What type of bonds do water have within its molecule?
polar
what kind of molecular bonds are symmetrical?
polar bonds
what type of molecular bonds are asymmetrical?
non polar bonds
Which element receives the partial positive on an H2O molecule?
Hydrogen
Which element receives a partial negative charge in a H2O molecule?
Oxygen
What type of bond is formed between two water molecules?
hydrogen bond
In order for a hydrogen bond to be made _, , or have to be present
N, O, or F
What are the special properties of water?
Cohesion/adhesion, solvent, states of matter, high specific heat, high temperature of vaporization
Cohesion/adhesion, solvent, states of matter, high specific heat, high temperature of vaporization are all qualities of what molecule?
Water
What is the difference between cohesion and adhesion?
Cohesion is sticking to itself and adhesion is adding to something else
What is more dense liquid or solid water?
Liquid
What is specific heat?
The amount of energy it takes to heat up 1g by one degree Celsius
Why does it take so much energy to vaporize water?
Because it takes a lot of energy to break the hydrogen bonds
