What is this balanced?<br> Al2O3---&gt; Al+O2
saveliy_v [14]

The balanced equation :

<em>2Al₂O₃⇒ 4Al+3O₂</em>

<h3>Further explanation</h3>

Given

Reaction

Al₂O₃⇒ Al+O₂

Required

Balanced equation

Solution

A chemical reaction is said to be balanced if the number of elements involved in the reaction is the same (either the reactants or the products)

The reaction above is said to be unbalanced because the number of elements Al and O in the reactants and products is not the same.

The balancing step

1. Give a coefficient

Al₂O₃⇒ aAl+bO₂

2. Make an equation

Al, left = 2, right = a⇒a=2

O, left = 3, right = 2b⇒2b=3⇒b=3/2

The equation becomes :

Al₂O₃⇒ 2Al+3/2O₂ x2

<em>2Al₂O₃⇒ 4Al+3O₂</em>
