5:21 sir i do have a little issue with the decomposition of CaCO3… i still do not seem understand why the Ca is being given an O and why not just CO3 instead of CO2
I’m a very slow learner sir so forgive me if this is already easy to understand, i just don’t seem to grab anything that deals with numbers easily 🤦🏿♂️
Hey Daniel, That is okay and is a good question actually. When we apply heat the bonds in CaCO3 are broken and the most stable products will be formed in order for this to be a favorable reaction. CO32- has a net negative charge without the Ca2+. Charged compounds such as Ca(2+) and CO3(2-) are unstable 'on their own' so would not be favorable products of decomposition. However, CO2 is a stable oxide of carbon (it is also more stable than carbon monoxide, CO which would be another possibility) which we know because it is so prevelant in the atmosphere. Calcium Oxide is also more stable than forming Ca2+ ions on their own. So the best combination of the products is CaO and CO2.
@@ChadsPrep oh i see, well now i understand, so i believe what you’re saying is no matter what compound there is and whatever reaction is been applied, the product has to be stable yes?
bro you are fr carrying my chem grade. some dude on csgo told me about you n u r a goat fr
Glad you found us, Nathan - Happy Studying!
Sounds like Chapter 4 is a banger! Can't wait. Thanks for these lessons.
You're welcome, Peyman!
I am NEET UG student from India and your video really help to me for better understanding of IOC.
Thank you sir.
You're welcome - Happy Studying!
This video was very informative. Thank you so much!
Glad it was helpful!
the easiest way I remember what subscripts to use is the crisis cross method!
Your boldness is inspiring me, and not only in chemistry 😉
Boldly go!
Thanks so much! Your channel is amazing! Will definitely share with others,
You're welcome, glad to hear it - and thank you!

And in 7:32 you didn’t seem to specify why the state of water in that combustion is in gamma(if im correct) and not in liquid state

For your second question that is an (l) in the parenthesis next to H2O, not a gamma sign :)

What about Neutralization Reactions, please? Were those not mentioned for a specific reason? Are they mentioned in a different video?
Neutralization reactions are discussed in this video - hope it helps! ua-cam.com/video/_XpsM24ybBw/v-deo.html
Thank you!!@@ChadsPrep
no problem... happy studying
Why aren’t the subscripts carried over to product side?
Do you mean for example Na + Cl2 --> 2NaCl?
I am not trying to correct you but isn’t the combination called synthesis
Which point in the video is this?
pls dont be to fast
You can slow down the video in settings if you like
really ? why that t-shirt?
Why not that t-shirt?😊
@@ChadsPreppersonally I love that tshirt
@@jeranimo.gaming And I love your comment!
