Select all that apply. Salt dissolved in water is a solution, therefore .

salt and water are chemically combined
salt is not chemically bonded to water
the quantity of salt and water is fixed
the ratio of salt to water may vary
salt and water retain their own chemical properties

No because it not possibly

Ametal with a large number of free flowing electrons most likely has good conductivity

First up write the aim
then write the materials reqd.
then the procedure which you follow
then observation
then conclusion
then you can write lab safety rules or precautions(you can avoid if u want).
lemme' give an example
aim: to observe the double displacement reaction
materials reqd: bacl2 and na2so4, test tubes and a dropper
procedure:
1. take bacl2 in a test tube and na2so4 in the other.
2. then pour bacl2 into na2so4 solution.
3. observe
observation:
you will see that a white precipitate is formed called baso4. along with that common salt or nacl is formed.
the equation is
bacl2+na2so4=baso4+2nacl
conclusion:
a double displacement reaction is observed.
hope it
