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.
Answer:
3
Explanation:
The first election shell can only hold 2 electrons, but the next one can hold up to 8
Iodate has a charge of -1, this means its chemical symbol
must be IO3(-1) while Lanthanum is La(+3). Therefore making the compound
La(IO3)3.
However sulfate has a chemical symbol of SO4(-2), it has
charge of -2, therefore the formula for lanthanum sulfate is:
<span>La2(SO4)<span>3</span></span>
Answer is: <span>decomposition.
Balanced chemical reaction: H</span>₂CO₃ → CO₂ + H₂O.
H₂CO₃ is carbonic acid.
CO₂ is carbon (IV) oxide or carbon dioxide.<span>
Chemical decomposition is the separation of
a single chemical compound (in this example </span>carbonic acid<span>) into
its two or more simpler compounds (in this example water and
carbon dioxide).</span>
<em>Answer:</em>
<em>Ello mate ! the answer is super simple it's option "A" Fe</em>
<em>Explanation:</em>
<em>Iron is a chemical element with symbol</em><em> "Fe"</em><em> and atomic number 26. It is a type of metal, that belongs to the first transition series and group 8 of the periodic table. It is by mass the most common element on Earth, forming much of Earth's outer and inner core.</em>
