Question

For the below equation, balance and determine the ratios listed below:

Answer 1

The balanced chemical equation is:

- Ratio of Al2O3 to O2: 2:3R

- Ratio of Al2O3 to Al: 2:4R

- Ratio of Al to O2: 4:3R

Step-by-step explanation:

To balance the chemical equation, it is necessary to have the same amount of elements on the reactant side as on the product side:

`2Al_2O_3\rightarrow4Al+3O_2`

Now we know that the reaction is balanced, because on the reactant side and on the products side there are:

- 4 Al

- 6 O

Now that the equation is balanced, we can write the ratios with the stoichiometry of the reaction.
