polar covelent bonds

symmetrical (polar v non polar)

polar

charge different on both sides (polar V non polar)

non polar

same on both sides (polar v non polar)

polar

water

polar

if the difference in electronegativity is between .5-1.5 (polar V non polar)

polar covalent

the measurement of how hard and atom attracts electrons in a bond

electronegative

4 most electronegative elements

chlorine, nitrogen, oxygen, fluorine, hydrogen?

shape of water molecule

bent molecule

why do we use water to cool things off?

cohesion, adhesion, capillary action, surface tension, high specific heat, ice floats

very hard to change temp

high specific heat (cohesion)

human vs desert climate (open ended??)

hydrogen. deserts don’t have water vapor (nights) and no water vapor means cold. water in air makes it resist change

adhesion preserves cohesion when the tube is skinny

true

the tallest tree question

capillary action

why does chapstick stops lips from drying out

because the wax stops the water from coming out of the lips (non polar and hydrophobic)

ice floats t/f

false

hydrogen bond

the attraction between opposite dipoles in 2 different molecules (make them stick)

water has the ability to dissolve rocks

universal solvent

cohesion causes surface tension

true

polar and non polar stick together and ca cause emolsiving tensions

true

which of the following is false question

water is not polar because of the shape of the molecule
