Chemistry 1A - Lecture 2

[RedVision1989]

I dont understand how he says 2 moles of hydrogen and 1 mole of oxygen make 2 moles of water. Wouldnt it only make 1 mole of water? Because its 2:1 ratio, so for every 2 hydrogen and 1 oxygen, that should make 1 water molecule (H20). Am I missing something?

[SamayBoy]

@RedVision1989 Maybe it has to do something with Hydrogen and Oxygen being Diatomic so there almost always H2 and O2

Great teaching. very experienced lecturer. clarity is awesome!

H is bad for drivers since a break in the tank could cause an explosion & if it happen in a tunnel, the people would likely be blown apart + cooked at 4000F. H has flames that are in the UV region(w/ no smoke) so the flame cant be seen outside on a sunny day - anyone remember the shuttle explosion

Pascal's wager: makes sense to me in the context of global warming and its consequences (even though there are rebuttals to the wager in the religious context).

This professor rocks, totally awesome that they release these lecture videos for everyone. Makes me want to be a scientist!

Has anyone here heard of Quick Battery Exchange. China is making Vehicles that have a quick battery exchange. KNDI, or Kandiusa.com has a quick change system that takes two minutes.

Professor If you can explode bubbles why are we not fueling rockets and or vehicles with bubbles. This would stabilize the Hydrogen in case of accidents.

The dumbing down of America/ the world is a complete sucess. How can you prove this. Look Up Beyonce. She will have about 7 million views. College Chemisty lecture 24,000. Explore your world not Beyonce's Jugs.

Thank you so mutch for uploading this.

Australian University lecturer's should be made to see this. This is a totally different style to the 'inflict the punishment of incomplete knowlege' sort of thing we put up with in our education system.

On question 2.1 ou can skip the discussion time by goin to 14:50

This is great!

[seancsnm]

This is almost easier to understand than my high school chemistry course.

[dongkyun07]

I love the fact that Berkeley would release their lectures like this, to provide more knowledge to everyone.

Is the clapping necessary??

Congratulations on your video,

I've also just completed a Chemistry Teaching Aid; a song to help students learn the Period Table.

I'd appreciate if you'd take a look;

In the meantime, I've left positive feedback for your video; I'd appreciate it if you'd do the same for me if you like my song.

Keep up the good work, and thanks in advance for your mutual support.

All the best,

I just want him to say, "And that was my boomstick."

i love his accent!

exothermic reactions FTW.

The melting and freezing of ice can take place several times in one day and does not have to be interpreted as yearly events.

I wonder how much extra these teachers get paid for making global warming plugs?

[LiquidBlunt]

@seanmPWH

prat. two dumb statements in one comment that were meant to be smart

[linekill]

@LiquidBlunt right on. lol.

[MrWolverine777]

Global warming is taking place in the north pole right next to Santa Clauses house you should know that

@seanmPWH idot!
