First step in answering the question is to establish a balanced chemical reaction equation. More specifically, a combustion chemical equation.
CH4 + 2O2 ---> CO2 + 2H20
Then using dimension analysis:
Because the coldness in the ice cream and the suns gamma rays are hitting the ice cream and then it will start to melt. and that is why ice cream melts.

Answer:
Lone pairs and bonding pairs
Explanation:
The electron domain around the central atom includes
- All lone pairs on the central atom
- All bonding pairs between the central atom and the atoms directly attached to it
Double and triple bonds count as single domains.
Thus, the nitrite ion has three electron domains:
- A lone pair
- An N-O single bond
- An N-O double bond
