One is Shrek element B while the other two are Dreck elements C and A
The balanced equation for FeS + O2 → SO2 + FeO is: 4FeS + 7O2 → 2SO2 + 2FeO
The balanced chemical equation for the reaction is: 2F2 + 2H2O -> 4HF + O2 This reaction produces hydrogen fluoride (HF) and oxygen (O2) from the combination of fluorine (F2) and water (H2O).
This is an oxidation reaction of N from -3 (in NH3) to +2 (in NO) oxidation value. 4 NH3 + 5 O2 --> 6 H2O + 4 NO
The combustion reaction of heptane is:C7H16 + 11 O2 = 7 CO2 + 8 H2O
The reaction HgO -> Hg + O2 is a decomposition reaction, where HgO breaks down into its constituent elements mercury (Hg) and oxygen gas (O2).
A chemical change, redox reaction: 2Fe(s) + O2(g) --> 2FeO(s)
Oxygen air. 2Fe + O2 -> 2FeO or 4Fe + 3O2 -> Fe2O3
Rust: 2Fe + O2 --> 2FeO Respiration: C6H12O6 + 6O2 --> 6CO2 + 6H2O
Fe2 + O2 --> 2FeO
A molecule which donates electron(s) to an other, is called a reductor orreducing atom / moleculeExample:2Fe --> 2Fe2+ + 4 e- reductor Fe4 e- + O2 --> 2O2- oxidator O2-------------------------------------------- +2Fe + O2 --> 2FeO redox reaction, the corrosion of Iron by Oxygen (forming rust)
There are two possible equations as iron is capable of forming two different oxides: O2 + 2Fe --> 2FeO 3O2 + 4Fe --> 2Fe2O3
The formula for iron (III) oxide is FeCl3, whether the formula is in a balanced equation or anywhere else where the formula is properly used.
Single replacement ex: 2K + 2HCl --> 2KCl + H2 Double replacement ex: Na2SO4 + 2CaCO3 --> Na2CO3 + CaSO4 Combustion ex: H2CO3 --> H2O + CO2 Synthesis ex: 2Fe + O2 --> 2FeO
2Fe(s) + O2(g) --> 2FeO(s)
Fe(s) + O2(g) --> FeO(s) You have to balance the equation so: 2Fe(s) + O2(g) --> 2FeO(s)
The balanced equation for FeS + O2 → SO2 + FeO is: 4FeS + 7O2 → 2SO2 + 2FeO
Hydrated Iron (III) oxide: 2Fe + 1.5O2 + xH2O -> Fe2O3·xH2O where x is the number of H2O molecules present.
