If an electrical device falls in water in which you are standing, you could receive a fatal shock. Why
is this possible?
A
This is possible because small amounts of dissolved ions in the water allow to conduct
electricity.
B
This is possible because small amounts of dissolved nonmetals in the water allow to
conduct electricity.
OC
This is possible because small amounts of the electricity are attracted to water
molecules.
D
This is possible because small amounts of dissolved molecular compounds in the water
allow to conduct electricity.
