I'm saying the phase based on the phase labels that you can see after the chemical formula - (s) for solid, (l) for liquid, (g) for gas, and (aq) for aqueous, which means dissolved in water.
@@TonyStJohn Without having those labels, is there a way to tell if a compound is a solid, liquid, gas, or aqueous, just by looking at the chemical code?
@@konstantinrebrov675 Very interesting question! The answer is yes, but really only after years of study and very good understanding of intermolecular forces. For instance, at room temperature, Chlorine is a gas, Bromine is a liquid, and Iodine is a solid. This has to do with the intermolecular forces working between the molecules of each. Likewise, if we look at hydrocarbons - propane is a gas, pentane is a liquid, and once you get to very large hydrocarbon chains you end up with solids. Salts (metal cation + non-metal anions) will always be solids unless they are dissolved in water (then they will be aqueous) - and the reason for this is again due to the attractions between the chemical species.
@@TonyStJohn Iodine is a liquid at room temperature. I know this because I have a small bottle with liquid iodine for first aid purposes. There is no precipitation inside the bottle at all.
@@konstantinrebrov675 that iodine you have is actually a solution of iodine - so it is mixed with water or ethanol most likely. Elemental iodine is a solid at room temperature: en.wikipedia.org/wiki/Iodine
thank you so much for making these videos!!!! they help so much
This helped so much, thank you! I was so confused with the difference between precipitation and acid base reaction
the FeSO4+PbCl2 one I got wrong, is precipitation and double replacement.
1:55 why wasn't that a double reaction as well?
Good catch! You are right.
@@TonyStJohn ayyy im smart enough to notice the mistake :)
that means you're learning :D
Thank you 😊
so helpful! thanks
Thanks a ton
i’m tired
why isn't the second one a double replacement as well?!?!? like the second precipitation one on the first page?
this video gave me ASMR while teaching me chemistry thank you

How do you know which compound is a solid, liquid, or gas? What are the rules for this?
