Is iron dissolving in hydrochloric acid with the evolution of hydrogen gas a physical property?
No, this is a chemical property. When iron dissolves in hydrochloric acid, it undergoes a chemical reaction in which the iron atoms lose electrons and form iron(II) chloride, while hydrogen gas is evolved. This is a chemical change, not a physical change.
Is hydrochloric acid a homo or hetero mixture or pure substance element or compound?
Hydrochloric acid is a chemical compound composed of hydrogen and chlorine atoms. It is not a pure element, but rather a compound.
When hydrochloric acid is mixed with calcium is that a chemical or a physical reaction?
The reaction between hydrochloric acid and calcium is a chemical reaction because new substances are formed. In this reaction, calcium displaces hydrogen from hydrochloric acid to produce calcium chloride and hydrogen gas. This process involves a rearrangement of atoms and the formation of different chemical bonds.
Is Hydrogen fluoride anhydrous the same as Hydrofluoric Acid?
No, hydrogen fluoride anhydrous is the anhydrous (without water) form of hydrogen fluoride, while hydrofluoric acid is the aqueous (dissolved in water) form of the compound. Both substances contain the HF molecule but differ in their physical state.
Why hydrochloric acid and hydrogen chloride gas have different names?
Hydrochloric acid is the aqueous form of hydrogen chloride gas, where hydrogen chloride gas dissolves in water to form hydrochloric acid. The name difference reflects the different physical states of the substance: hydrogen chloride gas is a compound in its gaseous state, while hydrochloric acid is the same compound but in its dissolved form in water.
Is iron dissolving in hydrochloric acid with the evolution of hydrogen gas a physical property?
No, this is a chemical property. When iron dissolves in hydrochloric acid, it undergoes a chemical reaction in which the iron atoms lose electrons and form iron(II) chloride, while hydrogen gas is evolved. This is a chemical change, not a physical change.
When iron is immersed in a solution of hydrochloric acid hydrogen gas is produced a physical or chemical property?
This is a chemical reaction.

This process involves a rearrangement of atoms and the formation of different chemical bonds.
Is a dissolving zinc in acid a chemical change or physical change?
Dissolving zinc in acid is a chemical change. It really isn't being dissolved, it is reacting with the acid to form new substances. For example, if you react zinc with hydrochloric acid, the products will be zinc chloride and hydrogen gas. The zinc seems to dissolve, but it is actually combining with the chlorine in the hydrochloric acid. Zn + 2HCl ---> ZnCl2 + H2
Is Hydrogen fluoride anhydrous the same as Hydrofluoric Acid?
No, hydrogen fluoride anhydrous is the anhydrous (without water) form of hydrogen fluoride, while hydrofluoric acid is the aqueous (dissolved in water) form of the compound. Both substances contain the HF molecule but differ in their physical state.

Hydrochloric acid is the aqueous form of hydrogen chloride gas, where hydrogen chloride gas dissolves in water to form hydrochloric acid. The name difference reflects the different physical states of the substance: hydrogen chloride gas is a compound in its gaseous state, while hydrochloric acid is the same compound but in its dissolved form in water.
What are the physical properties of hydrogen chloride?
Hydrogen chloride is a colorless gas at room temperature with a pungent odor. It is highly soluble in water, forming hydrochloric acid. It is corrosive to metals and can cause severe burns if inhaled or exposed to skin.
When hydrogen burns in chlorine gas it is a physical or chemical change?
When hydrogen burns in chlorine gas, it undergoes a chemical change. This is because new substances are formed as a result of the reaction, such as hydrogen chloride. The properties of the starting materials are different from those of the products.
What are 2 qualitative physical properties of hydrochloric acid What are 2 quantitative physical properties of hydrochloric acid What are the main uses for Hydrochloric acid How is it produced?
Qualitative physical properties of hydrochloric acid are its strong, pungent odor and its clear, colorless appearance when in pure form. Quantitative physical properties include its boiling point of -85 degrees Celsius and its density of roughly 1.2 g/cm^3 at room temperature. Hydrochloric acid is commonly used in chemical synthesis, metal cleaning, and as a laboratory reagent. It is primarily produced by dissolving hydrogen chloride gas in water, typically using the contact process or the wet sulfuric acid process.
Is it physical changes or chemical changes when hydrochloric acid reacts with zinc?
When hydrochloric acid reacts with zinc, it is a chemical change because new substances are formed. The reaction produces zinc chloride and hydrogen gas, which are different from the reactants.
What is an instrument used to dissolve heat?
Heat is not a physical substance which can be dissolved.
