Catalytic hydrogenation causes the oil to become saturated. So hydrogenated vegetable oil has fewer trans fatty acids and thereby less kinks. The greater the unsaturation (double bonds) the higher is the "kinks" in the fatty acid chains. Hydrogenated vegetable oil have higher melting point causing them to be solids at room temperature such as margarine. In the absence of double bonds (hydrogenated) the fatty acids pack tightly in a crystal lattice. Hydrogenated vegetable oil is likely to clog arteries.
The grams of Fe₂O₃ that are formed is 47.68 g
<u><em>calculation</em></u>
Step 1: write the equation for reaction
4 Fe +3O₂ → 2 Fe₂O₃
Step 2: find the moles of Fe
moles = mass÷ molar mass
= 33.4 g÷55.8 g/mol =0.5986 moles
Step 3 : use the mole ratio to determine the moles of Fe₂O₃
That is from equation above Fe:Fe₂O₃ is 4:2 therefore the moles of Fe₂O₃ is = 0.5986 moles x 2/4 =0.2993 moles
Step 4 : find the mass of Fe₂O₃
mass = mass x molar mass
The molar mass of Fe₂O₃ = (55.8 x 2 +(15.9 x3) = 159.3 g/mol
mass is therefore = 0.2993 moles x 159.3 g/mol =47.68 g
Glycine: Yes.
Dextrose: No.
Hope this helps! (:
