If 2.32 moles of iron react with excess oxygen gas, how many moles of Fe2O3 can be produced?
bearhunter [10]

Moles Fe₂O₃ produced : 1.16 moles

<h3>Further explanation</h3>

Given

2.32 moles of iron

Required

moles of Fe2O3

Solution

The reaction coefficient in a chemical equation shows the mole ratio of the reacting compounds (reactants and products)

Reaction

4 Fe + 3 O₂ ⇒  2 Fe₂O₃

From the equation, mol ratio Fe : mol Fe₂O₃ = 4 : 2, so mol Fe₂O₃ :

= 2/4 x mol Fe

= 2/4 x 2.32

= 1.16 moles

If the gas inside the flask is cooled so that its pressure is reduced from 797.3 torr to a value of 715.7 torr what will be the
nadezda [96]
The differential pressure is
797.9 - 715.7 = 82.2 torr = 138815.25 Pa
The height of the mercury in the open-end arm is calculated using
ΔP = ρgh
The density of mercury is 13560 kg/m3
The height of the mercury is
138815.25 Pa = 13560 kg/m3 (9.81 m/s2) h
h = 1.04 m
