H2(g)+V2O5(s)→V2O3(s)+H2O(l)
Let the coefficients for the given reaction be as follows:
AH2(g)+BV2O5(s)→CV2O3(s)+DH2O(l)
What will be the equations for the number of atoms each element, so that each is balanced?
A = D, B = C, 5B = 3C + D
Equating the number of atoms for each element on the two sides of the equation, we get:
A = D, B = C and 5B = 3C + D.
