I want to thank the owner of this channel for his hard working. I learnt something from you , you're super Teacher and you're really helped us alot, i like when you're explaining the lesson in a coherent .
WOW, what a thorough and very clear explanation! THANK YOU!
This is a good video to watch, I think, even if having taken general chemistry. Plus I love hearing you. Hope all is well!!
Thanks for helping us with this video 🙏
i'm really greatful for ur job man :d
U saved my marks bro
Thanks 👍
Hi thank u
I understand that H2CO3 decomposes into H2O and CO2 because it’s more stable that way, but are there any other ions that have a similar situation? (Will decompose into something to be more stable?)
love from New york
Keep going
thank u!
Carry on bro
Thank u ✨🇧🇷
Thankyu
thank
How do I know that the educts are not CaCl2 and H2CO3? Ik co2 can dissociate In water but ..
Thxs😉
The product is acid or base?
How to solve this please Household ammonia, used as a window cleaner and for other cleaning purposes, is NH3(aq). The NH3 present in a 4.60-mL sample is neutralized by 35.36 mL of 1.029 M HCl(aq). The net ionic equation for the neutralization is
NH3(aq)+H+(aq)→NH+4(aq). What is the molarity of NH3 in the sample?
greetings from Turkey.
Love you from Pakistan ... Turkey is our second home
I believe in you
What if it's written by itself? CaCO3 ----> decomposition reaction
thank you sweet angel
Danko 🇧🇼
praise god 🙏
why is it that CaCO3 does not ionize and form Ca2+ and CO3-?
doesn’t it dissolve and ionize in HCl?
You're reacting solid CaCO3 with HCl. The solid is not going to exist as individual ions.
HCl is aqueous so H+ and Cl- already exists in the acid (hydrochloric acid is produced from dissolving hydrogen chloride gas in water).
@@DirigiblePlum thank you for the reply, i’ve already graduated 2 months ago from high school and going into university soon☺️
hey can anyone tell me why i can not directly write H2CO3
instead we write H2O + CO2
Because they both are different, H20 stands for water, CO2 stands for carbon dioxide, if u write them together, it will create a different compounds, H2CO3 is carbonic acid which is a different compounds (sorry if my english is weird, not a native speaker)
@@dododa6087 thanks! :)
@@alohaluvvs4251Sorry it's a year late, but I really need to correct the person above.
Carbon dioxide and water *does* form carbonic acid, they are wrong about that.
This reaction does produce H2CO3 (carbonic acid). The only thing is that carbonic acid is highly unstable in aqueous solution (due to presence of water) and will just decompose further into CO2 and H2O, which are more stable.
So it's actually a two step reaction, but we shorten it to what you see in the video because H2CO3(aq) just does not exist for very long at all.
Because carbonic acid is unstable compound thus why it dissociate to form water and carbon dioxide

why calcium cannot pair with hydrogen or carbonate, why it just fix with chlorine
Ca2+ so it is looking for something with a negative charge. Cl- supplies that in comparison to H. Ca is already bound to carbonate in the left side of the reaction so if it undergoes a rxn with HCl it will be looking for the negative anion from that molecule.
But why the H+ in HCl(aq) does not become H3O+ when we write the total ionic equation, it's in water!
now i am confused did you find an answer?
You're missing an important part which is the state. H+(aq) is generally understood to mean H3O+(aq).
H+(aq) is usually used in these types of equations simply because it's easier. You can use H3O+(aq) if you want, but it's pretty much overcomplicating things if it's really not necessary.
