that will balance the following reaction: a0Fe + a1O2 → a2Fe2O3

Answer 1

A0=4
a1=3
a2=2
4Fe + 3O2 —> 2Fe2O3

Answer 2

Answer: $a_0=4$

$a_1=3$

$a_2=2$

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The balanced chemical equation for the given reaction is:

$4Fe+3O_2\rightarrow 2Fe_2O_3$

$a_0=4$

$a_1=3$

$a_2=2$
