Question

Need help!!!
Not sure if in right section, but I need help balancing equations

__Fe+ ___O2->__Fe2O3

Answer 1

2fe+ho2--->3feso3

Answer 2

@denisaboichuk How is that balanced if you have 2 Fe on the left and 6 on the right?

Answer 3

\[\huge \color{blue}8\text{Fe}+\color{blue}6\text{O}_2 \rightarrow \color{blue}4\text{Fe}_2\text{O}_3\]
On the left side we have:
8 Fe
12 O2
On the right side we have
8 Fe
12 O2

Looks good to me

Answer 4

Actually, we can reduce this to\[\huge \color{blue}4\text{Fe}+\color{blue}3\text{O}_2 \rightarrow \color{blue}2\text{Fe}_2\text{O}_3\]
