I love what you do! But, this time a few errors slipped in, so let’s correct them: Two things: 1st thing: @7:22 you have a slide that lists the Standard Conditions: T = 25 °C C = 278.15 K P = 1 atm = 103.25kPa That is a slide with a couple of whoopsies, that mainly look like typos in the temperature, it is split on two lines and 273.15+25=298.15, not 278.15 in the pressure 1 atm = 101.325kPa not 103.25kPa What I think the slide should have said is: T = 25 °C = 298.15 K P = 101.325kPa Sidenote: there are several standard conditions, the one referred to in this video is SATP - Standard Ambient Temperature and Pressure, but I can see how this distinction is unimportant for this video. 2nd thing: @10:16 Hank says: “All that energy locked away in chemical bonds and then released as heat to my aching frozen fingers.” I have to take issue with this phrasing, as it perpetuates a common misconception, that energy is stored in bonds; thus, breaking them releases that energy. That last part is not the case: Breaking bonds require energy. Forming bonds releases energy. If you look at the reaction equation @9:22 4Fe+3O2->2Fe2O3 you can see a net gain of bonds. While all bonds are certainly not created equal, the heat to Hank’s hands comes from the formation of bonds between iron and oxygen, not from the breaking of dioxygen bonds or metallic iron bonds, unfortunately his sentence implies otherwise. I am aware this video is over 4 years old by now, but I still hope it will make it to the CrashCourse people. If you are not such a person, and still read all this, please like to increase the small chance that it gets seen.

I had no idea what they were doing, but now I do they did this calculations this is ridiculous with a few episodes of crash course chemistry I understand in chemistry about as much as a few friends of mine understand from studying it in school for a year and a half.

Some do and so the container has to be chosen carefully so that it doesn't react or dissolve. It turns out that glass (and many plastics) are extremely inert and make really good containers for doing chemistry. The molecules in the glass are so tightly bound that they have no inclination to leave their comfortable surroundings and wander off with the stuff in the beaker/flask. HF is something that actually will react with glass. Also note that we don't generally use metal reaction vessels.

Gaurav Agarwal He said C = 278.15, so 25C = 278.15 + 25

Castillo Dazš Firstly, he implied that the temperature was 25 degrees, which he said was 278.15. WRONG. He then said STP pressure was 103.25 kPa, which is also wrong. STP pressure is 1 atmosphere which is 101.325 kPa, check google.

Hello Crash Course team and everyone behind this awesome project, I just want to let you know that I've tried to contact on you for having permission to create portuguese subtitles for some episodes and since I got no response, I got a little ahead of myself and began to do it anyway. I want to apologize and want to let you people know that I'm trying to credit you everytime. Well, that's what I wanted to say, if I'm doing anything wrong let me know and I'll take down the videos. Best wishes, me
