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?
Hydrogen is a pure substance because it is an element
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?
Because they are two physically different, albeit closely-related chemical compositions:Hydrochloric acid is what is generally used as a strong acid in industry and retail for use in swimming pools. It is an aqueous solution of HCl, which is a strong acid and therefore dissolves fully in the solvent (water) existing as it's constituent ions H+ and Cl-, separated and interacting with the very polar water molecules. Hydrochloric acid cannot be simply dried/evaporated to create Hydrogen Chloride.Hydrogen Chloride is the anhydrous form of the molecule HCl as a ionic molecule. It is sometimes referred to as dry HCl or HCl(g), since there is no solvent present and at STP it exists as a gas. This Hydrogen Chloride can be simply bubbled through water to produce Hydrochloric acid. The reverse transformation is not possible, instead a chemical reaction must be used to create Hydrogen Chloride from various reagents (such as Sulfuric acid and Sodium Chloride)

When iron is immersed in a solution of hydrochloric acid hydrogen gas is produced a physical or chemical property?
This is a chemical reaction.

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 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 are the physical properties of hydrogen chloride?
Undiluted Hydrochloric acid is a clear thick colorless liquid. Hydrogen chloride is composed of diatomic molecules, each consisting of a hydrogen atom H and a chlorine atom Cl connected by a covalent single bond.
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?
It is a chemical change. Hint: if something is a reaction it is probably a chemical change.
