damnnn thanks so much, this is was way more easier than my teacher ms han..teaches it, i understand the lessons on youtube more than the lessons my teacher explains lol..chemistry is a bust tho -.-
You're absolutely right. The instantaneous velocity at the bottom is about 1.98 m/s. I added an annotation to the video at 1:42. Thanks for pointing out my mistake!
@chemdog8 why have you subracted the heat enthalpies of the reactants in both the examples? aren't they supposed to be summations of the heat enthalpies of formations for both reactants and products?
it doesn't matter matter in the 1st example but the reactants have been subracted in the 2nd one... its makes a diference... is that correct?
Nice. This is a good supplement to my readings. My teacher sucks so I basically have to teach myself, but you made it easier for me to digest the material.
@10243406 Same here bro. My teacher covers it so briefly and we have these insane quizzes over the weekend for each new chapter... Any tips on how to survive this course?
@youlosez u think u got it bad? my "teacher" is some asian old fob that cant speak english for shit. he talks you down by saying "ur not smart, ur not a high achiever, u have bad logic/habits". he never teaches. he wastes his class time talking about his gay life and about helping other children in africa and how he used to be a black belt in karate when he was little (trying to be cool obviously). and at the end of class, he'll go "we'll have a stoichiometry test 2morrow, 20 points" WTF?!

i dont understand how you came up with v to be equal to .255
.196 divided by .5 is .392
.392 divided by m (which is .1) equals 3.92
and then the square root of 3.92 equals 1.97 which is v
how did u get .255?
