Answer:
80.13g of SO2
Explanation:
4FeS2 + 11O2 —> 2Fe2O3 + 8SO2
Molar Mass of FeS2 = 55.8 + (2x32) = 119.8g/mol
Mass of FeS2 from the balanced equation = 4 x 119.8 = 479.2
Molar Mass of SO2 = 32 + (16x2) = 32 + 32 = 64g/mol
Mass of SO2 from the balanced equation = 8 x 64 = 512g
From the equation,
479.2g of FeS2 produced 512g of SO2.
Therefore, 75g of FeS2 will produce = (75 x 512)/479.2 = 80.13g of SO2
The molecule expand to relieve steric strain before undergoing torsion to a non-planar structure in order to have several resonating structures.
<h3>What is a molecule?</h3>
It should be noted that a molecule simply mean the group of atoms that are bonded together that represents the smallest fundamental unit if the chemical compound.
It should be noted that structures containing fused benzene rings have extensive conjugation. Due to this, they can undergo resonance.
This is vital in decreasing the overall energy of the molecule and helps increase its stability. When there's a change in torsion angle to relieve the steric strain, the molecule won't be planar, hence, the energy will increase and the stability will reduce.

Explanation:
Move fast and are far apart is the correct answer
Answer:
The answer to your question is X = 0.072
Explanation:
Data
X I₂ = ?
mass of I₂ = 55.6 g
mass of hexane = 245 g
Formula
X I₂ = (moles of Iodine) / (moles of iodine + moles of hexane)
Process
1.- Convert the mass of reactants to moles
atomic mass of I₂ = 2 x 127 = 254g
atomic mass of hexane = (12 x 6) + (14 x 1) = 86 g
254 g ---------------- 1 mol
55.6 g------------- x
x = (55.6 x 1)/254
x = 0.22 moles of I₂
86 g ------------- 1 mol
245 g ------------- x
x = (245 x 1)/86
x = 2.84 moles
2.- Calculate the mole fraction of I₂
X = 0.22 / (0.22 + 2.84)
X = 0.22 / 3.07
X = 0.072
