Answer:
there must be free-moving electrons in a compound to conduct electricity.
in solid ionic compounds, there are no free electrons so it can't conduct electricity.
But in aqueous form the forces of attraction are broken and the ions (cations and anions) are free to move. This means there are free electrons that allow the aqueous compound to conduct electricity.

Answer:
There are 12 nanoseconds in 
.
Explanation:
We need to convert to nanoseconds.
We know that,
Now using unitary method to solve it such that,
So, there are 12 nanoseconds in .
the sun makes it evaporate quicker if it is there for longer
