Which is the balanced equation for the reaction of iron with oxygen to form Fe2O3\text{Fe}_2\text{O}_3Fe2​O3​?

[1]
A

2Fe+3O2→2Fe2O32\text{Fe} + 3\text{O}_2 \rightarrow 2\text{Fe}_2\text{O}_32Fe+3O2​→2Fe2​O3​

B

4Fe+3O2→2Fe2O34\text{Fe} + 3\text{O}_2 \rightarrow 2\text{Fe}_2\text{O}_34Fe+3O2​→2Fe2​O3​

C

3Fe+2O2→Fe2O33\text{Fe} + 2\text{O}_2 \rightarrow \text{Fe}_2\text{O}_33Fe+2O2​→Fe2​O3​

D

4Fe+6O2→2Fe2O34\text{Fe} + 6\text{O}_2 \rightarrow 2\text{Fe}_2\text{O}_34Fe+6O2​→2Fe2​O3​
