Balance this equation, Al_(2)O_(3)... Al+O_(2) 2Al_(2)O_(3)arrow 4Al+3O_(2) Cannot be balanced 2Al_(2)O_(3)arrow 2Al+3O_(2) 3Al_(2)O_(3)arrow 2Al+O_(2)

The correct answer is: $2Al_{2}O_{3}\rightarrow 4Al+3O_{2}$<br /><br />Explanation:<br />To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation.<br /><br />In the given equation, we have:<br />$Al_{2}O_{3}\cdots Al+O_{2}$<br /><br />To balance the equation, we need to multiply the coefficients of the reactants and products to ensure that the number of atoms of each element is the same on both sides.<br /><br />The balanced equation is:<br />$2Al_{2}O_{3}\rightarrow 4Al+3O_{2}$<br /><br />In this balanced equation, we have:<br />- 4 aluminum atoms on both sides<br />- 6 oxygen atoms on both sides<br /><br />Therefore, the correct answer is $2Al_{2}O_{3}\rightarrow 4Al+3O_{2}$.
