Answer:
It is a typical fires that started out of a lightning strike, or people carelessly starting it, or accidentally, or even arson, that went un-noticed and got out of hand.
The grams of FeO that would be needed to make 234.2 grams of Fe is
1204.42 grams
<u><em> calculation</em></u>
4 FeO → Fe₃O₄ +Fe
Step 1: find the moles of fe
moles = mass /molar mass
from periodic table the molar mass of Fe = 56 g/mol
moles = 234.2 g/56 g/mol = 4.182 moles
Step 2: use the mole ratio to determine the moles of FeO
FeO: Fe is 4:1 therefore the moles of FeO =4.182 moles x4 =16.728 moles
Step 3: find the mass of FeO
mass = moles x molar mass
The molar mass of FeO = 56 +16 = 72 g /mol
mass = 16.728 moles x 72 g/mol= 1204.42 grams
