Predicting Products of Single Replacement Reactions

[@artisticbeing260]

Remind me why we're all finding necessary to learn this in the first place? It's not like we're gonna use in 10 years...I swear. Teachers make such a big deal out of these kind of things. But you make chemistry look so easy.

@@calebmatheson3857 Ohhh woww I haen't thought about that. An now, I totally agree!! I also thought about why we are learning this, and I come to realize that it really helps us to teach self discipline and enhance our desire to learn new things.

[@jennifercarmona9788]

also, for single replacements I learned as A+BC=B+AC in order to predict your prodicts

[@TommyTheCat1313]

Hi Ms. Maribel! First of all thank you so much!! Secondly, how would you do a single replacement equation if one of the metals on the activity series and the question is a transition metal and you don't know it's typical charge?

[@sukhmanaulakh21]

Transition metals are on the activity series so if you are given the activity series you will be able to predict the products. To add, if you don't have the activity series for a test or something like that your teacher is pretty evil.

[@vijayfn6936]

Thank you so much. This helped me a lot!

[@iqrakharal7504]

Great video! I just had a quick question...when we're doing the innie and outie part you said to ignore the subscripts. Is it safe to assume you only ignore the subscripts outside parentheses? So, whenever you're predicting the products, the subscripts inside the parentheses will be carried over to the products side?

[@sukhmanaulakh21]

Yes, for polyatomic ions (the ones with parenthesis) the subscripts inside the bracket will carry over to the other side. Good question and hopefully this answered it.

Hey Melisa u are awesome..... But please make a video on predicting products of decomposition reactions as soon as possible:-))

Hi Melissa! I was wondering if there was a place we can get the activity of metals chart that you used?

[@Soctimely]

Google online for the reactivity series There are really nice mnemonics to remember th order 😊

[@science-y9209]

hello melissa .. it was an awesome video and thanks a lot for your great help.. i wanna ask one question: when potassium is more reactive than lithium then why is it on the top of the reactivity series..? please do tell me if i have my fact wrong..😊

[@savannapierceshimomura]

Does anyone know why there is no reaction when it is lower on the activity series! I loved the video very helpful! 🕺🏻💃🏻😤

Why, in the activity series of metals, would magnesium be higher than iron? Is it the charges or something?

[@andrewmagana8093]

how do you find out the activity series of metals if you don't have a chart like the one on screen. can you find this out by just looking at the periodic table?

[@azurecerulean1279]

Is there a reason to why we put Fe first in the product instead of it being MgO + Fe?

[@memegalore257]

Good Job, Melissa👍

[@melissamaribel]

Thank you 😊😁

I have a question- In the first example's product, should we write Fe or MgO first? Or it doesnt matter?

So when you balance the reaction you just switch the two coefficients right?

[@jamesfreitag7275]

You pointed out the obvious stuff but what about if one of the metals is not on that chart? Then what happens?

Thank you very much for your educaive videos... i salute you .... one question please : if we put a zinc rod in aqueous solution that contains zn(2+) cation , how would i use the reactivity table in this case ? . thank you .

[@melissamaribel]

You're welcome Mohamad, to answer your question, the reactivity table doesn't apply to this specific example since they are the same element for it to apply the elements must be different and be a single replacement reaction.

[@mohfa1806]

Chemistry with Melissa Maribel Thank you very much for your fast reply...i really appreciate it ... your answer directs me to another question please : why in galvanic half cell and when a zinc rod is put in znso4 (aq) the solid zinc atoms looses two electrons and ionizes into the solution as zn2+ ? , (this happens even before we connect the zinc rod to the cupper rod in the othe half) !. Does this happens due to reactivity table rules ?...Thank you

[@melissamaribel]

@@mohfa1806 The reactivity table is used to see if a reaction occurs or not, yes we can see that a reaction will occur between zinc and copper since it goes from the higher metal Zn to the lower metal Cu. But that's all the reactivity table would be used for in this given case. In case you need more help with galvanic cells I went over that here: kzbin.info/www/bejne/onOTeZd4o66Nf8k I also recommend another youtuber's video, he does a great job explaining this too: kzbin.info/www/bejne/bZOWZYuPnKZ3oq8

[@mirai23]

i love your videos aesthetic! thanks for the help, u are a savior

[@dv4346]

what about for C2H6 + O2? I didn't see that on the Activity Series! Will oxygen replace Hydrogen?

[@melissamaribel]

This is because this is a different type of chemical equation. That example is a combustion reaction which results in your products always being CO2 and H2O. I recommend watching this video ➡️kzbin.info/www/bejne/sGGUaWqcbcyknLc

[@baileyelliott96]

Where can I get that chart???

[@crod1232]

How do you know which is the first metal? I understand left to right but why couldn’t it be written the other way around? I did a lab where we reacted different things and I have to write equations but I don’t know what order?

[@crod1232]

Also, how do you predict reactions when it’s non- metals? Ex. NaCl + I?

[@melissamaribel]

Yes it is the whole idea of left to right, if the first example of Mg + Fe2O3 were written as Fe2O3 + Mg it would be no reaction since we are now going from Fe to Mg and the rule is a lower metal to a higher metal is no reaction. So the order does matter. Did you have the question you did in lab? It would be easier to explain the question.

[@melissamaribel]

This is similar except we do not have to worry about no reaction forming since that is just for metals. For this example the Na would combine with I to form NaI as one of our products and the second product would be the Cl, now beware it wouldn't be just one Cl because Cl is a diatomic molecule meaning it exists in pairs so it would be Cl2. Our two products are then NaI and Cl2

[@crod1232]

So for this lab we are reacting different metals and non metals to rank them in order of reactivity (by observing a change) For testing metals we took a sample of metal and added salt solutions. For example I took some pieces of zinc and added CuCl2 solution. When I write this equation how will I know if It should be “Zn + CuCl2” or “CuCl2 + Zn”? As for non-metals, we did the same thing. My teacher used “NaCl + I2”as an example for a case where no reaction occurs. I am confused should I be stating “no rxn” or is it “NaI + Cl2”? Visibly we saw no change so how could it be NaI + Cl2?

[@azurecerulean1279]

doesn't a list for non metals exist too? Florine Chlorine Bromine Iodine

Hey...... Is Replacement reaction is that displacement reaction ?

I think you talking about a single replacement reaction. Replacement reaction and displacement reaction is the same thing. We call this "Single replacement".
