The composition of magnetic ore is :
In the production of iron, intermediate are FeO, Fe2O3, and Fe3O4, which are oxide . If true enter 1 else 0.
A mixture of FeO and Fe3O4 when heated in air to a constant mass gains 5% by mass. calculate the composition of the mixture?
A mixture of FeO and Fe3O4 when heated in air to a constant weight gains 5% of its weight. Find the composition of its initial mixture.
