Hydrochloric acid reacts with potassium hydroxide to produce a salt water and heat chemical or physical?
The reaction between hydrochloric acid and potassium hydroxide is a chemical reaction that forms water and potassium chloride salt. It is an exothermic reaction, meaning that heat is released as a result of the reaction.
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 Reaction of hydrochloric acid with sodium hydroxide a chemical change?
Yes, the reaction of hydrochloric acid with sodium hydroxide is a chemical change. It forms water and sodium chloride, which are different substances with new chemical properties compared to the reactants.
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 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).
Is Hydrochloric acid reaction with sodium hydroxide to produce salt water and heat a chemical change?
Yes, the reaction of hydrochloric acid with sodium hydroxide to produce salt (sodium chloride) and water is a chemical change. This is because a new substance (salt) is formed with different chemical properties than the original substances. Additionally, heat may be produced during the reaction, indicating a chemical change has occurred.
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 sodium and potassium react violently with water a chemical change?
Yes, the reaction between sodium/potassium and water is a chemical change. This reaction produces hydrogen gas and hydroxide ions, resulting in the formation of a new substance with different properties than the reactants.
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.
Is potassium a physical or chemical change?
Potassium is not a change; potassium (K) is a chemical element.
If hydrochloric acid is added to sodium hydroxide the temperature increases but there is no visible change did a chemical or physical change occur?
A chemical change occurred because the reaction between hydrochloric acid and sodium hydroxide generated heat, indicating a release or absorption of energy. Even though there may not be a visible change, the temperature increase is evidence of a chemical reaction taking place.
