Given :
Mass of toluene: 55.0 g
Density of toluene: 0.87 g/mL
Now we know Volume = mass/density
Substituting these values we get
Volume = 55.0 g÷0.87 g/mL
Volume = 63.22 mL
Protons = +1
negatrons = -1
neutrons = 0
<span>electrons = -1
</span>
<span>negatrons are like positrons and they are subatomic particles and are not present in atoms
</span>
so electrons are negatively charged and are present in atoms
hope that helps
Answer is D, they are compressible
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.
