Water

Question 1

Describe the shape of water

Answer 1

V-shaped 2 h and 1o connected with polar covalent bonds
Oxygen is more electronegative so the e of covalent bond spend more time there
V-shaped makesit polar molecule with oxygen slightly neg and hydrogen slightly POS

Question 2

How are water muleules held together

Answer 2

Hydrogen bonds, accounts for the properties of water

Question 3

Emergent property

Answer 3

A characteristic only when apart of larger group

Question 4

What are 4 emergent properties of h20?

Answer 4

Cohensionlddhesion/surface tension
High specific Heat
Frozen water
Universal solvent

Question 5

Explain cohesion and adhesion

Answer 5

Cohesion = b/n H 20 molecules
Adhesion = H 20 and other
Plants transport h20frm roots to leaves usury xylem via capillary action: cohesion and adhesion to xylem cell walls

Question 6

Explain surface tension in relation to emergent

Answer 6

High be of h-bonds water coheres to itself

Question 7

High specific Heat

Answer 7

Most energy needed to break H-bonds than any other intermolecular bond
Refers to amount of heat absorbed/lost for one g change

Question 8

How might high specific heat be helpful?

Answer 8

Bodies of H2O can regulate temp without changing water tump too much
Heat Bank

Question 9

Temp us Heat

Answer 9

Temp: measure of kinetic enemy
Heat: kinetic energy

Question 10

What is evaporation how does it relate to evaporate cooling

Answer 10

It molecules more fast enough they can break attraction and break off
Evaporative cooling; stabilize temp the hottest leave

Question 11

Universal solvent

Answer 11

Great at breaking ionic bonds since attraction is nice it will form hydration shell
