<span>he balanced equation for the reaction is
4Fe + 3O</span>₂ ---> 2Fe₂O₃<span>
stoichiometry of O</span>₂ to Fe₂O₃ is 3:2
number of O₂ moles used up - mass present / molar mass of O₂
number of O₂ moles = 63.98 g / 32 g/mol = 1.999 mol
if 3 mol of O₂ forms 2 mol of Fe₂O₃
then 1.999 mol of O₂ forms - 2/3 x 1.999 mol = 1.333 mol
answer is A) 1.333 mol of Fe₂O₃ are formed
Answer:
circulatory system

The <em>Carboxylic Groups </em>are encircled in Yellow Sphere.
The <em>Amino Groups</em> are encircled in Orange Spheres.
The <em>Alpha carbons</em> are encircled in Pink spheres.
The <em>water molecule</em> evolved is in corresponding colors of its parent molecules.
The<em> peptide bond</em> formed is colored by Green color.
Nonmetals which are located in the second row form pi bonds
more easily than the elements situated in the third row and below. Actually there
are no compounds or molecules known that forms covalent bonds to the noble gas
Ne and Ar. Hence the other second row element which is Carbon, is the element that
forms
pi bonds most readily.
