When mixing powder paint and water then boiling that water what is left behind?
The residue is the paint powder.
Is salt dissolving in water and leaving a white residue a physical or chemical change?
Salt dissolving in water is a chemical change, the white residue is left when the water gets saturated by the salt and the salt starts to come out of solution to gain equilibrium. The residue can also be left behind when boiling off the water.
What are two ways that you could tell the difference between pure water and salt water?

What is the residue when sodium chloride water solution was heated to dryness?
When a mixture of sodium chloride and water is heated to dryness, the residue is sodium chloride, because the boiling point of sodium chloride is much higher than the boiling point of water.
How can boiling point be used to find out if a substance is pure?
At Boiling Point all the material evaporates leaving no residue which means it is pure. But if it leaves some residue after evaporating at boiling point then it is not pure. For example : If you take an example of pure water & Saline Water then pure water will evaporate at its boiling point leaving nothing after it. But Saline water evaporates leaves salt behind it.

How could you find the difference between salt water and pure water without tasting it?
By simply boiling the water, and checking if there is any salt residue.
Is it safe to eat pasta from a pot of soapy water for example if some washing soap residue was left over in the pot and the water was very bubbly when boiling?
The pasta is safe to eat, anytime pasta is boiled the water gets very bubbly and was most likely not soap residue. If it was soap residue it would have bubbled when you filled the pot with water.

What is distillied water?
Distilled water has undergone a process called Distillation in order to remove impurities. The method involves boiling water and collecting the steam which is then condensed, while any impurities are left as residue.
What is the element in a kettle called?
If you're referring to the residue left in the kettle after the boiling of water. It is known as calcium carbonate. The chemical equation is CaCO3. Hopes This Helps
Why evaporation is better than boiling to obtain salt from sea water?
If you can evaporate the water to leave the salt residue, you may be expending less energy that if you do that by boiling. This would be especially true if you use natural evaporation from ponds or similar impoundments. Then you are letting the sun do the work for you.
