When ice cream melts from solid to liquid, the motion of the molecules increases. This is because as the phase change moves from solid to liquid to gas, entropy increases which increases the probability of the molecules to collide and move in the system. This increase may be because of the increase in temp, probable cause of the melting of icecream.
The transfer of electrons forms strong bonds between ions I’m pretty sure
Using an example like Christmas lights, I would say yes because normally a lot of them would go out if one light is broken.
Mn+2 is cation and CO3 is anion
hope it help
