Im really struggling with this question and I have my chemistry exam next week.It says
The ore haemitite contains iron(III) oxide.Iron is extracted from this ore by reaction with carbon carbon.The products of this reaction are iron and carbon dioxide.
a)Finish the symbol equation(dont worry about this coz it is just balancing and I can do it)
b)A haematite ore contains 80% by mass of iron(III)oxide.
Calculate the maximum mass of iron that can be extracted from each tonne of this ore.
Show each step in your calculation as indicated below.
(1 tonne = 1000kg)
(relative atomic mass,A,.;Fe=56,O=16)
mass of iron (III)oxide in 1 tonne of haematite=..............kg
formula mass of iron(III)oxide =........................
mass of iron in 1 tonne of haematite=...................kg
plz help in anyway you can.
