AP Chem Unit 2 test
a molecule that has an uneven dispersion of charge
the interaction between the dissolving molecules and water molecules
what is being dissolved
what it is being dissolved in
conductivity comes from the presence of ions
-conducts electricity very efficiently
-all solute particles break apart into ions
-include soluble salts
conducts electricity only slightly
-a few solute particles create ions
does not conduct electricity
no solute particles create ions
includes soluble but nonionic compounds
HCl, H2SO4, HBr, HNO, HI, HClO4
measures atmospheric pressure
measures pressure of gas in a container
760 torr= 101,325 Pa= 101.325 kPa
V and T are ___ proportional. law?
directly, one goes up the other goes up.
P and V are ___ proportional. Law?
inversely. boyles law
V and n are ___ proportional. Law?
P and T are ___ proportional. law?
will the values be the same of two gases if they have the same volume and temp.- Kinetic energy
same because it depends on the temp
will the values be the same of two gases if they have the same volume and temp- Particle velocity
same because it doesn't depend on mass and all the other conditions are the same
will the values be the same of two gases if they have the same volume and temp- density
different D=m/v. since the mass is different it wont be the same
will the values be the same of two gases if they have the same volume and temp-pressure
same because it depends on temp and volume which are the same
ideal gas law
When gas is collected using water displacement, there is always a ____
mixture of gases
law of conservation of energy
energy can be converted but not created or destroyed
energy is produced in reaction, flows out of system (-)
energy is consumed by the reaction, flows into the system (+)
force acting over a distance
devise used to experimentally find the heat associated with a chemical reaction
heat capacity= ?
heat absorbed (J)/ increase in T (C or K)
Sp x m x ΔT
