The given balanced reaction is,

The stoichiometric coefficients of each element or compound represents the number of moles of that element or compound required for the complete reaction to take place.
The mole ratios of different products and reactants will be:



So the mole ratio comparing iron (Fe) and oxygen gas (
) is
4 : 3
Because it is a covalent bond meaning that they share the electrons to achieve full valence.
I believe it is B. I’m sorry if i’m wrong. Tell me if i’m wrong or right!
This answer would be heat capacity
Answer:
10
