    It's not butane, it's propane.

    Didn't think it was too fast, but it was a lot more helpful than the 15 minutes we spent on it in class. Cheers

    Her explanation and example is so simple. I was having trouble with this all week, and I just started understanding this, the day before my first college exam!
    Just started college 3 weeks ago and have a chem exam tomorrow. Wish me luck!

    Brightstorm, thank you so much for helping with chemistry. Watching these videos while reviewing for a test has helped a tremendous amount. THANK YOU.

    You had the best video that explained exactly what I needed to learn. All the other video goes over the very basic information, and i'm only half way through the video!

    she talks too fast and then trips over own words, its an odd phenomenon, nevertheless, she is still better then my garbage chem teacher.

    • @Rayquesto
      @Rayquesto 11 ปีที่แล้ว +14

      Yeah, but at least she keeps up with her thoughts accurately. Can you imagine if she was slow and constantly could not remember what she would say about 5 seconds or so later?

    I was having a bit of trouble with the basics which was really setting me back and causing me to make crucial mistakes when doing more advanced calculations. I am really thankful to have this video to review with. :)

  • @ihatefuckinglogins
    @ihatefuckinglogins 13 ปีที่แล้ว

    I wish public schools started with math and science from the very beginning focusing about 80% of the time. Rather than wasting out time drawing and coloring. It isn't until later that we realize how important the material is.

  • @emmawong7443
    @emmawong7443 12 ปีที่แล้ว

    Balanced or not, the way to do the calculations was clear to me after I followed along. Thanks very much for your effort!

  • @alexisbecker5559
    @alexisbecker5559 11 ปีที่แล้ว

    You seem like a really great teacher! I really love that you plainly related it to things that were much simpler first giving lots of examples of the same thing in different ways, and then eased us into what we actually needed to do slowly. I don't really think that you talk too fast, but I was also using good speakers while watching this video. Great video lesson!

    The chemical equation is not balanced. It should be C3H8 + 5O2 > 3CO2 + 4H2O

  • @rakeshvb3648
    @rakeshvb3648 11 ปีที่แล้ว

    the equation that shown on the board C3H8 + 5O2 - > 3CO2 + 2H2O, is that balanced one ? a total of Oxygen should be 10 at either side but here it is only 8 on the right hand side . if it is 4H2O instead of 2H2O then the equation will be balanced.

    @RobertoEmilioRomero Although not as execrable, she called C3H8 butane, when it is in fact propane. Nervousness?

  • @sliderulelover
    @sliderulelover 12 ปีที่แล้ว

    The correct balanced equation is: C3H8 + 5O2 ---> 3CO2 + 4H2O. Your error was having the wrong coefficient for the H2O. You had 2, it should be 4.

  • @Marfig
    @Marfig 11 ปีที่แล้ว

    C3H8 is propane, not butane. Butane is C2H6. Also it's not balanced. It's 4 H2O. Propane is a more efficient fuel than Butane. It requires less quantities, burns with less oxygen and produces less carbon dioxide. The equation for butane combustion is:
    2 C2H6 + 7 O2 -> 4 CO2 + 6 H2O

    I love your video. Try to speak slower so viewers don't feel uncomfortable when you make mistakes. and let people understand the material in a slower pace. I know that there is the pause button, but it is a lot of work to pause and try to understand it at the same time.
