Honors Chemistry Spring Final Review Question 16 f-j



Welcome friends,

WHO'S READY FOR SOME REVIEW ANSWERS?!?!?! WHOOP WHOOP

16.

F) HNO3 + KOH --> KNO3 + H2O
     (aq)        (aq)         (aq)       (l)
H + + NO3- + K+ + OH- --> K+ + NO3-+ H2O
H+ + OH-  --> H2O 
NO3-  and  K+ are spectator ions



G) 2AlPO4--> Al2O3 + P2O5      (Use oxidation numbers to find P2O5) (Put a triangle over the arrow because heat is used)



H) Ag + Al(NO3) --> No reaction (Ag is below Al on the activity series, so it can not replace it in the reaction)



I) Ba(ClO3)2 --> BaCl2 + 3O2  (MgO2 is a catalyst, so you write it over the arrow)



J) MgSO4 + CuNO3 --> Mg(NO3)2+ Cu2SO4 

    (aq)           (aq)              (aq)              (aq)
No Reaction- a solid needs to be yielded in a double replacement.


You're welcome.

    Wonderful post, Brandt. But I think you made an error. There aren't two NO3- ions in that equation. But other than that, looks good! Love the enthusiasm!

      That's strange, I don't see an extra NO3-... Thanks for keeping a watchful eye anyways!

    Brandt, once again you have surpassed my expectations with your abundant supply of enthusiasm. As far as I can see you do not have any mistakes so keep up the wonderful work!

    Brandt, excellent work! However, I'm not sure if you are aware that your arrows have turned into mailboxes. At least on my computer. I like the way you noted why the reaction didn't happen if it didn't.

      That is really strange... On my computer, it's just two dashes and a greater than sign. It must be a blogger thing, because on yours, the arrows come up as a's with an accents over them.
