Unit 1: water and solutions Flashcards
specific heat
amount of energy needed to heat 1g of substance by 1 degree Celsius
cohesion
Hydrogen bonds of water with water
adhesion
hydrogen bonds of water w/polar substance
% solution equation
g/100 mL
cal equation
g*(change of temp)
mole
unit of measurement
Molarity equation
concentration x Mol Weight x Volume= mass
mol/L * g/mol * L = grams
molar mass equation and how to find it
g/mol –> it’s the atomic mass of the elements
solute
gets dissolved
solvent
does the dissolving
intramolecular
forces keeping atom together
intermolecular
forces between moleculars
hydrogen sphere
water surrounds molecuels
dissolved
water covers ions or polar molecules
ice has how many bonds
four
water has how many bonds
3
gas has how many bonds
0
water is most dense when?
right before freezing
water is like a
mosh pit, in the sense all the molecules are moving around
ice is like
ball room dancing, needs to have space for the four bonds
molar equation
mole/L
