Question

What is the balanced equation for Fe+O2—->Fe3O4

Answer 1

Answer:

The balanced chemical reaction is:

$3Fe+2O_2\rightarrow Fe_3O_4$

Explanation:

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

While balancing the chemical equation balance all the atoms of elements except oxygen atom which will be done in the last.

$Fe+O_2\rightarrow Fe_3O_4$

Step 1: Write three in front of iron;

$3Fe+O_2\rightarrow Fe_3O_4$

Step 2: Now write two in front of oxygen gas;

$3Fe+2O_2\rightarrow Fe_3O_4$

The balanced chemical reaction is:

$3Fe+2O_2\rightarrow Fe_3O_4$

According to reaction, 3 moles of iron reacts with 2 moles of oxygen gas to give 1 mole of ferric oxide.

Answer 2

Answer:

3Fe2O2---> Fe3O4

Explanation:

You need to add three to the left side to make it equal to the one on the right, and add a 2 since you can't change the subscripts
