CHEMISTRY: So how many water molecules are in that drop? Here’s the lecture from today on using molar mass as a conversion factor. You did a great job on the problems! Keep practicing them so you don’t forget!
By the way, were you ready for a quiz today? What about tomorrow? Don’t give up – keep working on memorizing polyatomic ions, acids, and the chemical names for those common substances you researched. Have you tried making a song?
🙂
Ms.Skinner, Miss you today~
We don’t have Science in the news today, do we?
I hope we do more practice problems on moles and molecules .I need more help!
I’m finally understanding how to solve for the moles and atoms in chemical formulas thanks to all this homework!
Thank you for this video, it really helps.
Thanks for posting this video, it helped me catch up on the items we didn’t get to yesterday when you were out!
I’m starting to understand this lesson now, thanks to the video.
thanks for this mrs skinner
This video really made the lesson more clear to me.
Im really starting to understand this part of the chapter. thanks ms skinner!
When are we going to have a help session?
Mrs. Skinner will we be doing a new mythbusters next week?
The vod cast really helps!
The worksheet we did last night really helped!! i will definitely be studying this weekend!
when is our part 1 test??
Ms. Skinner, are we going to have a science in the news next week?
Mrs skinner did we ever decide on when the test was????
Enjoyed the lab today!
Enjoyed the lab today, also finally figuring out a way that will help me learn the memorization better. Thanks for the encouragement.
I really am starting to understand on how to do these types of problems. The Q formula helps out a ton. Is there any other fomulas that are similar that we may use in the future?
The lab was extremely helpful with working out problems dealing with molar mass and whatnot.
Ms. Skinner- Will we have another quiz on memorization before the test?
