Answer:
When melted or dissolved in water.
Explanation:
Potassium bromide in its solid form contains ions, which are charged atoms. Through the heating process, the melted potassium bromide becomes an ionic liquid. If solid potassium bromide is dissolved, for example in water, the resulting release of ions allows it to conduct electricity.
Answer:
ΔS> 0 means Letter A
Explanation:
Processes that involve an increase in entropy of the system (ΔS > 0) are very often spontaneous; however, examples to the contrary are plentiful. By expanding consideration of entropy changes to include the surroundings, we may reach a significant conclusion regarding the relation between this property and spontaneity. In thermodynamic models, the system and surroundings comprise everything, that is, the universe, and so the following is true:
\displaystyle \Delta {S}_{\text{univ}}=\Delta {S}_{\text{sys}}+\Delta {S}_{\text{surr}}
The scientist observes at what rate is the concentration increasing or decreasing.
The compound is CH₃CH₂CH₂NH₂
when naming the compound the C chain has 3 C atoms and they all are in a single chain therefore alkane chain is propane.
It has a -NH₂ group attached to the C therefore functional group is 'amine'
-NH₂ is attached to a terminal C atom therefore when numbering the C atoms the C attached to the substituent should have the lowest number therefore C atom with NH₂ is carbon atom 1
therefore name of the compound is 1-propanamine
