Hi Everyone
i have been having problems with my school calendar lately, and had to change one course to a grade 12 chemistry, i just attended the class for the first time friday, and it has been 2 weeks since it started. My teacher is going all out with no mercy and giving me an assignment that's due in 2 days, i am honestly screwed if i don't get this done, i have missed the first unit of the course, and this assignment is assoictated with it, i don't have a textbook yet, so i can't even try to learn it, i don't understand how she expects me to finish this, she said borrow a book from a classmate, and i don't know anyone...so this forum is my last resort, here it goes...
1) Draw an orbital diagram (line and arrow) for : Ca^+2
2) In chart form, generate a set of quantum #'s for the last 4 electrons in an atom having the electron configuartion ----> [Kr]5s^2,4d^1(subscript1), 4d^1(subscript2)
3) Draw and name the shape of the following molecules: a) CO3^-2 b) SF2
4) For the molecule PCl3 :
a) draw its lewis structure ( i think i can do this part)
b) Name the shape ( i think i got this also)
c) illistrate the polarity of each bond (lost here)
d) use the difference in electronegativites to determine the type of bond between P-Cl (lost also)
e) is the molecule POLAR or NONPOLAR? EXPLAIN (no clue)
5) What similarites and what diff would u expect in the molecular shape and intermolecular bonding of NH3 and BF3?
I would be very grateful if anyone with the knowledge can help me with these questions thank you very much
