WebApr 5, 2024 · Iron has its bcc allotropy below 912° C (1,674° F) and from 1,394° C (2,541° F) up to its melting point of 1,538° C (2,800° F). Referred to as ferrite, iron in its bcc formation is also called alpha iron in the lower temperature range and delta iron in the higher temperature zone. WebIf we are going to identify the molecular mass of each reactant we have 223.2 g of Fe, 96g of O2 and 108g of H2O and to sum this we have 427.32 g of reactants that is the same as the molecular weight of the product. Thus when iron rust it increases weight because rust does not only contain iron but it also has an additional atom of Hydrogen and ...
