Because of the crystal structure of the ice, ice has lower density than liquid water. So the volume of the ice of same mass is greater than water. When melting, the volume will decrease.
OC. (Third one) is balanced
Explanation:
neon has 8valence electrons

nitrogen has 5 valence electrons
oxygen has 6 valence electrons
so neon has the most valence elctrons
