I believe it’s evaporation?
Explanation:
n=given mass ÷molar mass
make given mass become the subject of the formula by
multiplying the molar mass on both sides of the equation.
n=0.473mol
given mass=??
molar mass=48
therefore,given mass=n×molar mass
=0.473×48
=22.704grams
mass in grams is 22.704grams
Fe + O2 → Fe2O3
After balancing the eq.
4Fe + 3O2 → 2Fe2O3
Hope this will help u mate :)
The attraction of an
ion leads to the formation of an ionic bond with 
<h3>What is an ionic bond?</h3>
Ionic bond, also called an electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound.
Since the question asking among all these options:
(a) The attraction of a noble gas
(b) The attraction of a
ion
(c) The attraction of a group 1 element
(d) The attraction of a
ion
An ionic bond can be formed after two or more atoms lose or gain electrons to form an ion. Ionic bonds occur between metals, losing electrons, and nonmetals, gaining electrons.
Hence, option D is correct.
