Is it a physical or chemical change when an antacid tablet reacts with hydrochloric acid?
It is a chemical change. Depending on the antacid, the active ingredient in the tablet (which is a base) will react with the hydrochloric acid to produce water, a salt, and sometimes carbon dioxide.
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 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 there a physical or chemical change in the reaction of calcium carbonate and hydrochloric acid?
It would be a chemical change because a new substance is formed (Calcium Chloride). A physical change doesn't change the substances involved, it just changes it appearance, such as ice melting, water freezing or becoming a vapor, or if you cut up a piece of paper.Physical changes can be reversed, while chemical changes can not. A chemical change involves a reaction, a new substance, and heat given off or absorbed. Burning paper is a chemical change, as is frying an egg, or burning gasoline.
Is it a chemical or physical change if a piece of ice melts and reacts with sodium?
Melting is a physical process; reaction with sodium is a chemical process.

Can silicon undergo a physical and chemical change?
Yes, silicon can undergo physical changes such as melting and crystallizing. It can also undergo chemical changes when it reacts with other elements, forming compounds like silicon dioxide (SiO2) or silicon carbide (SiC).
Is it a chemical or physical change if a piece of ice melts and reacts with sodium?
Melting is a physical process; reaction with sodium is a chemical process.
Why is chemical hydrochloric acid reacts with zinc?
2HCl + Zn -----> ZnCl2 + H2
Is strontium reacts with water a chemical or physical change?
When something reacts, that is a chemical reaction. Chemical change.
What type of chemical reaction takes plasce when ammonia reacts with hydrochloric acid?
When ammonia reacts with hydrochloric acid, a neutralization reaction occurs. The ammonia, which acts as a base, reacts with the hydrochloric acid, which acts as an acid, to form ammonium chloride and water.
What is the chemical formula for hydrochloric acid mossy zinc--- zinc chloride?
The chemical formula for hydrochloric acid is HCl. When hydrochloric acid reacts with mossy zinc, it forms zinc chloride, whose chemical formula is ZnCl2.
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.
