Chapter 10 Flashcards
The molicules in a sample solid of SO2 are attached to each other by a combination of what forces?
London forces and dipole-dipole interactions
What are the three types of atomic solids
1.metallic solids
2.network solids
3.group 8A solids
Difference between amorphous solids and crystalline solids
Crystalline solids have a lattice and are arranged regularly; amorphous solids are not
^Hvap corresponds to what
Boiling/condensation and endothermic reactions
^Hfus corresponds to what
Melting/freezing and exothermique reactions
Important formulas for heating and cooling curves
• q = m•^Hf or ^Hvap
• q=ms^T
What is the value of R
8.314 J/molK
ln(p1/p2)=^Hvap/R((T1-T2)/(T1T2))
What is this equation?
The Calais -Clapetton equation
What is the relationship between vaper pressure and temperature
Nonlinear and logoramithic
Heat of vaporization
The energy required to vaporize a liquid at 1 atm
Simplest unit cell
Simple cubic - an atom at every corner - least dense
Body centered unit cell
When an atom sits in the middle of a unit cell - middling density
Face centered unit cell
An atom on each face of the cube- most dense
How much does the atoms in the corner of a unit cell contribue to the density
1/8th
How much do the atoms on the face of a unit cell contribue to the density
1/2
