꒰ exp :: 1 mol chem + 1 mol intro reacting ꒱ wlcm !! let's learn about chem ! ik it's not the beginning of the school yr,, but this is *always* helpful !! whoops,, forgot to specify what “this” is !! this prj is a few notes and safety tips to read over b4 starting chem !! (why do i like using two exclamation marks so much ??) < #1 :: safety first ! > “yeah,, yeah,, ik” i can hear u saying that… (jk) if u r taking chem,, chances are that u r actually doing labs during class. and there r dangerous chemicals. and those dangerous chemicals could splash into your face. or your eyes. and trust me,, it *will* hurt. this is why u need to wear safety goggles,, gloves,, and preferably some kind of apron or lab coat. make sure to always pull your gloves all the way up to ur sleeve,, and try to keep ur face away from the chemicals. note: never sniff a chemical directly !! use the “wafting” method. or u could burn the inside of ur nose. always handle chemicals carefully !! u can always look up the full list of safety guidelines if u want,, i just don't want to bore ygs too much. < #2 :: another lab thing... > i didn't know what to title this one lol,, but always make sure to read over the whole lab b4 starting the exp !! aha,, it's called *pre-reading* !! trust me,, i've not read labs over and then wasted a bunch of chemicals...ur chem teacher is not gonna like that. < #3 :: units,, units,, units !! > this is for calculations. units are *imperative* !! how r u supposed to know if u have 3 Cu atoms,, or 3 Co atoms ?? BIG difference !! besides that,, u'll be converting btw diff scales depending on what data u r given. i'll show u how to do dimensional analysis in the next prj !! < #4 :: the very,, very,, important...SIG FIGS !! > alr,, u say,, "uh,, figs ?? i like figs !! they're tasty !!" nope,, these aren't figs. sig figs is short for significant figures,, which are some math rules u need to follow. i'll make a prj abt that too,, unless u want to look up a YT tutorial that's wayyy better. < :: concepts vs memorization > there's a LOT of formulas...but it's easier to know it through concepts than being like :: PV = nRT !! PV = nRT !! PV = nRT !! instead,, just remember why pressure is inversely proportional to volume,, or why temperature is proportional to pressure !! okay that was kinda short guys !! i'll post an intro abt electrons, protons, and neutrons soon !! byeeeee !! « exp completed »
