If gravity where much weaker, then the houses wouldnt need as much structural support, and then could be built much more taller as they wouldnt go through as much stress. and if gravity was stronger, buildings would need to be alot more structurally sound and wouldnt be able to maintain a tall structure as the force of gravity would be too much for them. hope i helped :3

Iron reacts with oxygen gas to produce iron (III) oxide. If there are 52 grams of
IRISSAK [1]

Mass of Fe₂O₃ : 74.26 g

Volume of O₂ at STP = 15.624 L

<h3>Further explanation</h3>

Reaction

4Fe (s) + 3O₂ (g) ==> 2Fe₂O₃ (s)

mol Fe :

Ar Fe = 56 g/mol

\tt \dfrac{52}{56}=0.93

mol Fe₂O₃ :

\tt \dfrac{2}{4}\times 0.93=0.465

mass Fe₂O₃ :

MW Fe₂O₃ : 159,69 g/mol

\tt 0.465\times 159,69=74.26~g

mol O₂ :

\tt \dfrac{3}{4}\times 0.93=0.6975

volume O₂ at STP(1 mol=22.4 L)

\tt 0.6975\times 22.4=15.624~L
