Naming Covalent Molecular Compounds
Vložit
- čas přidán 14. 04. 2015
- We'll learn how to write names for compounds that are made of two nonmetals, sometimes called binary compounds. Binary compounds made of two nonmetals are called covalent or molecular because the elements are held together with covalent bonds, and they make molecules. In order to name them, we use the element name for the first element in the chemical formula, and then we use the -ide name for the second name in the chemical formula. Greek prefixes to show the number of atoms of each element, and these are put in front of the element names.
IMPORTANT: There is a small mistake in this video. At the beginning, I show the Formula Fe3O2 and call it "Iron (II) Oxide." The correct formula for Iron (II) Oxide would be FeO. Sorry about that!
+Tyler DeWitt is okay i still love you tyler
+Tyler DeWitt DUDE I Laughed out loud when you said "I forgot to the name in the last one, and this is just *so* satisfying. So i did it slowly to make up"
+Andrea Terblanche I think it applies in OXIACIDS. In aqueous phase, if it ends with -ATE then you'll have to replace it with -IC Acid. Example: Sulfate then it'll become Sulfuric Acid. And anions ending with -ITE will be replace with -OUS Acid. Example: Sulfite then it'll become Sulfurous Acid.
+Tyler DeWitt Lol i tried to solve it and it didn't come out right and got a little confused so thx for commenting this. I wish you were my teacher you are really good
lol i sit there for like 5 minutes thinking im crazy because it didn't make sense to me, then finally saw this comment.
This here is the definition of what a great teacher truly looks like.
You legit cut my studying time in half!!!
you could say that in a negative way or a positive way
your passion for teaching and excitement for chemistry is infectious. Hopefully my exam in a couple days goes well. With these videos you've made, I truly have no excuses.
Scored an A in my last test solely by watching your videos haha, no help from textbook or teacher whatsoever
I wish to meet him personally!
Anyone else notice this guy did a TED Talk(S)? Saw it in my watch later.
Yeah! I know I watched it too!
Sidd my teacher won't even help if I ask
😯
dude, you're better my high school teacher at teaching.
+Jacqueline Garcia I know right?!
Lucas Cousin you 'too' need a new English teacher
Lucas Cousin rip
@Lucas Cousin You messed up too..
@Lucas Cousin sheesh, roastedd
Drinking some dihydrogen monoxide when watching this video
lai yong hui some how it took me some time to figure out
lol
i thought that meant bleach before realizing its H2O
I prefer hydrogen oxide or hydrohydroxic acid myself.
With hydrogen prefix should not be used...so it is hydrogen monoxide
I wish my teacher was as good as you are. thank you so much for the videos!
Why is it I can watch 20 minutes worth of CZcams videos and pass a test? But when I listen to the teacher for the entire year I fail???
Anyone else here because their chemistry teacher sucks at teaching?
Yes
yes lol aside from sucking at teaching, she's always absent
Hell yes, my teacher is horrible
ArashiyamaBaby does your teacher own a moonshine plant
My teacher copy and pastes sentences from the book to the board for the whole period without explaining a thing.
the way he teaches us shows that he really wants us to learn, thank you so much for this video i truly appreciate it
You've saved my chemistry grade. Ily
Very excellent explanation ❤️❤️👍
ima slay my chemistry final tomorrow
Hani Xax ik its a bit late but how did you do?
did you?
im 2 years late, did you pass?
She’s out
Can you come slay me next babygirl?
I am currently coaching my granddaughter during the lockdown. Because I live in Spain, and she lives in the UK, we communicate via iphones. I have to say (as a chemistry graduate myself) that this has been one of the best introductory lessons I have seen. Beautifully prepared and perfectly delivered. Well done that man ! Regards from sunny Spain.
I have a chemistry degree and I can tell this guy is teaching awesome
U didnt learn much didnt u
You are truly a lifesaver. Thank you very much for your amazing content.
i really wan to say thankyou for these videos. everytime i watch school related videos i get bored and tend to tune out the information. your passion for the subject is infectious and i find myself really engaged with you hand gestures and good projection.
This might be your best tut yet that I've watched (and I've watched 'em all up to this point as I go through my CHM 101 class). STEPS!! Who doesn't love steps! Steps make everything clear and digestible--and DOABLE! Thank you, thank you, thank you!
You are so great. Very organized and thorough! Absolutely emaculant! Keep it up the exceptional work!
its too nice help me a lot thanks 😇😇😇😇😇
WOW! You cleared up the million questions I had in 10 mins. All million of my questions came from a 4hr lecture I had in Chem today
.. Thank you
This dude taught me so well for chemistry
Thank you SO MUCH! Your videos have been immensely helpful in my understanding of Chemistry. I sit in class completely lost and confused all day and then come home and watch these videos and get it on the first try. You are an excellent instructor!
These videos are teaching me more than my professor/book/homework etc has been able to. Thank you Tyler!
I could cry happy tears from watching your perfectly explained videos. Thank you!! Thank you!!
Thank you so much for these videos. I have been borderline freaking out in my chemistry class because I wasn't grasping the full load of information given. Your videos have helped me tremendously! While I am watching I am also taking notes and those notes have helped me more than once in class. Keep doing what you are doing, my grade depends on it! :)
OMG thank you so much. you really explain it so much easier than my instructor. You Don't rush and I Appreciate the notes I take away from these videos. Like a light bulb went off!
I never take chemistry ever and I'm 50yrs old trying to help my son with his chemistry. I'm glad I found you. Not only I'm getting better at this but my son is improving his chemistry. Thank you so much
This was so helpful. I understand the concepts better than sitting in class. Thanks Tyler!

GENIUS
I was away for most of our chemistry unit and thanks to you I'm ready for my exam today
Thank you so much!! My teacher doesn’t do a good job at teaching, and this helped me out a lot!
These videos are the only reason I am not drowning in chemistry.
I just want to tell you that you're an amazing person(teacher), Tyler! I've been telling some of my classmates about your videos. I got a 96 on my first Intro to Chemistry test, and I don't doubt that you had a huge impact in that! =)
Lrtx82 aww congrats on your test! He is really good. Alot of my classmates always brag about how well he explains stuff
8:35 earned the like
bless you for this knowledge man
Love how you learn and get a bit of personality so it makes things more laid-back. College chem can get very stressful due to deadlines and I appreciate the laugh I got from forgetting to circle one and making sure to do it on the next.
these videos really save me hours upon hours of reading from my confusing and expensive text book. Tyler, your work is much appreciated even 3 years later!
Bruh I literally learned more in 5 minutes than from my teacher this whole chapter
I shouldn’t be able to say that
Hi Tyler thank you for all your amazingly understandable videos. I wish my professor taught like this =) ...my favorite video this far is " let's party all night long with mole ratios!"
There should be a CZcams University Graduation Certificate because your videos are actually WAY better than how my uni professor teaches.
You are an excellent teacher and have helped me figure out scientific topics which have genuinely made me cry from frustration. Thank you so much.
im only here because my teacher doesn't teach us anything, she just sends us to tyler lol
you are my hero bro, great lecture!
I watched this when I was in 10th grade and now I'm in my 1st year in college. You're my lifesaver! Thank you so much sir! God bless you.
I was looking for the most recent comment lol. But this man helped me with math and now chem. I'm forever grateful for the homie Tyler
I completely love the way you teach but above all when you smile. Thanks for teaching :)
This helped me SO much.
My teacher and Khan Academy isn't helping.
thanks a lot Sir ;-)
This is the art of studying and watching your videos made my head not stress
You’re really helping me. And I couldn’t have done this without you, as simple as it seems, my teacher isn’t good. Thank you so much
thanks
Is that correct in 1:09? Has iron(II) oxide Fe3O2 formula?
Laura Sandor I was wondering the same thing.
Laura Sandor Well looking at it, Oxygen has a charge of -2 and Iron 2 (or ferrous as I prefer to call it) has a a charge of +2 so while you could technically have a compound like that it would be unstable and would end up reacting with the oxygen in the air to produce Ferrous Oxide.(ferrous oxide is FeO you would just have 3 molecules of it)
No
I feel like this guy is going to be my new friend for the next 2 years. Thanks for the videos!
Thank You SOOOOOOOO much for all these videos. You have absolutely no idea how much this has helped me in a MAJOR way. I feel like I can actually survive this test lol
Easy to remember Penta, only because of PentaKill. LoL people will understand.
or penta because a pentagram has 5 points.......
the 4 (tetra) messes me up cause of Quadrakill
adopt me thanks
This man has helped me ace chemistry finals this year without opening a text book. Thank you alot Tyler we love you man!
you are amazing thank u so much for this. so straightforward and easy to understand. i learned more in a 10 min vid than an hour of my teacher talking.
Why can't teachers teach like you? I like my teachers, but you explain it so simply and I immediately understand. Thank you!!!!!
i'm so happy, excited, and proud to watch someone has a good knowledge and a super way to reach an idea to other . Thnx a lot.
Thanks for the videos. It helped me with my chemistry midterm. You sure have a talant to patiently explain chemistry to our understanding . Thank you !!!! May God keep you safe and secure so you can be a great help for many people around you!!!
The way that oxide kept moving lol... I cant thank you enough tho you teched me more in ten minutes than a whole hour when it comes to my actual science teacher... Love you my guy
I never thought I would smile during a chemistry lesson. Thank you so much. You make this so easy to understand! Teachers need to study your methods.
just really wanted to say that this helped SO MUCH for me. The way you put the information together was smooth and easy going. My teacher speeds through lessons so I often have a hard time keeping up.
I love the passion for teaching you have! That's the difference berween high school teachers and you.
bless you man, every student needs a teacher like youuuu
Thank you for being my second Chemistry professor. You've helped me mucho.
Your videos help reinforce what I learn in class. It is greatly appreciated. Thank you!!!
Hello! This channel is amazing, my uni lecturer is so vague with all of his lectures. I see what he is teaching and then I jump straight onto this page, so well explained!! Thank you so much. All the way from Brisbane, Australia.
Loved the way you teach. I could feel that you really love what you are doing. Thank you for your explanation. Things are clear in my head now.
I mean no disrespect to my current instructor, but I just discovered this channel and these videos have taught me more in a couple hours than I've learned in 3 weeks. To be fair, my class is online and I'm confident my instructor teaches more thoroughly in a seated classroom setting but I appreciate these videos.
Thank you for explaining this so clearly. My chemistry teacher zooms right past all these details and so these videos are super helpful.
He’s out here saving lives and by lives I mean getting good grades 😂
You teach way better than my professor hands down. Thank you.
I'm in college and you're better than my lecture, slides and textbook combined. Got my exam tomorrow morning, wish me luck!
You are the best . Now I can teach my son the same way you explained , clear and precise . Thanks a lot for posting such great videos .
I just would like to thank you for making this video very simple to follow. I have been strugging with naming compounds and thier formulas. So thank you again! :)
i have seen most tutorial videos but Tyler is the best online tutor.
I didn't understand anything for half of the term until I watched your video .. thank you so much!
I have an exam tmrw and I'm so nervous about forgetting everything I learned from you Tyler!
You're excellent and I wish you were my professor.
I love this guy, makes chemistry seem like a cool breeze... love the simplicity. I wish my professor was more like this but I guess they have to pace through it on college level standards.
look at all of the views on covalent bonds. love your work and great just to come back to this type of easy to understand teaching. keep doing what you're doing.
You are the best . Have never seen such fantastic teaching skills before . God bless you .
literally thank you soo much, you're pretty much the reason I'm passing this class!!!
Tyler- I use all of your videos in my Chemistry Class. They are a great addition.
man, you're great. the format of these videos are so efficient, easy to understand. I just hopes you'd have specialized on Quantum Physics too and explained it in the same format :) Good job, thanks a lot !
Commenting 5 years after posted but u are very good at what u do and are a life saver
OMG. My Prof made this SO DAMN COMPLICATED. I was feeling so bummed until I watched your video. You just restored my faith!! Thank you for such a clear explanation.
wow thanks man! I watched literally less than 20 seconds and you had already answered my question! You're awesome!
Very helpful videos. It's a lot easier for me to study for my medical admission test this time now that I have studied with you! Thanks for keeping up with posting amazing videos!
You have helped me so much!!! All of your nomenclature videos are amazing
Thank you for your content. Tutoring my daughter today in freshman chemistry. She has dyslexia and your instruction is simple to follow. Thank you for the lesson.
Thank you for your videos, I watch only your videos because you make it so easy for me with no prior chemistry experience.
Your videos are GREAT! Thank you for taking the time to break down what would otherwise be very confusing (intro) chemistry problems :) Please continue to make more videos!
Thanks so much. I will recommend you to the rest of my class. This helped me so much!
This guy is a GENIUS at teaching! Thank you Professor Dewitt!
انت احسن واحد يشرح
You are the best one explains am from KSA
Your videos really help me understand the subject soooo much better. Thank you!!!
Tyler thank you for these videos. They are helping so much. All the best dude.
I have an exam tomorrow and my teacher can't teach but you can and it saved me!! thanks Tyler I appreciate it.
This video is phenomenal! Definitely using this approach when I start nomenclature on Monday.
How has this dude not hit a million yet he’s been on CZcams for a decade
