When iron (Fe) reacts with molecular oxygen (O2), a new compound is formed. This compound is the Fe2O3 found in rust. 4 Fe + 3 O2 → 2 Fe2O3

If 112 g of Fe combines with 48 g of O2, how much Fe2O3 is formed?
A. 48 g Fe2O3
B. 112 g Fe2O3
C. 88 g Fe2O3
D. 160 g Fe2O3

I will also mark brainiest for the correct answer!

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
