Water Flashcards
1
Q
What is the chemical formula of water?
A
H2O
2
Q
What type of bonding is there within the molecule?
A
covalent
3
Q
Describe charges within the molecules
A
one delta negative hydrogen and one delta positive hydrogen
uneven distribution of charges so is polar but not charged
4
Q
What is hydrogen bonding?
A
-ve atoms and the +ve atoms are attracted to each other; as each water molecule has one of each, so therefore each H atom in each molecule bonds with another H atom of a different molecule.
5
Q
What are the properties of water?
A
- high specific heat capacity
- cohesion and surface tension
- solvent
- hydrolysis reactions
- upthrust
- solid = less dense than liquid
- transparent
- low viscosity
