D because as the soda can starts to cool off the ice in turn begins to melt because the heat from the soda is being distributed on the ice and vice versa.
The two resonating structures of Carbon Monoxide are shown below.
The movement of electrons are shown by arrow.
Structure A: In structure a A the formal charges of Carbon and Oxygen are zero. As
Formal Charge is calculated as,
= # of valence electron - electrons in lone pairs + 1/2 bonding electrons electrons
For C: = 4 - 2 + 4/2
= 4- 4
=
0For O: = 6 - 4 + 4/2
= 6- 6
=
0Structure B:
Formal Charge on C: = 4 - 2 + 6/2
= 4- 5
=
-1Formal Charge on O: = 6 - 2 + 6/2
= 6 - 5
=
+1

Explanation:
What is the heat of reaction for the process NH4CI (s) ----> NH3 (g)+HCI (g)
The reaction taking place is a gas-phase acid-base reaction (both HCl and NH3 are volatile), that produces particulate NH4Cl as the sole product: HCl(g) + NH3(g) → NH4Cl(s). 1.
