Molecule of H2XeS is t shaped
Compound with unpaired electron is a free radical
Size of human egg compared to electron size, unit stuff
L not 2
Weakest O3 < O2 < N2 strongest
Work function = 373 kj/mol -> electricity
Midterm 2:

Fusion
1 mol + 3 mol -> 2 mol average V does down
Gas in a balloon properties
45.2g sample K + selenium -> 131.6g
Midterm 3:
● Reaction A+B -> C k[a][b] rate law must be first order when [A];<< [B];
● If rate law of multistep = 0 with respect to reactants that means that reactant collides with
any other reactants in any step of the mechanism – false
● Delta t of skillet with water vaporizing on contact
● Mechanism consistent with energy profile
● Order of reaction from energy profile
● Delta E fo combustion octane magnitude of 5000 enthalpy had magnitude of 4000
● Constant p form of NH3 from H2 + N2 volume goes down
● Solid CaCl2 added to ice at 0 degrees C Temp decreases initially
● Aqueous solution saturated with O2 + KI what happens to [O2]+[KI]
● Cube A is 5L -> 10 mol Cube B is 3L -> 10 mol which one greater entropy
● 2 tires same VT dif P which one larger Entropy
● Ground water Ion charge osmotic P changes how
● Vapor pressure only on T
● The maximum freezing point of a solution is determined by the solute's solubility (which
word should be changed?)
Midterm 4
