Watch the Eclipse on April 8, 2024 - Eclipse Types and Phases - Fun Things to Do During the Eclipse
Hi Everyone!
A Total Solar Eclipse is coming up on April 8th, 2024. If you're close to the path of totality, I really suggest you try and see it! Here are some things about eclipses in this video :)
1. The three types of eclipses
2. The phases of an eclipse
3. Fun things and experiments to do during the eclipse!!
Cheers :)

Resonance Structures - What to do with Lewis Dot Structures for Polyatomic Ions
zhlédnutí 833Před 3 lety
In this video we look at how to do Lewis Dot structures for polyatomic ions they have RESONANCE structures... this just means that there's more than 1 way to draw them because the electrons are "delocalized". Sounds confusing, but I promise, it's not. In some of these structures, we can also "force" some atoms to break the octet rule - but that's okay because electronegativity will help balance...
Polar and Nonpolar Bonds - How to Tell if a Molecule is Polar or Nonpolar?
zhlédnutí 3,3KPřed 3 lety
In this video we look at the next step in electronegativity polarity We need to be able to determine if a bond is polar or nonpolar, and we use electronegativity to do it. Make sure you're solid in understanding your VSEPR models and molecular geometry before you try to figure out if a molecule is polar... the SHAPE of a molecule can determine the POLARITY of the molecule. Just watch out for that!
Electronegativity - What is it? And the FONCl BrISCH rule
zhlédnutí 2,5KPřed 3 lety
In this video we look at electronegativity - the ability of an atom to attract electrons. This is so important to understand because it's the building block for polar/nonpolar molecules. Make sure you get this! Good luck :)
VSEPR - Molecule Shapes - How to Find Shape a Molecule Takes - Valence Shell Electron Pair Repulsion
zhlédnutí 551Před 3 lety
In this video we look at the VSEPR model and how to figure out what shapes different molecules will take. You must look at the number of atoms bonded to the central atom AND the number of lone pairs attached to the central atom. Then you can figure out if the molecule is: 1. linear 2. trigonal planar 3. tetrahedral 4. pyramidal 5. bent Those are the main 5. Yes, there are some molecules that br...

How to Double and Triple Covalent Bonds - Same 4 Easy Steps
zhlédnutí 20KPřed 3 lety
What happens when you need to make two or three bonds to the same atom? How do you show it? It's easy - just bond the single electrons together (follow the same 4 easy steps as with single bonding) and if your molecule looks wonky after matching up the singles... just redraw it! You got this!
Covalent Bonding Intro - 4 EASY Steps - What is a Covalent Bond? How do Atoms MAKE Covalent Bonds

In this video we look at the basics: What is a covalent bond - and how do we make them? 4 easy steps to follow: 1. count up all the valence electrons from the individual atoms 2. draw out all the Lewis Dot structures for each individual atom put the atom with the most single electrons in the middle 3. Connect the single electrons to make a covalent bond 4. Check your work. Make sure you end wit...

she cute fr
Amazing video, straight to the point I understood this so well. Thank you sm
Great explanation mam 😊 Thank you so much🎉😊
Would be much easier if the products wre a differnt color, looks like stuff just flying around lol
She keeps saying what the heck 😂
Why are both sides divided by 2800?
Thank you i will pass my exam now🎉🎉🎉
Thank you 😊 your tutorial video is awesome
Wow thanks! I've just learnt something new! ❤
You are amazing
So helpful
your so funny with your hoorays like im laughing while doing chemistry. honestly beats crying so thanks miss girl for real
Ur besttt ur videoss meanss a lott to uss thank uuu ❤❤❤❤
thank you so much for the calculator tip i was so lost doing my practice problems
Why are there no more uploads since 3 years?
You explained it so well. My doubts are now cleared thank you mam! :)
Just learned the last part H❤
Thanks l like writing system ❤
Great explantion❤️🥰🙏🏻
5:00 Wrong! xx=x^2 (x to the second power, then getting the square root of both side will give you 1.00ox10-7, elementary middle school math!
In, N2 + 3H2---> 2NH3. Here NH3 is a covalent bond meaning it is not made of ions so none of the elements is gaining electrons or losing them. So only Reduction is taking place. Please correct me if I am wrong. This has been bothering me for quite some time.
thank you
Straight (and clear explanation) from Straight Science ❤. Thank you ma'am .
Wish I’d known this. Looking forward to the next one!
Thank you soo much you made this very easy to understand for me ❤️
Thank you for the explanation and effort, even with the baby calling for your attention. Thank you
Great ❤.. thankyou for the help ..
Thank you for your video!❤❤
I have a question how do you get 2.96 you multiply or you divide it?
This is really helpful, thanks
Thank you so much mam !!! Our teacher also taught us a standardized result M=10xd/m.m {M=molarity, x=percentage by mass d=density m.m=molar mass}
10:49 another note, should be -5, not -6
Combined Gas Law and ideal gas law the same ?
Wow ❤️, I'm impressed with your teaching; it's so amazing
I wish you were my Professor, thank you so much !!!!!!!! You are gifted to say the least, thank you for sharing your gift with us !

ILYSMMM THIS IS SUCH A NICE TRICK ILYYYYY MWAHH
YOU ARE LITERALLY A GENIUS ILYSM OMGGGGGG
I am a grade 11 and I take chem 20. I miss a lot of lessons from school and when I get home my notes does not help me at all so I search online. Nobody, explains and clarifies the lesson as you do. Like it is very easy and simple when you teach them. Love you your videos and they are helping me a lot. Thanks 😊
Hooray! Good luck studying! You got this
The best learning video ever my teacher doesn't explain like this you are the best ♥
What of about 1.556 please what will you multiple it with
3.08 was wrong answer
Excellent
