My goal is to help you understand chemistry by breaking down difficult concepts into pieces you can understand. I've taught thousands of students and no matter how much you're struggling, I promise you can learn this stuff if you dedicate yourself to learning it and get help from the right people!
RUclips has taught me more than any chemistry teacher will. Thank you so much for this video
Trinity Medina omg so true
You're also way more focused and not sitting next to your friends.
Yes true plus this video is part of my exam
what will happen if your chemistry teacher saw this?
@Modeler what's his channels name
who else is here to re-learn entire chem class for the exams
No one
Preparing for entrance examination
Noo way i am
Sadly me but I’m learning cause I got not clue what’s going in
Me totally me for my coming exam this is th 2nd unit of my book.
My teacher gave us a few pages to read but I have adhd and not only could I not focus but I’m a visual learner and i could NOT organize my thoughts I had no idea what I was reading. This was so helpful thank you so much
yay so glad to help! good luck in your course!
Same here I am a hot mess when it comes to focusing!
i aint readin allat
When RUclips can explain it better than ur school can👀
mood
Lol 😂
You probably just don't pay attention
I am literally only here for school. This is how people are getting views these days.
ong
I wonder if this kind of things can get me a job?
Kinda sad to be honest
Same
Time for some online learning y’all
I enjoy quarantine but i don't like the online school learning
If pure substance has only made up of only one kind of Atom why does it have a compound? I mean, Compound has 2 atom that is chemically joined together. Pure Substance has only one kind of Atom so the properties of it has also to be only one kind of atom. Please answer it would be much easier for me. Thank you so much!

Well mixtures are like an area of two types of elements or compounds. Certain types and amounts of elements can combine or change into other elements. Those combined elements are still elements, but since they are combined they are now labeled compounds. If you look at the picture you'll see that the mixtures are yellow dots and green dots, (Or the element and compound on the other one), while the others are a single element or compound. If this still confuses you then just think of the compounds not as mixtures of elements but rather elements themselves. Hope this helps.
Umm... Pure substances are made of one type of atom or one type of molecule . A compound has same type of molecules because they have a fixed ratio. So they are pure . I don't know much but hope that helps.😊
So steel compound kyo nahi ho sakta?
These videos are more helpful and educational then the teachers are teaching you .
this saved me i have an exam in 1 hour
hope it went well!
Thanks a lot from India
you're welcome! good luck in your course :)
I literally came here because I was listening in class and it's like the information went in one ear and through the next and I didn't understand crap I'm starting to think somethings wrong with me
Repetition is your friend! Keep trying with different videos, come back to the ones that help, don’t worry it will slowly sink in!
Homogeneous mixture: 03:33 Heterogeneous mixture: 04:24
i have a chemistry exam tomorrow and i really needed to brush up on this topic, and this was truly helpful. thank you.
did you pass your exam?
Cheese Bslls the world will never know
@@cheesebslls6203 haha, yes, yes i did.
@@frankthescrub8933 well :)
@@ann.178 congrats!
Thank you so much. I learned more in 9 minutes than 2 hours of looking at a textbook!
What is the difference between matter,composition,property, atom,molecule,substance, impure matter, mixture, physical property, chemical property, element and compound
This should have a billion view
hahaha thanks!

hi
hi random person scrolling through the comments because they don’t want to pay attention to this video that their teacher made them watch
I brought snacks 🍪🍩🍿🍭🍬🍫🧁🥧🍦🍨🧃
did i ask
Element: 00:57 Compound: 01:32
Than you!this really help especially with this virtual learning .
Ty
Thanks so much i was already so confused on the first day of chem but now i understand!!!
Omg thank you so much I have a huge test and this saved my life! I had to translate all of it to French but I understood it from looking at the pictures so thank you again this helped a lot😁
Oh yay!! Good luck on your course!
thanks for the video!

Is a cake a mixture if so is it homogeneous or heterogeneous
とてもわかり分かりやすかったです。
Thanks for explaining this
Thanks for the great video!
so glad you liked it!
There’s two different types of matter pure substances and mixtures pure substances have two different types of elements and compound so does mixture homogeneous and heterogeneous an element is what is on the periodic table and is made up of one type of atom and compound is a chemical bond making a bunch of different atoms come together and make a molecule homogeneous is when everything is evenly distributed and heterogeneous is when you can clearly see it is split into different groups
iaint readin allat
It is the helpful video
And I understood much better
Than I understand in class 🤣
U are amazing
Thank u for explaining so well
U are a osum youtuber
Never close that
🎉⚡💥💯🔥
Wow
Thank you! This was very helpful. I’m taking chemistry (blended learning class). I have to teach myself lol. However, your video helped a lot 😘
I'm glad! good luck!
@@RobinReaction robin reaction. Com stupid voice
@@mbplumbing4499 yep
Can you clarify the difference between molecules and compounds as you seem to be using the terms interchangeably
Thank you! I love this video
yay glad i can help!
i dont
Thank you teacher
Thank you so much you are a great teacher 🤭.Is water really a pure /element?
Revisiting my past through RUclips. Thank you for the knowledge!
you're welcome! congrats on getting past chem!
Thank you so much, this helped a lot
ruclips.net/video/mdDQ5w59GyU/видео.html
Thanks! That really helped!
Thanks for the great explanation 🙏😊😊😀
In the examples, I would argue that water is a homogenous mixture, since there is almost no place in nature where water doesn't have anything dissolved in it.
Water is a substance because it is made of only two types of atoms. Tap water is a mixture because it has other impurities dissolved in it.
0:25 I thought light was made of protons.
Robin defines an element as a type of atom almost certainly found on the periodic table, but I have heard and element is a substance that cannot be broken down into 2 or more smaller substances with a simple chemical process.
yes those are both correct, they put the types of substances that cannot be broken down onto the periodic table! I think you're thinking of photons for light!
So faR this was the best video on this topic💞.simpLy amaZing.
If ur here from class
i understand everything in chem so far except for this that’s crazy that I can do everything we’ve learned in 6 months except for this
I’m in the same boat as you. I didn’t study for my first chem test but did for the other 3. So now I understand a good amount but not sig figs and mixtures
Good video
thank you! good luck in your course!
Isn't aluminum foil a mixture rather than an element?
You simply helped me clear my silly confusion..thanks a lot mam
i love your channel! so clear and helped me so much for my chem test tomorrow!
Thanks for sharing. Nice way of explaining.
Thanks mam I know everything now
very useful thank u
Nice video
Thanks! This helped me understand my textbook/homework
yay!
THANK U SOO MUCH
What are the reasons why pure substance cannot be easily separated unlike mixtures ? 🙆♀️
because they are chemically combined
it would require a chemical reaction to seperate a substance
Bc pure substances are chemically combined and mixtures aren’t
bless this video
Why u guys dislike dis vid it is helpfull
You the best
Thank you. Very helpful.
This was so so so helpful! You explained it really well in a way that made sense, so thank you so much for putting in that time and effort to help others.
Great video
wow totally learned something ✌😎
Are ionic compounds molecules too?
yes!
😊 thanks 🙏🏻
What's the difference between compounds and homogeneous mixtures?
I think a compound is a mixture of many elements and a homogenous is a mixture with just 1 substance
verygood it helps
Thank you
Learning before a day from my exam :/
good luck!
Thanks for an amazing video! I am able to distinguish whether something is a pure substance or a mixture. I find it a little difficult to distinguish between homogenous and heterogenous. For pizza, for instance, I thought that it would be a homogenous mixture instead of a heterogenous mixture because it could have the same level of consistency (this is based on how you scatter the toppings).
Meenakshi Sundar Rajan how you can look at it is if you can separate it I think
Heterogenous - Has a non-uniform composition, the particles(materials) in the mixture are visible, depending on the mixture it can be seperated, an example; salad.
Homogenous - The particles are well mixed and its componenets are not visible and you cannot tell what it is made of or what the particles are since it is all mixed well
(Don't know if I explained this good enough but here you go)
if its cheese pizza then technically its a homogeneous mixture lol
shut up
@@logancoyman221 Whoa... is that what you call people who have traditional names? And you are implying that we westernize our "stupid", "weird" names, so that it sounds more decent?

Thank you so much this cleared all my doubts
hi i need help😔 i just had my breakdown and i cant even answer any questions right now😔 i badly need your help... if ever you can read this, can you please help me answer the question "why is there a need to classify matter?" im sorry i know it sounds too easy but my mind won't cooperate right now and i have soo many requirements as of the moment...
the answer is very simple. In classical physics and general chemistry, matter is any substance that has mass and takes up space by having volume.[1] All everyday objects that can be touched are ultimately composed of atoms, which are made up of interacting subatomic particles, and in everyday as well as scientific usage, "matter" generally includes atoms and anything made up of them, and any particles (or combination of particles) that act as if they have both rest mass and volume. However it does not include massless particles such as photons, or other energy phenomena or waves such as light or sound.[1][2] Matter exists in various states (also known as phases). These include classical everyday phases such as solid, liquid, and gas - for example water exists as ice, liquid water, and gaseous steam - but other states are possible, including plasma, Bose-Einstein condensates, fermionic condensates, and quark-gluon plasma.[3]
also, Usually atoms can be imagined as a nucleus of protons and neutrons, and a surrounding "cloud" of orbiting electrons which "take up space".[4][5] However this is only somewhat correct, because subatomic particles and their properties are governed by their quantum nature, which means they do not act as everyday objects appear to act - they can act like waves as well as particles and they do not have well-defined sizes or positions. In the Standard Model of particle physics, matter is not a fundamental concept because the elementary constituents of atoms are quantum entities which do not have an inherent "size" or "volume" in any everyday sense of the word. Due to the exclusion principle and other fundamental interactions, some "point particles" known as fermions (quarks, leptons), and many composites and atoms, are effectively forced to keep a distance from other particles under everyday conditions; this creates the property of matter which appears to us as matter taking up space.
For much of the history of the natural sciences people have contemplated the exact nature of matter. The idea that matter was built of discrete building blocks, the so-called particulate theory of matter, independently appeared in ancient Greece and ancient India among Buddhists, Hindus and Jains in 1st-millennium BC.[6] Ancient philosophers who proposed the particulate theory of matter include Kanada (c. 6th-century BC or after),[7] Leucippus (~490 BC) and Democritus (~470-380 BC).[8]
oh my,,, I didn't expect someone to actually reply. but thank you very much! its a big help.. i really thought I'll fail my class😭 and im sorry it took me a long time to tell my thanks to you, i was so busy. and i really appreciate your effort!! may all the good things come your way!!! xoxo
is milk heterogeneous?
Tysm for the video, very well explained😁
good
what year is for this
Im in the 6th grade but in america its for the 7th grade
Thank you for the helpful explanation. Subbed

Is a molecule made up of one type of atom?
No molecule is made up of two atoms
@@thebloosm4557 I know that. I asked one TYPE of atom?
@@stevegoody3744 Yes, only compounds are made of 2 or more /different/ types of atoms
Thank you by the way, kinda easier than a one hourd lecture, man I' definitely gonna fail my exam tomorrow
oh no!! good luck!!
I got this from my science class
Can a compound have more than 2 atoms in it???
Yes
yeh im still confused

IM IN GRADE 7 AND I UNDERSTAND
@Andrea Grace Chu lol im from asia too
@Andrea Grace Chu lol
Ohhh hello i am from Asia too and twelve year student, and I understand this easy because i knew chemistry college lessons as solubility, Lewis Diagram, organic chemistry, molecules, nobel gas configuration, moles and i have been studied the 118 elements of the Periodic table all by myself! And i got an iQ above 120 in chemistry.Ah also I know experiments and Theories (Aufbau principle & Thermal flow theory)... CalculationsAnd I forgot what else more
Im grade six and this is our exam so im really dead
oh no!! good luck!
