The evidence that would lead you to believe that a residue was potassium chloride is it's white crystalline structure. When potassium chloride is mixed with water and the water evaporates, it leaves behind small potassium chloride crystals.
A general limit to observe is a maximum rate of 0.5 mg/kg/hr of potassium supplementation.
The white precipitate of silver chloride will dissolve when aqueous ammonia is added.
Naturally, Sodium is a metal (solid) and chlorine is a gas, so they only react at high temperatures or pressure. When they do react, they form crystals (sodium chloride).
Darwin found fossils that were similar but not the same as living species.Living species might have some relationship to the fossil form. In order for such changes to occur, Darwin figured that earth must be much older than 6000 years.
A: If you put a piece of copper wire on any type of flame (most preferably cooking flames), then you would observe that they produce a green color in the flame. Sometimes, it might give youa blue tinge but if it doesn't, it doesn't mean that there's something wrong with the copper you're using.
If chloride is present silver chloride with get precipitated..
I believe we only observe.
there is no change
A general limit to observe is a maximum rate of 0.5 mg/kg/hr of potassium supplementation.

The melting point of sodium chloride is 801 0C.
The dihydrated salt is blue-green.
You do an experiment to gather this evidence and then develop a hypothesis to explain what you observe.
the scientists name was brown
You would observe precipitation of magnesium hydroxide.
That is something that can only be seen by people who look for it (or observe the world, nature).
Got better when diet changed
