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 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 it physical changes or chemical changes when hydrochloric acid reacts with zinc?
It is a chemical change. Hint: if something is a reaction it is probably a chemical change.
Is a drop of hydrochloric acid on marble produces carbon dioxide gas a chemical change?
Yes, the reaction between hydrochloric acid and marble to produce carbon dioxide gas is a chemical change. This is because new substances are formed (carbon dioxide gas) with different properties from the original substances (hydrochloric acid and marble), indicating a chemical reaction has occurred.
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 mixing aluminum and hydrochloric acid a chemical change?
Be careful with your terminology.Mixing aluminum and hydrochloric acid is not a chemical change.The resulting reaction, however, is a chemical change.
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.
What type of energy change associated with chemical reaction between magnesium and hydrochloric acid?
This reaction is exothermic.

Mix mossy zinc to a dilute hydrochloric acid is it physical change or chemical change?
Mixing mossy zinc with dilute hydrochloric acid is a chemical change because a reaction occurs resulting in the formation of zinc chloride and hydrogen gas. This reaction is accompanied by a change in chemical composition, making it a chemical change.
Is iron that dissolved in hydrochloric acid with the evolution of hydrogen gas a physical property?
The solubility of iron in hydrochloric acid is a chemical property, not a physical property. This reaction involves a chemical change where iron reacts with hydrochloric acid to form iron chloride and hydrogen gas is evolved.
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.
What colour does hydrochloric acid go when magnesium is added?
When magnesium is added to hydrochloric acid, a chemical reaction takes place, resulting in the formation of magnesium chloride and hydrogen gas. The color of the hydrochloric acid does not change significantly during this reaction.
Mixing magnesium and the product of burning magnesium with hydrochloric acid is it a physical or chemical change?
Mixing magnesium and the product of burning magnesium with hydrochloric acid would lead to a chemical change. The reaction between magnesium oxide (product of burning magnesium) and hydrochloric acid would produce magnesium chloride and water, showing a chemical reaction taking place due to the formation of new substances with different properties.
