What is the balanced equation for FeS2 O2?
Fe2O3 +
FeS2 + O2→ Fe2O3 + SO2.
How do you calculate equivalent weight of iron?
Iron (atomic weight 55.845) has an equivalent weight of 27.9225 in ferrous compounds (valence 2) and 18.615 in ferric compounds (valence 3). The weight proportion in which elements or radicals combine to form compounds can be determined from their equivalent weights.
What type of reaction is FeS2 o2 Fe2O3?
This is a combustion reaction and generates iron (III) oxides.
What is the oxidation number of iron in FeS2?
In FeS2, iron is in +2 state. FeS2 contains the S2(2-) ion, which is analogous to the peroxide ion, O2(2-). The oxidation state of sulphur is -1 in FeS2, just as oxygen is in peroxides like H2O2 and BaO2.
How do you find the equivalent weight of oxidant and reductant?
Equivalent weight of a substance (oxidant or reductant) is equal to molecular weight divided by number of electrons lost or gained by one molecule of the substance in a redox reaction.
What type of reaction is FeS2 O2 Fe2O3?
What is the EQW of Fe in FeS2?
E.W= M.W of oxidant or reductant/ no of electrons lost or gained. Reason: Fe in FeS2 is in +2 state changing to +3 state of Fe2O3. In redox reactions Eq.wt of oxidant or reductant is determined based on the no of
What is the n factor of FeS2 in this reaction?
Fe from +2 to +3 and S from -1 to +4 therefore n factor of FeS2 is 11. It is a redox reaction.Number of electrons gained =Number of electrons lost. Each O atom takes 2 electrons for reduction. Therefore for 1 O2 molecule 4 electrons are absorbed for reduction.
How many electrons does Fe2O3 lose in FeS2?
Fe in FeS2 is in +2 state changing to +3 state of Fe2O3. So losing 1 electron. Out of two S atoms one is in — 2 state and another in zero state. But both are changing to +4 state of SO2. That means together they are losing 10 electrons (6 and 4 respectively). Therefore on the whole FeS2 is losing 11 electrons.
