Answer:- D. 1.8 moles of Fe and
.
Solution:- The balanced equation is:

let's first figure out the limiting reactant using the given moles and mol ratio:

= 5.4 mol CO
From calculations, 5.4 moles of CO are required to react completely with 1.8 moles of Iron(III)oxide but only 2.7 moles of CO are available. It means CO is limiting reactant.
Products moles depends on limiting reactant. Let's calculate the moles of each reactant formed for given 2.7 moles of CO.

= 1.8 mol Fe

= 
So, the correct choice is D. 1.8 moles of Fe and
are formed.
A substance that has no specific volume changes to a substance that has a specific volume.
Answer:
Motion is defined as a change of position. How we perceive motion depends on our frame of reference. Frame of reference refers to something that is not moving with respect to an observer that can be used to detect motion.
