Question

directions: drag the answers to the correct boxes. balance the following equation using the lowest possible coefficients. fe + o₂ → fe₂o₃

Explanation:

Step1: Balance oxygen atoms

We have 2 oxygen atoms in \(O_2\) and 3 oxygen atoms in \(Fe_2O_3\). The least - common multiple of 2 and 3 is 6. So we put a 3 in front of \(O_2\) and a 2 in front of \(Fe_2O_3\): \(Fe + 3O_2
ightarrow2Fe_2O_3\).

Step2: Balance iron atoms

Now, since we have 4 iron atoms on the right - hand side (\(2Fe_2O_3\)), we put a 4 in front of \(Fe\) on the left - hand side. The balanced equation is \(4Fe+3O_2
ightarrow2Fe_2O_3\).

Answer:

4, 3, 2
