Answer:
4Al +3O₂ → 2Al₂O₃
Explanation:
To balance the chemical equation, start by identifying the number of atoms of each element on both sides of the equation.
Al +O₂ → Al₂O₃
<u>Reactants</u> (right-hand side of the arrow)
Al➭ 1
O➭ 2
<u>Products</u> (left-hand side of the arrow)
Al➭ 2
O➭ 3
Balancing the equation means that we need to ensure the number of atoms of each element is the same on both sides of the equation.
Let's balance the number of O atoms.
Al +3O₂ → 2Al₂O₃
<u>Reactants</u>
Al➭ 1
O➭ 3(2)= 6
<u>Products</u>
Al➭ 2(2)= 4
O➭ 2(3)= 6
Balancing the number of Al atoms:
4Al +3O₂ → 2Al₂O₃
<u>Reactants</u>
Al➭ 4
O➭ 6
<u>Products</u>
Al➭ 4
O➭ 6
The equation is now balanced.
