Question 16
Easy

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→Al2​O3​

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​→Al2​O6​

4Al+3O2→2Al2O34\text{Al} + 3\text{O}_2 \rightarrow 2\text{Al}_2\text{O}_34Al+3O2​→2Al2​O3​
