What is the chemical formula for potassium metal?
Since Potassium is a element it does not have any chemical formula. It has a chemical symbol K, which is derived from its Latin name Kallium.
Is decomposing water by passing an electric current through it a chemical or physical change?
Decomposing water by passing an electric current through it is a chemical change because it involves the breaking of the chemical bonds in water molecules (H2O) to form hydrogen gas (H2) and oxygen gas (O2). This reaction results in the formation of new substances with different chemical properties.
What is the balanced chemical equation for potassium metal and chlorine gas react?
The balanced chemical equation for the reaction between potassium metal and chlorine gas is: 2K(s) + Cl2(g) -> 2KCl(s), where potassium metal reacts with chlorine gas to form solid potassium chloride.
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).
What is the chemical equation of potassium metal and chlorine gas combine to form potassium chloride?
The chemical equation is:2 K + Cl2 = 2 KCl

Is potassium a compound or a element?
Potassium is an element with the chemical symbol K and atomic number 19. It is a soft, silvery-white metal that belongs to the alkali metal group of the periodic table.
Is K2CO3 a metal?
Potassium carbonate is a compound, not a chemical element.
Is sodium metal exploding in water a physical property?
No, sodium metal exploding in water is a chemical reaction, not a physical property. Physical properties are characteristics that can be observed or measured without changing the substance's composition, such as color, density, or melting point.

What is the chemical equation of potassium metal and chlorine gas combine to form potassium chloride?
The chemical equation is:2 K + Cl2 = 2 KCl
When a small piece of potassium is dropped into a beaker of water the potassium moves about rapidly and then ignites within secounds the metal is gone and all activity ceases Is that chemical change?
Yes, according to wikipedia: Potassium reacts very violently with water producing potassium hydroxide (KOH) and hydrogen gas.2 K (s) + 2 H2O (l) → 2 KOH (aq) + H2 (g) This is a chemical change.
What is the chemical equation potassium metal and chlorine gas combine to form potassium chloride?
The chemical equation for the reaction between potassium metal and chlorine gas to form potassium chloride is: 2K + Cl2 -> 2KCl
Is a metal surface being ground a chemical change?
A metal Surface being ground is a physical change, not a chemical change.
What is the element KBr?
The chemical formula KBr is an ionic compound (made from a metal and a non-metal). K represents the metal potassium, and Br represents bromine (a non-metal halogen). The proper chemical name is potassium bromide.
