1. Mini exam, next week in discussion sec
When atoms form bonds as energy release because
the resultant has a lower energy level; but at some
circumstance energy might be absorbed.
- bonding explains chemical activities and reaction
Q: As molar mass of a gas increases, its pressure should decrease (assume everything
else is constant)
- decrease, because the frequency that hit the wall is slower as the molecules get heavy
Ideal Gas Law: E(QV) of State - related differ.(Pressure
Q: in which case is Ed the most appro.?
1. Nacl 2. CaBr2 3. Ali3
3, b/c polorization, creates more covalent chara.
- atoms of similar electronegativities share electrons and form molecules- this is what
- chara. bonds accordi
First Law: Thermochemistry
Thermodynamics: First Law
Thermodynamics: Study and measure of the nature of heat and
energy and its transformations
Energy flow is key in science; understanding it will help us to
understand WHY things occur.
