Answer : The correct option is, ![V_2O_5+5CaS\rightarrow 5CaO+V_2S_5](https://tex.z-dn.net/?f=V_2O_5%2B5CaS%5Crightarrow%205CaO%2BV_2S_5)
Explanation :
Balanced chemical equation : In the balanced chemical equation the number of individual elements present on the reactant side must be equal to the number of individual elements present on the product side.
The given balanced chemical reaction will be,
![V_2O_5+5CaS\rightarrow 5CaO+V_2S_5](https://tex.z-dn.net/?f=V_2O_5%2B5CaS%5Crightarrow%205CaO%2BV_2S_5)
There are 2 vanadium atoms present on reactant and product side. Therefore, vanadium is balanced.
There are 5 oxygen atoms present on reactant and product side. Therefore, oxygen is balanced.
There are 5 calcium atoms present on reactant and product side. Therefore, calcium is balanced.
There are 5 sulfur atoms present on reactant and product side. Therefore, sulfur is balanced.
