Answer:
Explanation:
Dear Student,
When iron is strongly heated with steam (H2O) a mixed oxide (Fe3O4) of Iron is formed as the following equation.
3Fe (s) + 4H2O (g) → Fe3O4 (s) + 4H2 (g)
A
molecular weight (M) of Fe3O4 (A) = 232 g/mol (Approximately)
M/4 = 232/4 = 58
Hope this information will clear your doubts about topic.
