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!!!
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.
Honestly from the bottom of my heart thank you for doing this. Your energy and teaching style is amazing. My teacher right now doesn't seem very happy with her work and isn't really teaching me anything. So thank you for your time and effort. :)
Thank you so much for this great video! I was very lost as to how to easily do a double replacement in class. This has completely clarified my confusion. Thank you again!
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?
Wish you were my ap chem teacher, I learn more in 10min through your videos than 45 minutes in class. Thank you for providing these videos, you helped me pass my chem final with flying colors!!
I have watched all of your videos dealing with chemical reactions and you explain them very well! Thank you for posting these videos on youtube, it has helped me practice to better my grade in chemistry! You are one amazing teacher!
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
this was SO helpful! thank you so much!! i could not understand the way my teacher was explaining it for the life of me. you're a true lifesaver! subbed for more helpful videos in the future :)
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.
+Royce Yuanchen Xu Yes the demos turned out well. Thanks for commenting. You can see a listing of all my videos at my website, www.stepbystepscience.com
I left school early when my teacher was going over this whole part of the segment and I still don't understand any of this. But its not your fault 😂 I'm just a slow learner but great video! It helped me a little.
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
My teacher just goes wayyyy to fast during the class period , which is only 50 or so minuets . Normally that alone wouldn't be an issue , but i was absent for 4 days due to my dog getting sick and dying . Thanks for helping me understand my homework in the class when my actual teacher doesn't have the time to :)
Thanks for actually replying , most people with popular channels never do . And also , thanks about my dog . Trying not to be too sad about it , she got really sick and was suffering so my family decided to put her down . Yea its really sad and it sucks that it happened at all , but I'm glad she isn't suffering anymore , shes in a better place now . I appreciate you making these videos , and I appreciate the legitimate care and interest you show in your viewers . Thanks .
I'm kind of confused. AgNO3+k2CrO4------> AgCrO4 + KNO3 (have not put in subscripts I get that K has a charge of +1 and NO3 is -1, but since k2 wouldn't it be +2? Or do we not count the 2??
Loan Le If you are referring to the products then it is KNO3. K is +1 and NO3 is -1. The K2 from the reactants will be taken care of when you balance the equation.
Question, during the AgNO3 + K2CrO4 reaction, when Ag separates from the NO3, does it take back the electron it had donated to the NO3? Or does it leave as Ag+ ion?
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.
How do you know that iodine is -1 and something else is plus 2? I apologize, I've never had any formal chemistry training. But I'm trying to study it on my own to get ready for an introductory chemistry class.
+Derek R Iodine is on the right side of the periodic table; these are the non metals. They gain electrons to fill their outer shells and therefore have a negative charge. On the left side of the periodic table are the metals. They lose electrons to get a full outer shell and therefore have a positive charge.
I'm a Filipino so sorry if my grammar is incorrect or something haha. I've been watching some of your vids and every single one really helps me so thank you so much :)
Erin Eubanks Because K is +1 and NO3 is -1 and therefore you need one of each. In the first case K is +1 and CrO4 is -2, therefore it takes 2 K to satisfy one CrO4.
At 10:30 isn't it a neutralization reaction because Ca(OH)2 is a base and HCI is an acid, right? Though I'm not sure. Apart from my question, this video was very helpful and informative.
I don't understand the second and last question, when combining K with (NO3)2 wouldn't the balanced equation be K2(NO3)2? because there are 2 No3 atoms? and putting a 2 infront of the K would mean there are 2 K and 4 No3? therefore it would be unbalanced, same with the 4th question?
Dane Tiffin Good question but no, when making the products you always start with the single ions. K has a charge of +1 and NO3 has a charge of -1. So it takes one of each to make a neutral compound.

Thanks for the great comment
just wanna say thank you so much! i was out sick for a week and therefore have to learn all this stuff on my own and your videos helped me a lot!!
I don't even know why I have to go to school I learn more off of RUclips
AvidChildHere I know what you mean, thanks for the comment.
i agree
Saaaaame 😭
this didn’t age well
You are a great teacher! I love that you showed us the reactions. EXTREMELY helpful video!
Thanks for the comment...You can see a listing of al my videos at www.stepbystepscience.com
Fabiola Osorio, the CrO4 has a negative 2 charge and the Ag has a positive 1 charge, there for it takes 2 silvers to satisfy the chromate.
Step-by-Step Science therefore
But how do you know CrO4 has a negative 2 charge?
Osvaldo Flores it’s a polyatomic ion, and it’s a special case, I think
This man pinned a comment from a week ago on a 7 year old video... Respect.
Thanks for commenting
Better than my teacher.

thats rude
Nirshanth Sivalingam My teacher did a horrible job explaining it and I literally looked at it like a foreign language. this helped alot
I'm doing online Chemistry 2 with no teacher (self paced) and this video seriously helped me understand this topic. Thank you!
That's great to hear, you're very welcome!
Thank you so much for this great video! I was very lost as to how to easily do a double replacement in class. This has completely clarified my confusion. Thank you again!
Thank you so much. I've been failing chem, and my teacher does not explain in a way like this. It makes sense now.
Kaitlin McKenzie Great, I always just try to go step by step. Thanks for the positive comment.

Thank you.
@@stepbystepscience No, thank you. you helped me alot to pass through chemistry class. Thank you so much.
@Madi Powell, that is because it is two KNO3s, not one KNO6. Otherwise 2 KNO3s would be K2N206.
I have watched all of your videos dealing with chemical reactions and you explain them very well! Thank you for posting these videos on youtube, it has helped me practice to better my grade in chemistry! You are one amazing teacher!
Way better than my teacher, thank you so much, Great teacher!!!
Sir,this video helped me a lot to understand double displacement reaction and I hope many other students will also be benefited.
Love u Sir.
It's my pleasure and thanks for the great comment.
Sir, you are an incredible teacher. thank you for your contribution to the humankind
You are very welcome and thanks for the very nice comment.
Best chemistry explanation out there....so clear and actually doing the experiments sets you apart from all the others! Plz keep it up!
These videos are helping me a ton! I have a test tomorrow and almost no one in my class knows how to do it. These videos help me so much! Thank you!

1. Not sure what you are asking but, the solubilit y table may be helpful.
2. I would have to say no.
May you be blessed ! Thank you much for helping me with my homework.
Happy to help!
Wow ! You have even shown the reactions . That is really appreciable .
Thanks very much!

extremely good, i had a bad confusion before regarding this type of reaction
Glad it helped clear up your confusion.
Thank you I have an exam tomorrow and know it's much easier than my teacher explained it.
Liked.
I wish you lots of success on the exam, thank you for commenting.
THANK YOU, i was so confused about this in class yesterday!
helpful but you go really fast .... love that you do the experiment too... we dont do this enough in school. Thank you for your video
acid base neutralization is a double replacement reaction

Thank you for this video this really helped me a lot
You are very welcome, thanks for your comment.
Woah ! Thanks for showing the reaction.
Thanks for commenting, the reactions are cool!
do we do addition to the elements who have diffrent charges everytime? and how to know which one we should do addition
Question, during the AgNO3 + K2CrO4 reaction, when Ag separates from the NO3, does it take back the electron it had donated to the NO3? Or does it leave as Ag+ ion?
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?
Because K has a charge of +1 and NO3 has a charge of -1. So one of each make it neutral overall.
Will you get a water product whenever there is an acid?
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.

If when I make a new combination, the subscripts are both 2, can I cancel them out?

Hello! On the first equation, why did the '2' subscript on potassium get dropped when it became potassium nitrate? Thank you!
Erin Eubanks Because K is +1 and NO3 is -1 and therefore you need one of each. In the first case K is +1 and CrO4 is -2, therefore it takes 2 K to satisfy one CrO4.
At 10:30 isn't it a neutralization reaction because Ca(OH)2 is a base and HCI is an acid, right? Though I'm not sure. Apart from my question, this video was very helpful and informative.

Dane Tiffin Good question but no, when making the products you always start with the single ions. K has a charge of +1 and NO3 has a charge of -1. So it takes one of each to make a neutral compound.
