Question:

Why the Blast Furnace can be used to extract iron from Fe2O3 but not Aluminium from Al2O3.?

Explain five the reasons that support statement above.

Answer:

Fiber is the indigestible carbohydrates found in unprocessed grains, fruits, vegetables, and some fiber-fortified foodsWhen you eat something with fiber in it, you consume a few fewer calories because your body cannot absorb fiberFoods with fiber also tend to have lower calorie counts, which can help trim your middle, so to speakFiber makes you feel fuller so you can eat less without feeling hungryWhen trying to get more fiber, leave the skins on fruits such as apples, pears, peaches, grapes, etcto get the most fiber and benefitsThe most fiber-rich (and tasty) foods include: Apples (3-8g per serving, depending on size) Pears (4-5g) Kiwi (3g) Blueberries (5g) Raspberries (8g) Strawberries (3-5g) Rye (3-6g) Whole wheat (Wheaties, whole wheat tortillas, etc)(5-8g) Oatmeal (5-8g) Amaranth (5g) Brown rice (2g) Air-popped popcorn (5g) Bran (Up to 14g) Carrots (2g) Baked potato WITH skin (8g) Brocolli (2-4g) Green beans (3-5g) Spinach (3-5g) Bruessel sprouts (3g) Beans (5-8g) Peas (4g)
Fibre is found in foods like wheat, for instance shredded wheat cereal has a lot of fibre in it.Hope it helps
Fiber helps move food thru your system faster.less time for fat and carbs to be absorbed out of itYes, it worksBut not miraculousBut it does help, no doubt there for me.
Fiber is used to bulk up your stoolsNever heard of it for slimming the waist downFiber is found in fresh fruits, pear, apples etcYou can also find it in nuts as well as other foods.
Iron is liberated from it's oxide in a blast furnace by carbon monoxide, the carbon monoxide simply removes oxygen from the iron oxide to become carbon dioxide leaving elemental ironThe same process will not work with aluminum oxide because aluminum has a much higher electropositive potential than ironWhat this means in simple language is that aluminum gives up more energy than iron when it forms it's oxide and it takes more energy to remove oxygen from aluminum oxides than it does from iron oxides.
