Greetings!
I believe the answer is true.
While precipitation does require a lot of energy, evaporation takes longer, and requires more energy from heat, whereas precipitation doesn't really require any.
Hope this helps you!

Answer:
Option C : Ag
Electronic configuration:
47Ag: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d9
The d-block elements are present in the middle of periodic table between s and p-block elements. d-block elements are also called Transition elements. Their valance electrons are reside in the d orbitals. They have more electropositive character than p-block elements but less than s- block elements.
C2H6 (g) + O2 (g). --> CO2(g)+H2O (g)
2C2H6 (g) + 7O2 (g). --> 4CO2(g)+6H2O (g)
(8.45 x 10^23)/(6.022x10^23) = 1.403 moles H2O
1.403 moles H2O x (4molCO2/6molH2O)= .935 moles CO2
.935 moles CO2 x (6.022 x10^23)= 5.63 x 10^23 molecules CO2
Polar bond.
A very common example is H2O.
The oxygen atom has an electronegativity value of about 3.5, while the hydrogen atoms have a value of about 2.2 (each).
Electronegativity describes how “greedy” atoms are with sharing electrons.
Since the oxygen atom has a greater value, it will be more “greedy” with the electrons.
