Single Displacement Reactions Part 1

[chumchum689]

thank you!

[animebaka14]

thank you for your videos!!! you saved my grades!

truthfully, i understood your videos better than my own chem teacher.

[goodmusic4lyfe]

Very good video but when you are doing the sodium + water. Doesn't hydrogen always have to go at the end of the equation?

[Jakobisisinamovie]

you're so awesome thank you so much. I was so confused until you did the part about the people dancing!

[yekoyewest]

Thanks Mr.P you really helped me out

[Kileeeification]

You are saving my chem grade, thank you soooo much.

[ALKCS2]

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

[Darkish04]

Do you have any videos which covers why H(OH) is written in that form because I am little bit confused on that, and is fluorine always written as a diatomic molecule when it is by itself?

But anyway, this video was great - thank you :D

[hypergiggles14]

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 :)

[downtownal400]

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 :/

[dbnice213]

On 6.40 . dont you need two nitrate to balance with Copper?

[CroRuption]

also isnt Cl a diatomic element? so it should have a number 2 with it?

[Papapodcasts]

@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)

[conanshinichi2010]

@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

[Papapodcasts]

@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.

[CroRuption]

how do you know whats more active?

[daleeps]

you make it so easy to understand! thank you :D

[Vahinemarangi]

Volume please!! This instruction is very helpful but the volume is too low. =)

[9579499348]

wnt tot download . bu how?

[CreateStatic]

OMG HIS VOLUME IS A MESS IN ALL HIS VIDEOS...CANT HEAR A THING!!

[lalalauren409]

you sound like 80% Jay Leno and 15% George Lopez and 5% Joey Vatone! lol

[xduhitssamx]

i wish this was louder..

[Papapodcasts]

@xduhitssamx Me too. I had a good microphone that broke down that afternoon when I recorded a bunch of these.

Mr.P

thanks.



[mauricedeltaco2]

Isn't copper more reactive than zinc? Zinc's got no business displacing copper. Right?

[Papapodcasts]

@mauricedeltaco2 According to the Activity series, Zinc is more reactive than copper.

[mauricedeltaco2]

@Papapodcasts But doesn't reactivity decrease across a period?

[Papapodcasts]

@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.

CHEMISTRY IS SO EASY MATH IS SO DAM HARD!!!!!!

[cjracer1000]

You sound like Jay Leno!

[smartnsweet0129]

I love your videos! They are really helpful thanks! :)

[Papapodcasts]

@smartnsweet0129 Thank you for watching. I'm glad I was able to help you. Best of luck with your studies.

Mr.P

[magepurexx13]

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?

[Papapodcasts]

@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

[essboarder23]

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?

[Papapodcasts]

@essboarder23 halogen plus a salt and a metal plus water.

[pikapower127]

Wow thank you very much!! your video really helped me understand !!!

thank you!!!!!

[yummygummy16]

i wish you were my chemistry teacher :)

[akosiarman15]

why in your first example you didnt put a subscript of 2 on Cl its diatomic elements right?

[Papapodcasts]

@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).

[killacall101]

thanks so much man... i had no idea but you explained everything so perfect that it just clicked..

keep it up and i plan on watching the rest of the videos!!

[stephanieceolin021]

i alwaaays save my life! thanks so much

[blondii7794]

is single displacement reactions the same as single replacement reactions?

[Papapodcasts]

Yes. Most chemistry books refer to them as either or.

[mdjk89]

@blondii7794 Yes diff books say diff there one in the same!

[steroids165]

i love you man!!! i finally get it but i quick question tho how do u noe if an element is diatomic

[Papapodcasts]

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.

[xxGuitarist1995xx]

Thank you, your pretty much the answer to my prayers, i have my finals this week and i couldnt understand any of this because i had an annoying kid who sat next to me and bugged me all class, and my chemistry teacher is horrible, thank you so much i might actually pass this because of these videos :)

[Papapodcasts]

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

[clonewolf4]

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?

[Papapodcasts]

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

[bomberfun1]

Thanks for the videos. What happened to the F2 that became just F at the very last example? Would it not be LiF2?

[Papapodcasts]

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.

[b4ustar18]

thank you so much!!! you rock!!! keep up the goooood work!

[Iz7zI]

You saved my life, those diatomics were hard for me I never knew you they can't be by themselves.

[MoeWoW0]

Thanks much, this helped a lot.

[Papapodcasts]

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.

[phsazn14]

Amazing teaching method, kudos to you, i find this very helpful to review my chemistry studies.

[kingofaust93]

this explains it great but the one thing i need to know now is, WHY!!. Why does this occur. my schools assignments asks us why this occurs and i cant find a website or book that tells me why?

[kmherpplrule]

wow which school is this?? ig ot the same assignemnt.....you go to mansfield state high??

[chemistrycoolguyscom]

why did you put CL 2 at the end of your chemical formula?

[Papapodcasts]

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,

[chemistrycoolguyscom]

i thought your greek but then i just didnt know for sure if you were greek and i got a message from you and i was shocked because i didnt know if you were greek , but how did you know am greek

[kmherpplrule]

can you tell me the websites you used to find this information for both part 1 and 2 plz....send it to my e-mail...

[nikkisacapilo]

thanks

[Papapodcasts]

You're very welcome thank you for watching. Good luck with your studies.
