The reaction is
FeO + Fe3O4 + 1/2 O2---> 2Fe2O3
Thus as shown in the balanced equation two moles of Fe2O3 are formed when 0.5 moles of O2 reacted with mixture of FeO and Fe3O4
moles of Fe2O3 = MAss / Molar mass = 4.141 / 159.69 = 0.0259 moles
So moles of O2 needed = 0.5 X 0.0259 = 0.01295
Mass of O2 = moles X molar mass = 0.01295 X 32 = 0.4144 grams
Answer:
Hydrogen Bond is the force that exists when H is directly connected to F, O, or N. HCl and HI cannot form hydrogen bonds between them. CH3OH and NH3 can form hydrogen bonds between them. CH4 and H2O cannot form hydrogen bonds between them.
Explanation:
Energy absorbed from
changing the phase of a substance from the liquid phase to gas phase can be
calculated by using the specific latent heat of vaporization. Calculation are
as follows:
<span> Energy = 1.35 mol CCl4 ( 153.81 g / 1 mol ) x 197.8 J/g </span>
<span>Energy = 41071.88 J</span>
