oh nooes we gotta chem test on friday =O

we're being tested on lotsa info =( i hope i do well

we got:

covalent bonding, HONC1234
Lewis Dot Structures
the 5 categories of molecular geometry and their respective bond angles
the first 10 alkanes (methane (CH4), ethane (C2H6), propane (C3H8), etc.
saturated vs unsaturated hydrocarbons
Naming binary covalent compounds
isomers
polarity of bonds (electronegativity differences)
polarity of molecules, and symmetry
how water dissolves salts
the three types of bonds
alloys
the seven polyatomic ions to memorize: ammonium (NH4+), hydroxide (OH-), etc. (see the back of the pink PPT packet)
the seven diatomic elements (BrINClHOF)
review questions from past material

i hope we i do well on it :3

today, we did sum kool things

we bent a stream of water without touching it o.O

betcha cant do that xD

we messed with electrons

this past week we learned about lewis dot diagrams

thanksgiving is coming =D

Chemical Bonds

We learned about chemical bonds and all the cool different ways covalent bonds come together

we have a test this fri =O
i hope to do well on it :3
the stuff we did are really interesting!
studying light is really fun
also, the how ions come together in bonds is really interesting too
i never knew how sugar dissolved or why the sea was so salty but from this week's lessons, i finally understand!

do u like to mess round with sum weird machines that u dunno anything about?
well i do
this week, we got to mess with different types of light waves and their wavelengths
we got to look at different colors and i though that was cool since we only used color water :3

FIREEEE!!! and lotsa pretty colors xD

so this week we messed with FIRE
and lotsa different elements!
it made l0tsa different colors
i recommend, on ur free time, burn stuff and look at all the colors
