Is hydrochloric acid reacts with potassium hydroxide to produce a saltwater and heat a physical or chemical change?
Chemical Change
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!
When hydrochloric acid is mixed with calcium is that a chemical or a physical reaction?
chemical how do you know?
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.
What is the physical state of potassium hydroxide at room temperature?
Solid state in room temperature.

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

What is the physical state of potassium hydroxide at room temperature?
Solid state in room temperature.
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.
Is mixing lye and hydrochloric acid a physical or chemical change?
it is a chemical change because it is no longer hydrochloric acid but a substance that has a different "ingredient" than it
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)
When copper sulfate mixed with sodium hydroxide is a form of physical change or chemical change?
Chemical change (which results in physical change).
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).
