every time my chem teacher would play one of these videos in college everyone would always point out how I look like a younger version of you, so thanks for the A's in uni, but at the same time couldve done withought the years of time travel theories everyone would always joke about when our teacher was too lazy and had you do her job. Also the grams per volume thing is alright because its water and 1 L = 1 kg, so its 30g of H2O2/ 1kg of H2O, but when it starts messing with solvents that aint water it gets annoying working backwards from volume to mass or mass to volume to figure out molar ratios.

The
I-ve been watching these videos all day and I-m reading the comments and getting mildly annoyed
Yes
Hank is AWESOME
and crash course is freaking great and comprehensive
I-m prepping myself for my first college Chem course right now and if I understand these concepts I-ll be well on my way
But
You guys this isn-t a substitute for Chem class, period
You need lab
You do
You really need lab
So you can see the reactions yourself

science-y
Feel free to correct me if I've my facts wrong.
Around 3: 25 to 3: 35. he mentioned that sugar molecules get split up. but this doesn't happen cuz it's a covalent compound.
And it obvoiously doesn't have any positive or negaitve part cuz they're sharin'.
But if it were to be nacl. then okay cuz you're gonna separate it into na+ and cl-.

Also, % weight by volume is absolutely one of the most common ways of describing solutions in chemistry. If someone says -x% solution-, they mean percent weight by volume. And lots and lots and lots of solutions are described that way

Narrator you-re way too animated, you-re like half screaming and bc I-m far sighted it-s really hard to understand, can you not laugh-scream please. And the intro music is like trying to burst out my speakers. TOO LOUD

This is a good video for explaining the background of water and solutions. But can post more videos on questions solving? As i think this is is where most students are facing problem at.

why do i keep watching these? I never learn anything. It's so horribly done, in such a catchy, clean cut way. These videos are what I watch when I pretend I want to learn something lol

is the mixture of soap and water Homogeneous or Heterogeneous? I'm thinking that their mixture is a colloid and well colloid is Heterogeneous, so soap and water is Heterogeneous?
