If you have iron(II) oxide(s) + oxygen(g) ---> Iron(III) oxide(s), Would the answer be FeO3 + O2 ---> FeO3 for a skeleton equation?
not quite.
FeO + O2 ==> Fe2O3
For iron(II) oxide. you're told Fe is +2 and you know O is -2; therefore, the formula must be FeO
For iron(III) oxide, iron is +3 and O is -2; therefore the formula is Fe2O3.
To determine the correct skeleton equation for the given reaction, we need to balance the equation by ensuring the number of atoms of each element is equal on both sides of the equation.
First, let's write the chemical formulas of the reactants and products:
Reactants: iron(II) oxide (FeO) and oxygen (O₂)
Product: iron(III) oxide (Fe₂O₃)
Now, let's balance the equation step by step:
1. Start by balancing the least common element, which in this case is oxygen (O).
On the reactant side, we have one oxygen atom from FeO and two oxygen atoms from O₂, giving us a total of three oxygen atoms.
On the product side, we have three oxygen atoms from Fe₂O₃.
To balance the oxygen atoms, we can multiply FeO by 3:
3FeO + O₂ ---> Fe₂O₃
2. Next, check if the iron (Fe) atoms are balanced.
On the reactant side, we have three Fe atoms from 3FeO.
On the product side, we also have three Fe atoms from Fe₂O₃.
Since the iron atoms are already balanced, we don't need to make any changes.
Therefore, the correctly balanced skeleton equation for the given reaction is:
3FeO + O₂ ---> Fe₂O₃
