Consider a 5.430-g mixture of FeO and Fe3O4. You react this mixture with excess of oxygen to form 5.779g Fe2O3. Calculate the percent by mass of FeO in the original mixture.
cdotter said:You can start by writing a balanced chemical equation for the reaction.
The total mass of the mixture is 5.430 grams.
The amount of FeO present in the mixture can be determined by subtracting the mass of Fe3O from the total mass. Without knowing the amount of Fe3O present, this question cannot be accurately answered.
The ratio of FeO to Fe3O in the mixture can be calculated by dividing the mass of FeO by the mass of Fe3O. Without knowing the individual masses, this question cannot be accurately answered.
The chemical formula of the mixture is a combination of FeO and Fe3O, but without knowing the individual amounts present, a specific formula cannot be determined.
One method to separate FeO and Fe3O in the mixture is by using a magnet. Since Fe3O is magnetic and FeO is not, the magnet can be used to attract and remove the Fe3O. Other methods such as filtration or chemical reactions can also be used depending on the specific properties of the mixture.
