[@alexisjonah8648]

Bro!!! I've been watching your little series of 11 videos, and they have helped me SOOOOO MUCH!!! Thank you for putting the experiments in your videos, they help so much!!!

[@stepbystepscience]

You are very welcome, and thank you so much for commenting.

I can’t explain how much of a lifesaver this guy is. The visual representation of the reaction is the cherry on top. 👌

I have been trying to do my chem hw for the past 3 hours with no luck until I found your channel and ALL OF YOUR CHEMICAL REACTION VIDEOS HAVE BEEN SO HELPFUL!!! I am not exaggerating when I say you have saved my life. I have a major test on Friday and your videos have covered everything I was having problems with! :) Thank you SO MUCH for taking the time to prepare such nice and detailed videos to ensure that students like myself are learning their chemistry :) I wish I had found your channel earlier on bc it would have saved me so much more time and energy.

Wow ! You have even shown the reactions . That is really appreciable .

[@stepbystepscience]

Thanks very much!

[@stepbystepscience]

@Madi Powell, that is because it is two KNO3s, not one KNO6. Otherwise 2 KNO3s would be K2N206.

Couple of questions.... 1.how can you tell when a compound is aqueous or a liquid? 2. Is every ionic compound with a diatomic element a gas? Great video and great explanation

[@stepbystepscience]

[@stepbystepscience]

Sebastian Cannon, I theory you could write it either way, H2O or HOH, either way it is water so by convention we write H2O. Otherwise you could write CaCl2 as CaClCl or ClClCa or ClCaCl…..Does that help?

[@jeckoh_9993]

on the last chemical equation you wrote CaOH2 + 2HCl===> CaCl2 + 2H(subscript)2(Subscript)O. When i wrote CaOH2 + 2HCl===> CaCl2 + 2HOH. Why did you do this as I am confused to your reasoning. thanks.

[@thatsohrobyn]

Hi, I have a question about the subscripts and hopefully I can word it the right way... What are you supposed to do with the subscript that was originally with an element when you bring it to the other side? For example in the first problem you put K with Nitrate which I understand, but I noticed that you didn't bring the 2 along. I thought it had something to do with BrINClHOF but K is not in there. Then in Problem 2 I see that the 2 was left behind but the 3 was kept. I am starting to see a pattern-- that maybe you only keep the subscripts for the anions? and only their identity from the table of common ions?-- but I wanted to clarify. Thank you very much in advance and sorry for the long question!

On the KI + Pb(NO3)2. When you solved the reaction why didn't you take the 3 multiplied by the 2? Because I thought it would've been KNO6 for the second compound. Would you please reply fast? I have a test tomorrow and this is so helpful

+Fabiola Osorio because Cr forms a -2 charge while Ag forms +1 charge. Using the crisscross method you get Ag2CrO4

Will you get a water product whenever there is an acid?

[@stepbystepscience]

Great question aj112598 Yes, I should have included one like that as one of my example….acid base neutralization is a type of double replacement reaction…acid + base = water + salt.

[@rhegieyudri]

Thank you so much for this, I can now explain it at class very well.

[@stepbystepscience]

Excellent, thanks for commenting.

[@keypoo513]

for the second problem you did, why did you leave the subscript 2 out when you balanced the equation and got KNO3 and not K(NO3)2?

[@stepbystepscience]

Because K has a charge of +1 and NO3 has a charge of -1. So one of each make it neutral overall.

[@diluwarhussain7534]

Thanks for giving this knowledge
