Is potassium cloride dissolving in water a chemical change?
Potassium metal does not dissolve in water, it is so reactive that it rips water molecules apart releasing hydrogen gas and combining with the remaining hydroxyl group to form potassium hydroxide (potash lye) which then dissolves in the water. This chemical reaction releases so much heat that it ignites the hydrogen gas that was emitted which produces water vapor/steam and a light purple flame (caused by excited potassium ions).
Is the exploding of potassium metal in water a chemical change?
Yes, the exploding of potassium metal in water is a chemical change. This reaction involves the formation of new substances (potassium hydroxide and hydrogen gas) with different chemical properties than the original substances (potassium metal and water).
What is the flame test for potassium and sodium when both are present.?
When both potassium and sodium are present, the flame test may show a mixture of colors. Sodium typically produces a bright yellow flame, while potassium emits a lilac flame. However, the colors might blend together or appear differently due to the different concentrations of each element in the sample.
As you move from potassium to krypton in the fourth period of the periodic table the elements will change from?
As you move from potassium to krypton in the fourth period of the periodic table, the elements will change from a metal (potassium) to a nonmetal (krypton). Potassium is a metal, while krypton is a noble gas and therefore considered a nonmetal.
Why is methylcyclopentanol does not change the colour of potassium permanganate?
Methylcyclopentanol does not change the color of potassium permanganate because it is not easily oxidizable by the permanganate ion. The structure of methylcyclopentanol does not provide the necessary functional groups or carbon-hydrogen bonds that can be readily oxidized by potassium permanganate.
Is potassium a physical or chemical change?
Potassium is not a change; potassium (K) is a chemical element.
Can golden retreivers change colors?

Does phosphorus change colors?
The Phosphorus change colors is Chameleons.
When naming a compound containing potassium and chlorine change the suffix of the anion name to?
When naming a compound containing potassium and chlorine, you change the suffix of the anion name to "-ide." In the case of potassium and chlorine forming KCl, the compound is named potassium chloride.

Is dropping a potassium in a water a physical change?
yes it is a physical change !
Is Heating potassium chlorate a chemical or physical change?
Heating anything to a visible change is ALWAYS a chemical change
How can you differentiate between sodium chloride salt and potassium salt?
The colors in the flame test are different (yellow for sodium, lilac for potassium).The taste is also different.
