Torr
Atm
Pascal
What unit is equal to mmHg? Correct Answers Torr
What is the conversion of atm to mmHg? Correct Answers 1 atm= 760 mmHg
What is the conversion of atm to psi? Correct Answers 1 atm= 14.7 psi
What is Boyle's Law? Correct Answers P1V1= P2V2
Inverse relationship
Constants are temperature and amount of gas
Charles Law Correct Answers V1/T1=V2/T2 volume and temperature are linearly related
Pressure and amount of gas are constant
TEMPERATURES MUST BE IN KELVIN
Avogadro's Law Correct Answers V1/n1= V2/n2
pressure and temperature are constant
n is moles
Ideal Gas Law Correct Answers PV=nRT
P= pressure in atm
V= volume in L
n= moles
T= temperature in Kelvin
R= 0.08206
Volume of 1 mol of a gas at STP Correct Answers 22.4 Liters
STP Correct Answers Standard Temperature and Pressure
T= 0*C or 273 Kelvin
P= 1 atm
Density of a Gas Correct Answers density=PM/RT
density = pressure(Molar Mass)/0.08206(Temperature in K)
What makes the ideal gas ideal? Correct Answers The particles don't interact with each other Dalton's Law of Partial Pressures Correct Answers What are the three parts of Kinetic Molecular Theory? Correct Answers - the size of particles is negligibly small
- average kinetic energy is proportional to the temperature in kelvin
- the collision of one particle with another is completely elastic.
What is the kinetic energy formula? Correct Answers KE=0.5mv^2
Rate of Effusion Correct Answers rate of effusion/ rate of effusion = square root of the mass of gas b over mass of gas a
Work Correct Answers result of a force acting through a distance

Molar heat capacity Correct Answers the amount of heat needed to raise a mole of a substance by 1*C
Heat formula Correct Answers Enthalpy Correct Answers Heat= Energy + (pressure x Volume)
Hess's Law Correct Answers the change in enthalpy for a stepwise process is the sum of the enthalpy changes of the steps
Ionic Bond Correct Answers Metal and a nonmetal. Electrons are transfered
Covalent Bond Correct Answers two nonmetals share electrons
Metalic Bond Correct Answers two metals pool electrons
Octet Rule Correct Answers obtaining 8 electrons in the outermost shell of an element
