Chemistry 11-7-17 Binary Molecular Formulas

CHEMISTRY: Do you feel like you have letter and numbers swimming in your eyes? This is one of those times that paying attention to details is super, super important! Here’s the lecture from today on writing formulas and names for binary molecular compounds. Part of it’s really similar to what you learned to do last week for ionic compounds, but another part is totally different. Details!!

Make sure you keep everything straight. Do something that will organize all the information for you, so you won’t get confused. Also, don’t forget the lists you have to memorize – it’s getting larger and larger!! And practice, practice, practice!!!

Need extra practice? Help session tomorrow morning, 7:20ish A.M.

  1. This week in chemistry I rate myself a 4/5 this week. I had a rough time studying for the quiz on Wednesday. I feel like i’m understanding the stuff you taught this week

  2. This week I rate myself a 4/5. I did very well on the polyatomic ion quiz this week, and the material all seems to make sense to me, and I understand it.

  3. I rate myself a 4/5 this week. I did really well on my polyatomic quiz and already studying my acids for the pre test! I went to the chemistry help session this week and that helped me a TON.

  4. I struggled with the quiz we had on chemical formulas and names quiz we had this Wednesday and I am looking over the sheet that is on the website and am studying the ones I think I missed and studying the entire sheet to be prepared for the pre-test we will have on the 14.

  5. I would rate myself a 3/5 this week because I learned I need to study for the memorization quiz diffently. Also I think I am understanding what we are studying and learning how to apply it.

  6. This week in Chemistry I rate myself a 4.5/5. I really like this chapter we’re learning and I seriously love writing chemical formulas and doing the practices! I’m also super happy with my polyatomic ions quiz grade! Overall, it was a great week in Chemistry!

  7. This week i rate myself a 4/5. i did really well on the polyatomic ions quiz. i also did really well staying on top of my work and my notes. i really understand what we are learning.

  8. I rate this week a solid 5/5. This information is making sense so far and the constant practice is only making me better. I didn’t miss anything on the polyatomic ions quiz, which makes me pleased. To perfect my formula writing skills, more practice will be needed. I’m sure I’ll get plenty these next few weeks!

  9. I would rate myself a 3/5 because im doing well on the formulas but not so well on the polyatomic ions. I need to keep studying and working hard.

  10. This week I would rate myself a 3/5. Even though I did well on my polyatomic ions quiz I still need to be memorizing new information every day for the test. Also I need to continue working on the formulas

  11. I would rate myself a 4/5 for this week. I did very well on the online exercises we did in class, but I did not do to well on the quiz and I need to work on memorizing polyotomic ions.

  12. i rate myef a 3/5 this week. i was able to complete all my homework but i still haven’t found a good way to study that’s working for me.

  13. This week I rate myself a 5/5. I really like this chapter we’re learning and I like writing chemical formulas and doing the practices! I’m also super happy with my polyatomic ions quiz grade! To perfect my formula writing skills, more practice will be needed.

  14. I would rate myself a 4/5 this week. I did good on the polyatomic ions quiz and I’m understanding how to write the formulas.

  15. Another week, another series of days spent juggling keeping up in chemistry, studying my lines for the play, and keeping up with all my other classes. I’ve done wildly well this week though it’s been a busy one. I’d give myself a 5 out of 5 this week for keeping up and not stressing over tests and quizzes. However, I feel that these chemical formulas are going to nip me in the bud sooner or later.

  16. I rate myself a 5/5 this week I think I did a good job memorizing the ions and all the stuff for the pre test and I’ve taken good notes all week

  17. I rate myself a 2/5 for this week. I did terrible on my memorization and still didn’t understand. Need to find a new method to study. Am having lots of trouble with the numbers and non direct element abbreviations

  18. I would say this chapter is my favorite! I actually really enjoy writing formulas, and I was well prepared for the polyatomic quiz! The only thing i’m really struggling on is the prefixes, so that’s my main focus point to prepare for the pre-test next week. Overall I would rate myself a 4/5 for the week.

  19. This week in chemistry I would rate myself a 2/5 i did not do my best on polyatomic ion quizzes. Hopefully will do better on pre test tuesday.

  20. I rate myself 4/5 this week. I feel like I’m really starting to understand the notes and formulas. I just need to make sure I memorize everything for the test

  21. I would rate myself a 4/5 this week I did well on both polyatomic ion quizzes and feel like I did well on taking notes.

  22. I would rate myself a 4/5 this week. I feel like I triumphed at taking notes and completing my homework; however, I feel like I could have studied more for the polyatomic ions quiz.

  23. I would rate myself I 3/5 this week. I did well on polyatomic ion quizzes. And I understand what we’ve been learning in class.

  24. I would rate myself a 4/5 this week i think I get everything! I’m usually ok at memorizing things. I did good on the quiz i think!

  25. This week I rate myself a 4/5 because I am memorized the poly atomic ions and did well on the quiz. Also chemical formulas are becoming easier to me.

  26. This week I give myself a 2/5. I could have studied better for the quizzes and taken better notes, but I still passed both of them and I understand the new chapter so far. However, I found a new method for memorization that I will definitely utilize in the future!

  27. I rate myself a 3/5 this week. I could have studied better for the polyatomic ions quizzes, but I did well on both. At the beginning of the week I didn’t understand what we were doing, however, after practicing, I feel like I understand better, but not completely. Also I should have gone to the help session. I will definitely need to practice more and watch the vodcasts. But I finally remembered the web post!

  28. I would rate myself a 3/5 this week. I did well on the chemical review games and made a 100 and two 90s on them but i need to keep memorizing. I did not do too good on the polyatomic ions quizzes but i am going to study this weekend and memorize them.

  35. This week I would rate myself a 4/5. I did very well on the polyatomic ion quiz and kept up with my homework and studying. I need to remember to keep studying what I need to memorize however. I also am understanding the formulas and how to write them pretty well. Looking forward to another great week of Chemistry!

  36. I rate myself a 4/5 this week because I made 100s on all my polyatomic ion quizzes and what we learned, I caught along with it when I got back to school from being sick!

  37. this week i rate myself a 4/5. i did well on the two polyatomic ion quizzes. i’m a little worried about all of the things we have to memorize, but if i can focus i’ll get it done.

  38. I rate myself a 3/5 for this week. I didn’t do as well as I should have on the polyatomic ions quizzes. I did good paying attention this week and took good notes.

  39. This week I rate myself a 3/5 I found that memorizing the ions was way more difficult than I thought I can do we’ll recognizeing them but I have trouble when it comes to memorizing them

  40. This week in chemistry I rate myself a 3/5. I did good on my polyatomic ions quizzes, but I have not been memorizing everything I need to know for the test. This weekend I’m going to start memorizing the things I need to know>

  41. I would rate myself a 4/5 this week because I did well on both polyatomic ion quizzes and I did well taking notes this week.

  42. I would rate myself a 4/5 this week. I did really well on the quizzes. I need to start memorizing everything else we need to know for the test
