Need help with Chemistry? Whether you're in high school, college, AP or IB courses, these videos can help! They are also targeted to students studying for the AP Test, SAT, MCAT, DAT, and OAT exams, as well as students in nursing, nutrition, pre-med and pre-vet programs. We'll cover the introductory topics patiently and clearly, using lots of examples, analogies and practice problems. The main topics covered in this library are: Significant Figures, Scientific Notation, Density, Stoichiometry, Nuclear Chemistry, VSEPR Theory, Atomic Structure, Covalent and Ionic Bonding, Thermochemistry, and Gases.
Tyler is an excellent teacher, who can stretch out his imagination to explain abstract scientific concepts in a very simple manner. Thank you Tyler ; you are an asset to students who are learning from RU-vid.
@tdewitt451 Thank you hardly touches what needs to be said to you. As a teacher, I commend you for taking the time to go through every single step of figuring out each of these and explaining it over and over so very clearly. I was struggling until I watched your video - now it all works. It's surprising to me how simple this concept is, but how cloudy other teachers can make it. I appreciate your clarity and not making it more difficult than it needs to be. I hope I can teach it as well as you do when I get up in front of one of my first chemistry classes! Thankfully, I'll have a little while before I need to do that - and I'll be practicing between now and then! If you have any suggestions for new teachers to make concepts like these clearer and easier, please let me know!
21 zeroes after the number is a heptillion or a sextillion according to Google. Numbers names changed recently trillions changed into billions and the whole system got confused. It is still a great video though.
I love you and watch your videos after 9 and 12 years , this is sooo crazy😂!!! and I don’t know even if you still on RU-vid and if you will read my comment or not , you really really helped me I just want to say thank uuuuu🥹🤍🤍🤍🤍🤍🤍🤍🤍🤍🤍🤍🤍🤍🤍🤍
I keep getting confused by the coefficients and subscripts. Why isn't the multiplied oxidation number always the oxidation number? Like 2NO. O=-2 and not -4, but, N = +4 to equal 0. My brain wants to make O=-4 and not -2.
i dont get why they have different number of protons than electrons. I assumed we started with neutral charged atoms which means they have same protons as electrons right? so in NH4+ how did you know there were only 10 electrons if there are 11 protons?
