I am in Chem 105 which I need for my major. this class has me fucking lost,I'm a very picture thinking person and I have no idea how to like conceptualize the problems and equations for conversion factors and what not since I have literally no experience with chem from high school or anything. Anybody have chem tips to like picture this shit in my mind?
 
Why not ask your prof? You're paying thousands for college and you're asking NS for help, you gotta see the irony there.

Chem's just a weedout class. Can't hack it maybe college ain't for you.

Orgo’s the only weedout class really and that only applies to premeds.

OP i gotta relearn some of this shit for a standarized test so post some problems and ill try to work through them

You're missing the point. They make all sorts of majors take basic chem. Of course ochem is harder but it's far more major specific

Part of the major because its important to learn, not to make people who have a hard time with it suffer and drop out
 
Ask the professor or the TAs? Or read your book. Presumably this is the spring semester and you took 104 prior to this no? I assume you're past balancing equations and such and on to acid/base equilibrium or redox or something of that nature? Or basic atomic structure?

If you don't like your textbook go to the library and check out a different one. But in my experience a lot of chemistry books are actually pretty good.

^^ this for sure,, if youre not much of a reader, there are always people on youtube you can help you visualize through it

Shit I didn’t even think of my textbook lmao, gotta have some good shit in there, I sent my prof an email to schedule some extra help, also just found out my homie is in the same lecture
 
Who knew a thread on the internet of some poor college student asking for help would end up like this? Anyways, just be smarter OP
 
If you're having issues with converting, the best way to write it out that's similar to a picture is ratio factoring. Basically, write every value and unit as a fraction and just start canceling shit out. Even if something isn't a fraction, just put it over 1 for conceptualizing. You can use as many conversion factors as you need to get to your final unit. I learned this in high school chem and used it all the way through undergrad for civil.

Here's a video of how it works (9:22 for examples):

Looks like Khan Academy to me

I'd agree, for somebody going into natural science and outdoor education I think chem is pretty important

Got a degree in forestry with a minor in plant biology. It is and it isn't. Intro chem classes are mostly just weeder classes. Generally speaking, intro chem classes are going to be way too broad, and only last a semester or two, so you never have time to get down into the mud and actually learn concepts to the point where you could use them.

Just make sure you understand the basics and pass the class. It get's a lot more fun down the road when things get more specific

I bet if you quized uni seniors on the shit that they should have learned in their intro classes 80% of them would fail. What matters is what you use and intros are always way to broad and way to short to learn anything meaningful besides the basics. Hence why they are weeder courses. They're there to see if you can handle the college workload. Chem 101 at my university had a god awful pass rate and all those people where engineers

Nah, it's also a good way to broaden students' interests. For example, I had a good friend switch from mech engineering to biomed because he took a general bio class, saw the similarities that he liked, and switched major. So some of those broad, entry level courses really have the main objective to introducing people to more specific fields or topics that they may want to focus their education or work on later.

Shit it actually is vsepr i already lost lmao

but really just let khan academy hold your hand through the whole semester and itll all be alright

Chem was like the only thing that came easy to me. I only took a couple 100 levels like you are in so I probably would have gotten owned in upper level but I was smart enough to not attempt.

I feel that once I get a hang of it I’ll probably like it, I usually dig formulaic shit but so far this nut is a tough one to crack
