Aluminium metal reacts with oxygen gas to form solid aluminium oxide.
What is the balanced symbol equation for this reaction?
2Al+3O→Al2O32\text{Al} + 3\text{O} \rightarrow \text{Al}_2\text{O}_32Al+3O→Al2O3
Al+O2→AlO2\text{Al} + \text{O}_2 \rightarrow \text{AlO}_2Al+O2→AlO2
2Al+3O2→Al2O62\text{Al} + 3\text{O}_2 \rightarrow \text{Al}_2\text{O}_62Al+3O2→Al2O6
4Al+3O2→2Al2O34\text{Al} + 3\text{O}_2 \rightarrow 2\text{Al}_2\text{O}_34Al+3O2→2Al2O3
