Question 10
F

Aluminium reacts with oxygen to form aluminium oxide, Al2O3\text{Al}_2\text{O}_3Al2​O3​. Which is the balanced equation for this reaction?

[1]
A

Al+O2→AlO2\text{Al} + \text{O}_2 \rightarrow \text{AlO}_2Al+O2​→AlO2​

B

2Al+3O2→Al2O32\text{Al} + 3\text{O}_2 \rightarrow \text{Al}_2\text{O}_32Al+3O2​→Al2​O3​

C

2Al+O3→Al2O32\text{Al} + \text{O}_3 \rightarrow \text{Al}_2\text{O}_32Al+O3​→Al2​O3​

D

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