How many moles of #Al# are needed to react completely with 1.2 mol #FeO# in the reaction #2Al + 3FeO -> 3Fe + Al_2O_3#?

Answer 1

0.8 moles

from the equation we can see, #2# mole #Al# is needed to react completely with #3# mole #FeO#
so, #3# moles of #FeO# needs #2# moles #Al# so, #1# mole #FeO# needs #2/3# moles #Al#
so, #1.2#mol #FeO# needs #(2xx1.2)/3#moles #Al#
#=0.8#moles #Al#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
