also salt water could be separated by evaporation right? Distillation was for the methane one
No, salt water was distillation… the Ca vs CaO was the straight line graph (think law of def composition)
salt water was evaporation.
*methanol but yes
Ca vs CaO was the linear graph
I got salt water Was evap???and for CaO I got the straight line , CO2 I got H1=H2+H3
I got the same answers as you
Anyone remember any other questions?
does anyone remember the exact isotope question
The heat of fusion problem… Did you guys get the negative of the given number?
For one of the questions it asked the answers were all like C( ) H ( ) O ( ) I remember putting the answer with C8 (It was the problem where they gave you half of the reaction…)
Isotope went like… Protons= 13 Electrons= 13 Neutrons =14 what was the possible isotope?
I got twice the negative I think…
I think I got negative of the number doubled, but now that I think about it, I’m pretty sure i was wrong
that one was the formula of aspirin
It was CH8
Oh I put that it had to be the only choice with protons being 13 … (there was only one)
it was c9h8o4
AA) What did you guys got for the question of (delta H equation) the formation of carbon dioxide.
BB) The half reaction referring to the Na (Sodium)
- Na(s) ----> Na(aq) + e (couldn’t remember exactly)
it had to have 13 protons…all isotopes of an element have the same number of protons
