Is hydrochloric acid reacts with potassium hydroxide to produce a saltwater and heat a physical or chemical change?
The reaction of hydrochloric acid with potassium hydroxide is a chemical change because new substances (salt and water) are formed that have different chemical properties than the original reactants. The release of heat is an indicator of a chemical reaction taking place.
Is iron hydroxide and hydrochloric acid a physical or chemical reaction?
The reaction between iron hydroxide and hydrochloric acid is a chemical reaction because it involves a rearrangement of atoms to form new substances with different properties. The iron hydroxide reacts with the hydrochloric acid to form iron chloride and water.
Is it a physical or chemical change when hydrochloric acid reacts with sodium hydroxide to produce a sat water and heat?
It is a chemical change because the reactants (hydrochloric acid and sodium hydroxide) are undergoing a chemical reaction to form new substances (water and salt) with different properties. The heat produced is a sign of a chemical reaction taking place.
Is mixing lye and hydrochloric acid a physical or chemical change?
Mixing lye (sodium hydroxide) and hydrochloric acid results in a chemical change, known as a neutralization reaction. This reaction produces water and salt as products, and involves the formation of new chemical bonds and the release of energy in the form of heat.
Is hydrochloric acid reacting with sodium hydroxide to produce salt water and heat a physical or chemical change?
chemical as it is a permanent change and looks nothing like the starting reactant!

Is potassium a physical or chemical change?
Potassium is not a change; potassium (K) is a chemical element.

Is physical or chemical reaction takes place when sodium hydroxide mixed with water?
It is a physical change. The sodium hydroxide dissolves, but it is still sodium hydroxide.
Is Sodium hydroxide dissolving in water a chemical or physical change?
The dissolving of sodium hydroxide in water is a physical change because no new substances are formed. Sodium hydroxide breaks down into its ions in the water, but its chemical composition remains the same.
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 are some of potassiums physical and chemical proporties?
Physical: In pure form it is a shiny metal. It has a low density. It is malleable. Chemical: In pure form it corrodes easily upon exposure to air. It reacts violently with water to form potassium hydroxide and release hydrogen gas.
Does magnesium hydroxide dissolve in water?
Magnesium oxide does not "dissolve" in hydrochloric acid. Dissolution is a physical change. When magnesium oxide is mixed with hydrochloric acid, a chemical reaction takes place: Mg(s) + 2HCl ---> MgCl2(aq) + H2(g)
What is the physical state of potassium hydroxide at room temperature?
Potassium hydroxide is a white, solid substance at room temperature. It is commonly found in the form of pellets, flakes, or powder.
