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 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.
What is the enthalpy change when hydrochloric acid reacts with magnesium?
The enthalpy change when hydrochloric acid reacts with magnesium is exothermic, meaning it releases heat energy.
What is the enthalpy change when magnesium reacts with hydrochloric acid?
The enthalpy change when magnesium reacts with hydrochloric acid is exothermic, meaning it releases heat energy.
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.
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.
Which of the following is a chemical property of hydrochloric acid?
The ability of hydrochloric acid to react with metals to produce hydrogen gas is a chemical property. This reaction demonstrates the acid's ability to undergo a chemical change by reacting with other substances.
Is adding hydrochloric acid to magnesium ribbon a physical or chemical?
Adding hydrochloric acid to magnesium ribbon results in a chemical reaction. The magnesium reacts with the hydrochloric acid to produce magnesium chloride and hydrogen gas. This process involves the breaking and forming of chemical bonds, indicating a change in the substance's chemical identity. Thus, it is a chemical change rather than a physical one.
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.
Why is chemical hydrochloric acid reacts with zinc?
2HCl + Zn -----> ZnCl2 + H2
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 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.
