law of conservation of mass because the total mass on right hand side is equal to the left hand side therefore the mass is conserved
trinajhuri23:
sorry i didnt get it at all
see its very simple :
fe+H2o - Fe2O3 +H2
just sum up the mass of left hand side and compare it to the sum of right hand side
they would be equal

The law of conservation of mass states that there is no gain or loss in mass of a system when there is a reaction.According to law of conservation of mass
Sum of reactants = Sum of products
Reactant Side
Mass of Fe = 168g
Mass of H₂O = 72 g
Sum of reactants = 240g
Product Side
Mass of Fe₃O₄ = 232g
Mass of H₂ = 8g
Sum of products = 240g
Thus the law used in the formula is law of conservation of mass.
Sum of reactants = Sum of products
Reactant Side
Mass of Fe = 168g
Mass of H₂O = 72 g
Sum of reactants = 240g
Product Side
Mass of Fe₃O₄ = 232g
Mass of H₂ = 8g
Sum of products = 240g
Thus the law used in the formula is law of conservation of mass.
