Chemistry of Snowflakes

Formation

Hydrogen-bonding and angle of water molecule allow the droplet to form a flake

Shape comes from the water molecule

Chemical Equation : 2H2 + O2= 2H2O

How do they get their shape?

-Starts as a dust grain in a cloud

-temperature changes the shape

How do the shapes differ?

Why are they white?

-The flakes actually reflect light

How do you make snow?

-most resorts use a snow gun or an airless snow gun
