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 for 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.
