what is a physical quantity that you can measure to determine if the change is physical or chemical when two liquids are added together?
In: Chemistry
When it’s a chemical reaction it can cause all sorts of different effects. The easiest though is one of four things: it gets hotter, it gets colder, and/or it gains or loses mass due to gaseous release or capture.
There isn’t a singular quantity that encapsulates this phenomenon.
It’s an entire field of study based on chemistry.
Any test to see if there is a chemical change? Like NMR, mass spec, etc? If there is a different chemical moiety present, then you have chemical change.
