Love what you are doing here start your own business i love it every moment of these videos i learn more and i can still keep engaged this will change the education system one day
great video, i noticed a couple of things whitch i wasn't sure were correct, hopefully their helpfull: 1: i could be wrong but i'm fairly sure the romans never discovered how to make cement by heating lime and clay (they used a volcanic ash sand known as pozolana mixed with burnt lime which already existed as a building material, furthermore, it was the greeks which discovered this) 2: sand is an agrigate (not a big deal but it makes the cement+sand+agrigate=concrete look a little funny) i imagine the pozola source contained some extent of sand sized agrigate, however roman concrete normaly used an agregate akin to rubble (wikipedia describes it as being "layed rather than poured") without the use of additional sand. 3: lime light is actualy produced by the calcium oxide being heated (rather than as a result of the proces of decomposition of the carbonate) hence why the element is not rapidly consumed in the device of it's namesake. 4: the product "agricultural lime" is calcium carbonate (i could believe that some places use slaked lime to lower soil pH however i do not believe it to be the norm, as it is serverely caustic and significantly soluble in water, whereas the carbonate tends to leech less and has a pKb such that the pH is ameanable to most plants immediately after being applied)
Thanks so much got a limestone test tomorrow this helps so much
THANK YOU!!!!!!!!
Great video easy to understand and great animations 👍
A very good, academic video well suited for learning. Magnificent work. Thank you!
remember to speed the videos to 1.5 it goes faster and is still understandable
SO good and information
Thanks

Thanks Steve, I'm getting better at them (I have a team of lovely teenagers telling me how to improve them!). I'll post more when I've made them :-)
Very interesting, informative precise. Excellent
Thank you so much for this video
The illustrations helped too
Thanks for this!! Really useful for my chemistry test soon :D
This video was awesome. Thank you.

I like your channel icon.
Thank you 😊
:D
You're welcome.
Pls can you tell me how did you write chemical formulae (subscripts) in video scribe animation??
love this!!!
Thank you!
Can i use lime stone as a calcium carbonate?
rotary kiln for calcium carbonate: www.bestjawcrusher.com/products/rotary_kiln/?lyt
you forgot shoes! they use these as diving shoes in the bay
Thank you!
Thank you
Thk
thankyou
it is good for exams
Sodium and potassium carbonates are stable. These do not break down as shown in the video.
They do if the temperature is high enough
ME GUSTA! BWERRY NISHE
