Balance the f...

Question

Balance the following equation:
a) $F e + H_{2} O \to F e_{3} O_{4} + H_{2}$

Open in App

Solution

The skeletal equation is:
$F e + H_{2} O \to F e_{3} O_{4} + H_{2}$

To equalize oxygen, multiply H2O by 4.

$F e + 4 H_{2} O \to F e_{3} O_{4} + H_{2}$

To equalize Fe, multiply it by 3.

$3 F e + 4 H_{2} O \to F e_{3} O_{4} + H_{2}$

To equalize Hydrogen, multiply by 4.

$3 F e + 4 H_{2} O \to F e_{3} O_{4} + 4 H_{2}$
The equation is balanced.
