What else can I help you with?
Why will chalk dust sprinkled on a plastic sheet placed over a bar magnet NOT show the shape of the magnetic field?
Simple: chalk dust has no magnetic properties whatsoever, and is an insulator. As such, the magnetic field will flow right past it as if it weren't there, so it cannot position itself accordingly.
Why will chalk dust on a plastic sheet placed over a bar magnet not show the shape of the magnetic field?
Chalk dust (calcium carbonate) is not magnetisable.
Why does an iron nail has more force of attraction than a piece of chalk and rubber band?
Because they have different magnetic properties; iron is strongly ferromagnetic.
What is the rock that makes up white cliffs of dover?
chalk
What is the solute and solvent in chalk water?
Water is the solvent and chalk is the solute.

Is the chalk used in the schools magnetic?
No well i am just telling you the answer i think because i went to a school that had chalk boards.

Which has more force of attraction an iron nail a piece of chalk and a rubber band?
The iron nail has the greatest force of attraction due to its magnetic properties, followed by the piece of chalk which has minimal attraction, and the rubber band has the least as it is non-magnetic and non-conductive.

What is a separating technique?
A separation technique is something used to separate an object from it's mixture. For example, in a bowl you have chalk, chalk dust, salt, and paperclips. You'd use magnetic attraction to get the paperclips out. Then you'd use your hands and take out the chalk. And then, you use a sifting tool and it'll separate the salt and chalk dust by itself. But, another cool way to separate those two is to put them in water. The salt will eventually sink because it's denser than water, and the chalk dust will float because it is less dense. Other techniques are, filteration, sifitng, magnetic attraction, evaporation, chromotography. Hope that helped! :D
