Stoichiometry Made Easy: Stoichiometry Tutorial Part 1
HTML-код
- Опубликовано: 13 окт 2024
- This is a whiteboard animation tutorial of how to solve simple Stoichiometry problems. Stoichiometry ('stoichion' means element, 'metron' means measure) is a method of converting from amounts of one chemical in a chemical reaction to amounts of another chemical in the same chemical reaction. Stoichiometry is a lot like determining the amounts of ingredients needed in cooking. This is my first tutorial in the series.

Remember:
1) only moles of one chemical can be converted to moles of another chemical
2) the balanced chemical equation is your conversion factor
3) write down the units and chemicals as you go
My goal is to make chemistry easier ;)

Sorry, but when you start just throwing numbers in front of your NH2 (or NH3) and your 3H2.... it looks like you're just pulling numbers out of your butt. Is there some logic you're following?
Yes, there is some logic...it's called balancing chemical reactions/equations. This video is not intended to teach balancing, so you should look up a separate video on that. Balancing is a more basic chemistry skill that must be learned prior to stoichiometry. However, this video does explain how this reaction is balanced. You need the number of each element to be the same on both sides of the equation. The number of an element can be calculated by multiplying the coefficient (big number in front) by the subscript. Only coefficients can be changed when balancing.
The 2 in front of NH3 is put there because there are two nitrogen atoms on the left in N2, so you need two nitrogen atoms on the right in 2NH3. That now means you have six (2 x 3) hydrogen atoms on the right, so you also need to put a 3 in front of H2 to get six hydrogen atoms on both sides.
Try the following simulation to help yourself learn how to balance a reaction.:

Thank you! I'll check that out. Owe you one!
No problem!
Deez nuts ( ͡° ͜ʖ ͡°)
I think im just unteachable

me too, but we can do this if we continue to try. When you were little you probably got frustrated when trying to learn how to read (I know I did and I'd cry thinking I was stupid) but here you are now, being able to read. It just takes persistence. I don't understand stoichometry either.
You just need to find another video that explains it in the way you understand

Stoichiometry was a struggle for me in General Chemistry but this helped me out big time. The stoichiometry word problems were always a real pain in the ass though as I didn't know how to approach them but now I do.
glad it helped :)
4 years later you absolutely save my ass on a test you are a hero young man
this 7 min video taught me more than what my chem teacher taught me in an hour
Same to me
Only if u listened to him😕
Cutie
lmao guess what our science teacher is not even bothering us to teach and gives us tons of questions each week then gives us a video link to "learn", this is so dumb
@@mertturgut4017 feels bad; Can relate
Thank you for this. I think some professors know stoichs so well that they glaze over very fundamental key points that make it make sense to someone who's never even heard of it before. This helped me big time.
Holaa Jesus is coming back soon! I’m telling you, only 1 name gives life: JESUS! 2 or 3 years ago i was depressed and suicidal and one day when on tiktok I encountered the love of JESUS. The Unconditional saving love of Jesus. You see, we are all sinners, the Bible says it, in “Rom 8;28: For all have sinned amd fallen short of the glory of God” we have all at some point in our life turned away from God, but god does not want us to be separate from him. You, God is holy and a righteous person who lives in heaven and made all and most imporgantly cares for all.("1Peter: Cast all your cares upon Him, for He (God) cares for you" have strayed form Him into the devils trap of temptation to sin, which we will all one day be judged for . I beg you, please turn away from sin, becaue it will send your soul to hell. So , you see the result of sin is death and eternal separation form the goodness of God, which is a terrible matter, because this leaves us with the fire and wrath of hellfire. Thats why Jesus died. The only son of the living God ,Jesus Christ loved you enough to give His life for you, so that instead of dying, you would be saved and obtain a place in Heaven, not by your good works, but by the works of christ himself. (Jn 3 :16 For God so loved the worñd tjat He gave His One and Only begotten Son, tnat whomsoever believeth in Him shall not perish but have everlasting life") . This is applicable only if you repent of your sins!, which i beg you to do.
not knowing how to cook grilled cheese is that saddest thing I've ever heard in awhile
when you're raised vegan and you start eating cheese... when i told you i was LOST
My ninth grade science teacher had to explain water was NOT a element to half the class..
Wow ! u explained this whole thing so smoothly that now i am
Feeling to make a grilled cheese sandwich for myself
Only person who’s gonna help me not fail Chemistry thank you so much
who in their right mind puts one piece of cheese on a grilled cheese

Very nice video, I’ve been struggling a bit in class to follow and understand. But this does really help. Thank you
You are literally doing my Chemistry teacher's work since we having a quiz tomorrow and she told us to watch a video at home smh...
Very helpful, thanks a lot teach!
I had issues with this in high school and now my son is having issues. Thanks for breaking it down! Over 25 yrs later I understand it again bc of your easy to follow video!
Please make more videos; they're so helpful! Thank you so much for the good work you do :)
You're welcome! I will make more, but it is going to take some time.
You’re the only person who’s gonna help me not fail Chemistry.. super straight forward and helpful
did you fail
You pass?

This is very helpful, thank you. The food comparison really helps.
This was so comprehensive and thorough. I really appreciated you making this video.
i have been struggling to understand this for two weeks now and it only six minutes of your video to understand what i have been bawling over every class. thank you so so much for this i really appreciate your work
Thank you so much. I was so confused from my chem class on why we converted to moles and now it makes so much more sense to me!

thanks alot!! I have been struggling with stoichiometry problems since a long time and they had become a complete mess for me... you actually taught me how easy they can be to work with using that 'sandwich' example.
glad to help!
Thank you very much unfortunately I only saw this video after taking my stoichiometry test which I think I didn't do too good in but I seem to understand this more
Man, you did this beautifully. Thank you. Awesome Job.
When you don't know how many slices of bread you need to make 7 grilled cheese sandwiches in your head, you know you're in trouble
I love that the man and his friend are super high in this chemistry tutorial.
you know, it's chemistry ;)
I understand everything!Thanks a lot and please continue
making it easy for us!
you're welcome!
ILYSM you don't understand how helpful this is.
you actually also need butter to make grilled cheese
To make good grilled cheese, you are correct. ;)
ahhh yes "good" grilled cheese is a good way to put it
Dead 😂
I have watched so many videos now completely confused. Not a single one made any sense to me. When I watched this one, however, it just….CLICKED. THANK YOU SO MUCH.
Im in college and this video just helped me so much! thank you!!
You were able to makes everything so understandable. Thank you!
Thank you! I wish your pillow will be cool forever! This taught me more than my chem teacher teached in a whole semester.
Incredible, creative, simple and well articulated. Thank you so much!!
Thanks so much. This gave me a clarification. I love the analogy between the sandwich and chemical reactions. It help me understand as someone who finds symbols complex lol
thank you. this is the ONLY video that made sense to get the initial confusion out of the way. the concept of mols is confusing at first.
glad it helped :)
I'm so glad my teacher shared this video with me. The sandwich example was very helpful!
Glad it was helpful!
This is really helpful but have to watch it 2 times with full concentration 🤯Thank you very much
Thank you for your nice explanation.
Your channel just becomes my favorite channel on RUclips
thanks for the video i was feeling stoichiometry difficult but after watching this it helped me alot
glad I could help :)
This helped me tremendously thank you kind sir
THS GUY DESERVES ALL THE HAPPINESS IN THE WORLD!!!!!!!!!!!!!!! THANK YOU SO MUCH!!!!!!
bro thank you so much you saved my grade fr
Ha, i love how its applied to food!😆
thanks man you've helped me alot :) now i know the basics of stoichiometry.
GOD BLESS YOU I WAS GETTING READY TO HAVE A BREAKDOWN IN THE MIDDLE OF CLASS 😭😭😭
this 7 min video taught me more than my 1hour lecture in class
thank you so much, ive seen so many videos and this one for sure made it way easier to understand how to do the calculations!
Yeah it made me understand stoichiometry better ❤️❤️ you're great 😊❤️
I jumped in joy when I got the answers right!😩 Thank you very much.
You have literally saved my sons chemistry grade thank you
glad to hear that!
Love it! Well explained... Thank you Sir
Stoichiometry is scientist's way of measuring the elements and other chemicals in a chemical reaction. 00115
Omg, thank you! It finally makes sense! Now, I have to go help my teenager.
Wow, this is actually super easy! Thank youu
I love the way you teach by making the concepts easy. Is it possible to teach to calculate the PH without using the calculator? I would really appreciate.
Well if you know the equation for -log then I’m sure you can
thank you brother, I'm going to be a renowned engineer with this video
ID: 00404 Chemistry is like cooking because there is a constant ratio that was being followed. When we needed to find out how much of one element was needed in the equation, we referred back to the grilled cheese problem and used the same idea. Along with this, the balanced equation acted as a recipe that allowed us to figure our the required amount of element.
In chemistry, various chemical reactions are able to tell people the ratio of elements needed in order to make a specific reaction occur. Cooking is highly similar to this because recipes also require certain ratios of ingredients to prepare a final dish.

You are great man. Congratulations 👏
This is an amazing video to teach the concept !

I LIKE HOW YOU ILLUSTRATED GRILLED CHEESE INTO A STOICHIOMETRY FORMULA. I FINALLY UNDERSTOOD IT THANKS A LOT :)))
Dude thank you theres covid right now and ive been sleping through my chem class and I have a unit test tomorrow. this vid really helped me
the sandwich thing really helped, thanks
Glad it helped!
I’m studying for my praxis and this really broke it down for me to understand!
Thank you so much for your video. I finally understand it in a simple way. I speak Spanish but I also use this videos to improve my technical English. Greetings ❤️.
omg thank you so much like fr, i don't even comment on youtube videos but this omg helped me understand so much
thank you!!
I had this high school chemistry teacher who tried to intimidate us and would fail anyone who didn't know 100% of the material. Like if you didn't get an A+ on every quiz, you were kicked out of the class and given an F. This gave me a ton of anxiety, so of course I failed and got kicked out. Now I'm taking chemistry again and trying to overcome my trauma
Go you!🌷🪼🍡
man i love this guy’s voice.. also this is very helpful
im not really good at math and stoichiometry is very confusing but i feel like this vid helped me, Thank you so much
Perfectly explained. Thank you so much
Who here actually understands this???!! I did by watching! Thank you!!!!
A great refresher. Thank you!
An interesting thing about stoichiometry is not all compounds are stoichiometric. Oxides and sulfides of most metals are non-stochiometric. To a rough.approximation they seen to be stiochiometric. However they don't obey the law of definite proportions exactly. Oddly these compounds were where the idea of stoichiometry came from.
For instance ferrous sulfide is supposed to be FeS. It is more like Fe.95S to FeS.95. The early chemists did not have equipment accurate enough to notice these differences.i
Amazing! So clear. Thanks for making it fun. Also I feel like the grilled cheese guy at the beginning had the munchies lol. Thats a lot of sandwiches
Thank You thank you thank you. This video really helped me. Tomorrow I will be writing the physics test. Thank you so much
I have an exam tmrw this is a lifesaver ty
Totally subscribed. You are so helpful sir!😃
chemistry is like cooking because the ratio of the recipe mimics the reaction and its balanced equations. when you're trying to solve a reaction you measure out the element of the recipe like you would the reactants in the balanced equation, 00418
you want a comment? how about this, I'm in the shower wanting a grilled cheese sandwich now. I demand grilled cheeses on Friday. ya know, to practice or whatever.
guess whooooo
RO
Stoichiomertry is the relationship between the substances that are taking part in a reaction/forming a compound typically a ratio of whole intergers, 984311
That's stoichiometry* not stoichiomertry
I think you just helped me pass chemistry.
Wow this has helped, I like the illustrations I think it's what made understand better. Thumbs up 👍👍
This really helped me understand, thank you!
you're welcome!
Your really helped me
Chemical reaction is like a recipe because the reactants are like the ingredients, and the products is like finished meal. Also in a recipe you need a certain amount of ingredients to make a certain meal, just like how a chemical reaction needs a certain amount of reactants to make a certain product.

thank you so much! i hope you could make more videos, this really helps me while reviewing for my college entrance tests
I'll be making some more this summer...don't know if it will be in time for you, but what specifically do you think I should make a video on?
i hope u could add more chemistry topics and physics, i know a lot of students (including me) has been looking for videos that could help us specially in that subjects T/T
already made some playlist for your videos and save it tho, really helps me a lot
Easy to understand, thank you!
you're welcome!
U know ur teaching is awesome 😃 the concept on which i wasted almost my whole gb on has payed off i understood whats stoichionmetry calculation😍😍😍😍
Amazing video! Taught very well keep it up 😊👏
Hey man thats more easy to find.....than our teacher told us🇮🇳😍🇮🇳
Thank youuuu chemistry Jesus
This video is a life saver
Awesome stuff...this video helped perfectly 🙌🏾👌🏽
Thank you
