Final answer:
The correct balanced chemical equation for aluminum and oxygen producing aluminum oxide is 4Al + 3O₂→ 2Al₂O₃, ensuring equal numbers of atoms for each element on both sides.
Step-by-step explanation:
The correct way to balance the chemical equation for aluminum and oxygen producing aluminum oxide (Al+O₂→Al₂O₃) is option A: 4Al + 3O₂→ 2Al₂O₃. This balanced equation maintains the law of conservation of mass, indicating that there are equal numbers of each type of atom on both sides of the equation.
In this case, there are 4 aluminum atoms and 6 oxygen atoms on each side. The balanced equation also correctly represents the stoichiometry of the reaction, showing that 4 moles of aluminum react with 3 moles of oxygen to produce 2 moles of aluminum oxide.
