Step-by-step explanation:
Here, we want to balance the given chemical equation
We can start by balancing the oxygen atoms
We have 7 on the left and 2 on the right
To make a balance, we place 7 before the molecular oxygen on the left and 2 on the given oxide
That means we would be having 4 Rh on the left
To balance the Rh, we have to place 4 on the left side
Thus, we have the balanced equation as:
![4Rh+7O_2\text{ }\rightarrow2Rh_2O_7](https://img.qammunity.org/2023/formulas/chemistry/college/jtfo1l0wf23r2y5ta7n5k3v7amxf7ef181.png)
