Solution

The correct option is D 5

A chemical equation should be balanced to maintain the law of conservation of mass. That mean, on each side of the equation, equal number of atoms should be present. For the given reaction: Fe+H2OFe3O4+H2

Number of Fe atoms on the LHS=1

Number of Fe atoms on the RHS=3

So we multiply Fe in LHS with 3​

Now, the number of O atoms on LHS=1

Number of O atoms on the RHS=4

So, we multiply H2O with 4​

Finally, number of atoms of H on LHS=8

Number of H atoms on the RHS=2

So, we multiply H2 by 4 ​

The final equation is 3Fe+4H2OFe3O4+4H2

Hence, b+c=4+1=5
