i always come to your videos to learn how to do the things we are learning in chemistry because my chem teacher doesnt know what hes doing. this has helped me out a lot. thanks!(:
THANK YOU SO MUCH MR.P! HELPED ME COMPLETE MY HOMEWORK, HAD A STRUGGLE WITH SINGLE DISPLACEMENT REACTIONS AND AFTER WATCHING THIS VIDEO I UNDERSTAND IT! THE DANCING EXAMPLE HELPED ALOT! HAHAHA :) thanks
OUTSTANDING vid!! Very good examples, explained clearly, in an easy-to-understand way, WHENEVER I COULD HEAR YOU. I have to make a note to myself to turn down comp speakers after your lectures so as not to blow em out when I switch to music :/
Thank you SO MUCH for putting this up! I missed several lessons in my chemistry class because I was sick and this helped me understand what I missed :)
How do I know whether the metal will diplace the other metal? Do I look at the electron structure? What I mean to say is, why does Zn displace Cu in CuNO3?
Thanks for watching. Li and F would make an ionic compound, and according to the cross over rule, Li is +1 and F is -1. Those charges cross over to give you a formula of LiF. Only when F is on its own is it F2. However if it was combined with any Group 2 element such as Ca, then you would get a formula of CaF2, The 2 in this example has nothing to do with the fact that it started off as F2. I hope this helped, best of luck with your studies. Mr.P
@akosiarman15 Cl is a diatomic when it is an individual molecule. Cl is combined with K or with Na, therefore it is paired up with a metal (it's not diatomic when paired with a metal).
@magepurexx13 You can write water either way. The HOH is really just to help simplify balancing. Yes you do have 2 H's BUT when writing it as HOH you are treating the first H as a metal and the OH as the non-metal polyatomic. So in a single replacement Na + HOH, Na would replace the first H, which we said we'd consider it as a metal. So therefore, Na + HOH --> NaOH + H2. Hope that shed some light. Thanks for the sub. Best of luck with your studies. Mr.P
Thank you for the kind words. Always continue to ask questions when uncertain. That will be the difference between a good mark and a great mark. Thanks for watching.
Thanks for watching. Yes we are creating a molecule but we are creating an ionic molecule. Ionic molecules require the crossover rule. Also keep in mind that even through you originally have 2 atoms of H on one side and 3 on the other, this is where you have to start balancing your equation. The number of atoms between side can be different but the coefficient (number in front) can change to balance the number of atoms. Let me know if it helped you. Best of luck with your studies. Mr.P
@conanshinichi2010 The 2 stays with the F2 since it's diatomic. However, when it combines with another atom it is not considered diatomic anymore. It is diatomic when it is by itself.
@mauricedeltaco2 Not necessarily. Fluorine is a very reactive non-metal and it's across the periodic table. Stick to the Activity Series because there are so many more to consider than just typical reactivity. That's why we use an Activity series for such questions because merely looking at the periodic table alone does not give us all that information instantly. Mr.P
Diatomic are atoms that are paired up with one another. They cannot exist as an individual atom without being paired up with itself. Example, hydrogen, will never be written as H. If it is by itself it has to be paired with another H as such H2. There are 7 diatomics: H, O, N, Br, I, F and Cl. All of these, whenever they are BY THEMSELVES are diatomic. Think of the follow phrase: In Floride, Brad Never Cleans His Oranges. Note the capital letters. Thanks for watching. Mr.P
Yiasou ti kanis, the reason the formula says Cl2 is because Chloride is considered one of the Diatomic molecules. Which means that Cl doesn't exist in this formula alone but bond to another Cl. Cl-Cl [Cl2] Thanks for watching. Kali nixta, Mixhali
I am confused about diatomic elements. I know as much as that when they exist individually in nature, that they are double, but when you did the displacement reaction in this slide, aren't you "creating" molecules when you do this? Because, first you have Na + H(OH). Then, when they switch, you have H2 Na(OH), where in the product side there are three hydrogens instead of two. Does this work? One more question, are the ions of the diatomic elements (ex. hydride, iodide & flouride) double also?
I have a question It says a Metal+ salt is a type of single displacement reaction. But it's asking for 2 other types of single displacement reactions/example?
@CroRuption Cl is diatomic when it is by itself. At 3:30 it is ALWAYS paired up with some metal so it is NOT diatomic. Please review my video on writing formulas. You are missing some of the valuable basics you need before doing these questions. Notice at 8:35, THAT'S when Cl is diatomic (in the products = right of the arrow)
these are great! but what if we had to write them in net ionic equations? wouldn't the first example (K+ NaCl --> KCl + Na) end up being Na^+1 --> Na^0 and therefore not be a reaction? Confused! :(
i always come to your videos to learn how to do the things we are learning in chemistry because my chem teacher doesnt know what hes doing. this has helped me out a lot. thanks!(:
thank you for your videos!!! you saved my grades!
truthfully, i understood your videos better than my own chem teacher.

This video taught me more than my own chemistry teacher taught me in two weeks. You're really, really, REALLY good at explaining this.
you're so awesome thank you so much. I was so confused until you did the part about the people dancing!
You're very welcome thank you for watching. Good luck with your studies.
Mr.P

You saved my life, those diatomics were hard for me I never knew you they can't be by themselves.
Thank you SO MUCH for putting this up! I missed several lessons in my chemistry class because I was sick and this helped me understand what I missed :)
@smartnsweet0129 Thank you for watching. I'm glad I was able to help you. Best of luck with your studies.
Mr.P
Thankyou so much for uploading this, I finally understand this. Man, my teacher does not know how to teach.
I really appreciate your videos, i was failing in science but then i wached ur videos and now im an A-
How do I know whether the metal will diplace the other metal? Do I look at the electron structure? What I mean to say is, why does Zn displace Cu in CuNO3?
Fuck him

Awww...thank you for that. Best of luck with your studies.
Mr.P
I love your videos! They are really helpful thanks! :)
you make it so easy to understand! thank you :D

You are a great teacher. Thank you!
You are very welcome. Thank you for watching. I wish you best of luck on your finals this week. Let me know how they go.
Mr.P
if you know anything about trig and calculus u should make videos bc u are a very good teacher

Yes. Most chemistry books refer to them as either or.
@mauricedeltaco2 According to the Activity series, Zinc is more reactive than copper.

i love you man!!! i finally get it but i quick question tho how do u noe if an element is diatomic
@Papapodcasts where did the 2 in the F2 went i thought it has to have a subscript of 2 because its diatomic. im quite confuse. thanks
dude...you're awesome....

Very good video but when you are doing the sodium + water. Doesn't hydrogen always have to go at the end of the equation?
Why can you write H20 as HOH and do u have 2? If not, then how would you try to use single replacement with Na+H20?
I have a question
It says a Metal+ salt is a type of single displacement reaction.
But it's asking for 2 other types of single displacement reactions/example?

also isnt Cl a diatomic element? so it should have a number 2 with it?
i alwaaays save my life! thanks so much
@xduhitssamx Me too. I had a good microphone that broke down that afternoon when I recorded a bunch of these.
Mr.P
these are great! but what if we had to write them in net ionic equations? wouldn't the first example (K+ NaCl --> KCl + Na) end up being Na^+1 --> Na^0 and therefore not be a reaction? Confused! :(
You. I love you. THANK YOU!
You just made my entire day. XD
thank you!
how do you know whats more active?
@essboarder23 halogen plus a salt and a metal plus water.
you sound like 80% Jay Leno and 15% George Lopez and 5% Joey Vatone! lol
wnt tot download . bu how?
thanks
2:30 Mr. Steal Ya Girl.
LMFAO MY TEACHER HAS THE EXACT SAME NOTES AS YOU
You sound like Jay Leno!
the volume is incredibly low
@blondii7794 Yes diff books say diff there one in the same!
you should upload your videos at over ten minutes long so that you can put in ads to your videos
yes
Can you speak in a louder voice .I can't hear a single word of your's though the video was good :)
i wish this was louder..
I hope this will work to meeeow! :))
CHEMISTRY IS SO EASY MATH IS SO DAM HARD!!!!!!
Can you come replace my science teacher? Pretty please?
OMG HIS VOLUME IS A MESS IN ALL HIS VIDEOS...CANT HEAR A THING!!
thanks.
