why mass need to be conserved in extraction of iron

Iron Conservation Part II Experimental Variable andA conserved artifact of iron from a marine site remains a piece of metal, just as susceptible, and in fact more susceptible, to continued corrosion as any other piece of iron. Proper conservation does not ensure that an object will be preserved in perpetuity.mass conservation IUMass conservation can be used in chemical calculations. For example iron rust by combining with oxygen to form rust (iron oxide). Suppose 100 g of iron metal rusts. We weigh the rust and find that the rust has a mass of 143 g.Extracting iron Redox, extraction of iron and transitionExtracting iron The blast furnace.
