bro lemme know real quick if you can do my research investigation. scientific question is does temperature and concentration have an effect of the rate of reaction (sodium thiosulphate and hydrochloric acid)
BEJÖTT EGY PETKÁNY, MARI!
Mi a szar az a vállán?! 😂😂😂😂
she is a peng ting
wth is on her shoulder
Take a chemical experiment that looks like magic, make it as boring and tedious as possible, and Voila! – you've put kids off science for life. Good work.
In the Table, instead of H2O, isn't it supposed to be HCl?
I have a question about this class. What is on her shoulder?
Who can tell me how to calculate the concentration?? (4th column)
In this what is the color of sulphur
Maja nahi Aya
Thanks a lot from egypt
thanks, for this video very useful.
Hi. What kind of errors can occur here, when doing different kind of reactions.
Ugh here to learn something but that thing ohln her shoulder ruined it hahahaha WHY? And WHAT is that? Hahaha
hey its kyanada
She kinda looks like carol from the walking dead.
is it possible to look at both concentration and temperature at the same time.
I hate science so I hate you
Half of the people in this chemistry video talk about a prop on her shoulders.
1 mole on d lady's shoulder
She has a mole on her shoulder (chemistry genius)
This is a blank comment experiment😶😅😂
Sodium thiosulfate +hydrochloride acid produce sodium chloride + sulfur dioxide+ sulfur+water
what the hell is on your shoulder? a moll? Telling you what to do?
anyone can tell me the rate law?
I wish to have so nice coat, thees colors, love it 🙂
Well i have Ligma Now , thanks alot jane
“Eacid”
ASSID
What was the concentration of the hydrochloric acid?
Mem, how can u find 0.15 moles/L
i actually wanna die
very cook lab coat!
Ayyycid
I have chemistry moderation tomorrow so I'm cramming this
What color is the cloud formed?
Good demonstration
1/time wat is it??
doesnt sodium thiosulphate + hydrochloric acid make sulphur+sodium chloride = water
Whatever is in her shoulder is a mole.. Not the animal but the measurement of the number of atoms, the mass of atoms and also the volume of atoms….
I have a quotion
What on her shoulder?
The graphs are wrong. In this case the time is the dependant variable should be placed on y axis.
Action sound in first scene hahahaha
Thank you so much this was very helpful
can you tell me , which solution you are adding in to the beaker?
Omg it's a Mole xD that so punny
whyyy
I love your lab coat 😅😅😅
