Is adding HCl to Mg physical change?
No, adding hydrochloric acid (HCl) to magnesium (Mg) and observing the resulting chemical reaction is a chemical change, not a physical change. The reaction produces hydrogen gas and magnesium chloride, with new substances formed.
Is adding NaOH to HCL chemical or physical change?
When adding NaOH to HCl, a chemical change occurs because the two substances react to form a new compound, NaCl (table salt), and water. This is evidenced by the formation of a new substance with different properties than the original reactants.
Is adding HCl to Mg a physical or chemical change?
Adding HCl to Mg would result in a chemical change. The reaction between hydrochloric acid (HCl) and magnesium (Mg) produces hydrogen gas (H2) and magnesium chloride (MgCl2), which are new substances formed by a rearrangement of atoms. This is a chemical change because the composition of the substances involved is altered.
Is Na2SO4 plus HCl a chemical or physical change?
The reaction between Na2SO4 and HCl is a chemical change because it results in the formation of new substances (NaCl and H2SO4) with different chemical compositions compared to the reactants.
Is adding HCl to Mg a physical change?
No, adding hydrochloric acid (HCl) to magnesium (Mg) and observing the formation of magnesium chloride (MgCl2) is a chemical change because it involves the formation of new chemical substances with different properties.

Is bubbles when aluminuim wire is dropped into HCL a physical change?
No. The aluminum is reacting with the acid; it is a chemical change.
Why is mixing hydrochloric acid and sodium a chemical change?
It is a chemical change because the products, H2 and HCl, are completely different from the reactants in their physical and chemical properties.
Is adding HCl to Mg a physical change?
No, adding hydrochloric acid (HCl) to magnesium (Mg) and observing the formation of magnesium chloride (MgCl2) is a chemical change because it involves the formation of new chemical substances with different properties.
Is dissolution of hcl in water a physical change?
Dissolution of HCl in water is considered a physical change because the chemical composition of the substances remains the same. The HCl molecules dissociate into H+ and Cl- ions in the water without any new substances being formed.
Why is reaction of HCl and Zn chemical change?
The reaction of HCl and Zn is a chemical change because new substances are formed. In this reaction, hydrogen gas (H2) and zinc chloride (ZnCl2) are produced, which have different chemical properties than the reactants. Additionally, the reaction involves the breaking and forming of chemical bonds.
Is the solubility of HCl in water a physical phenomenon or a chemical reaction?
Dissolving HCl (or any other dissolvable compound, eg. sugar, salt) in water is physical.
Is dissolving carbon dioxide in water a physical or chemical change?
It's a physical change because carbon dioxide still has it's same properties. It is not changed.Added:Even if you dissolve it in water it is still there thus making it a physical change and not a chemical change. If it were a chemical change then it would be changed for example, fire or burning things like logs and so forth. Dissolving something in water is not changing it completely it only has a minor change in how you see it, thus it is a physical change.The only 'chemical' change might be considered to be the protolysis of water being slightly enhanced by the hydrogen bonding to carbon dioxide molecules. But that is more a (very weak) 'chemical' change of water molecules rather than of CO2 molecules:(CO2)aq + 2 (H2O)l > (Cl-)aq + (H3O+)aq
Are the physical and chemical properties of HCl different from those of H2 and Cl2?
Yes, HCl is a compound formed by the reaction of hydrogen and chlorine, so it has different properties from its constituent elements H2 (hydrogen gas) and Cl2 (chlorine gas). HCl is a polar molecule with acidic properties, while H2 and Cl2 are nonpolar molecules with different reactivity and chemical characteristics.
