Is adding NaOH to HCL chemical or physical change?
It is a chemical change. NaCl + H2O
Is adding HCl to Mg a physical or chemical change?
No, a new substance is formed so therefore it is a chemical change. dr. citrin for life
Is adding HCl to Mg physical change?
No. There is a change in substance taking place, so it would be considered a chemical change.
Is Na2SO4 plus HCl a chemical or physical change?
chemical
Is adding HCl to Mg a physical change?
chemical because when you add the chemical together you get a reaction that transforms the substance into another one. if im wrong please update this answer because this question could be on your test

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.

Why is reaction of HCl and Zn chemical change?
When HCl and Zn react they form two entirely new substances (H2 and ZnCl2). The change cannot be reverse by physical means.
Are the physical and chemical properties of HCl different from those of H2 and Cl2?
Yes, HCl, Cl and H have very different chemical and physical properties.
Is dissolution of hcl in water a physical change?
Yes
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
