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
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
why isn't the second one a double replacement as well?!?!? like the second precipitation one on the first page?
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.
thank you so much for making these videos!!!! they help so much
Thanks a ton
How do you know which compound is a solid, liquid, or gas? What are the rules for this?

Thank you 😊
this video gave me ASMR while teaching me chemistry thank you
so helpful! thanks
i’m tired
