Test 2 things to remember

1 atm =

760 mmHg (millimeters mercury) = 760 torr = 101.325 kPa

STP conditions

Standard temperature and pressure

pressure of 1 atm ( 760 torr ) and temperature of 273 kelvin ( 0 degrees celsius )

Temperature conversions

K = C + 273

C = K -273

Ek

kinetic energy

Ek = ?

1/2(m)(velocity² )

Rate of Effusion

Ratea/Rateb = sqrt(molarmassB/molarmassA)

Molarity

Moles of Solute / L of solution

Polyatomic Ions do not what

ionize

Covalent bonds are soluble in water?

no

Strong Acid

HBr , HCl, HClO4, HI, HNO3, H2SO4

do soluble ionic compounds 100% ionize

yes

Do weak acids, strong acids, weak bases, strong bases, and covalent compounds 100% ionize

weak acids, weak bases = <100% ionize

strong base, strong acids 100% ionize

covalent compounds dont ionize

total ionic shows all the ___

ions

draw a weak acid reaction using a __ arrow

double

How to recognize acids

typically start with H

How to recognize Bases

OH^-, ammonia ( NH3), or amines

Strong bases

Group 1 hydroxides, Ca(OH)2, Sr(OH)2, and Ba(OH)2

Dilution + equation

adding water to an existing solution, only volume of solution changes, moles of solute stay site same.

M1V1 = M2V2

a precipitate is when 2 aqueous solutions form a ___ product

solid

precipitate forms when the attractive forces in _______ are stronger than ____

an ionic compound are stronger than the forces between ions and water
