Hey guys, I’m making a couple of last minute changes to the syllabuses for this week, so I’ll give you a copy of the revised one Monday. See you tomorrow!
I don’t understand the relationship between mole and molar mass. On tonights home work it asks us to convert 1 molar mass CA into grams. I don’t understand and the example problems aren’t helping me much.
Will – Molar mass is the mass of one mole of any element. One molar mass of calcium would be the mass of one mole of calcium – or the avg. atomic mass in grams.
do we have to do science in the news this week?
Michael – Not this week. You’re going to do #58 at the end of the chapter instead.
Ms. Skinner~ I’m looking forward to your lesson video. That’s so helpful.
I agree with Lily! Those help out real good.
When will our Chapter 7 test be?
Anna – In a couple of weeks, at least.
Hey, Ms. Skinner, I already made some flashcards for the Polyatomic Ions! I’m going to be ready for this quiz on Tuesday!
Grace – Great!
Ms. Skinner, when it says on the syllabus to do only B and C on parts, it means on every part that has a B and a C, right?
Adam – Yes. And all the other questions that don’t have parts.
Mrs. skinner i’ve made my own quizlet account and made flash cards for us to use online.
Brandon – That’s great! Thanks!! 🙂

Are we supposed to do the review questions for section 1 or the chapter review?
Allison – It’s the questions at the end of the chapter. Holler if that doesn’t sound right.
is the only thing we have to know for monday the polyatomic ions???
Ally – Yes. Good luck! 🙂
