Yes! beacuse you are not creating a new substance and making something new just changing a the appearance!
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.
When magnesium ribbon reacts with hydrochloric acid (HCl), magnesium chloride forms along with hydrogen gas being produced as a byproduct. The chemical equation for this reaction is: Mg (s) + 2HCl (aq) → MgCl2 (aq) + H2 (g)
Mg(s) + 2HCl(aq) ---> MgCl2(aq) + H2(g)
Science Sucks!!!!!!!! i know and im Liz i have to do a project due 2morrow and i havent even started
Adding Hydrochloric acid to magnesium induces a chemical change, according to the reaction: Mg(s) + 2HCl(aq) > MgCl2(aq) + H2(g)
physical because its not changing the object to a different object its just changing the texture.
Burning a strip of magnesium ribbon is a chemical change because the magnesium reacts with oxygen in the air to form magnesium oxide. This reaction results in the formation of new substances with different properties than the original magnesium ribbon.
The formula of magnesium ribbon is simply Mg, representing a single magnesium atom.

When magnesium ribbon reacts with hydrochloric acid (HCl), magnesium chloride forms along with hydrogen gas being produced as a byproduct. The chemical equation for this reaction is: Mg (s) + 2HCl (aq) → MgCl2 (aq) + H2 (g)
The burned magnesium ribbon is primarily magnesium oxide, which reacts with water to form magnesium hydroxide according to the equation MgO + H2O => Mg(OH)2.
Any reaction occur.
Mg(s) + 2HCl(aq) ---> MgCl2(aq) + H2(g)
Adding Hydrochloric acid to magnesium induces a chemical change, according to the reaction: Mg(s) + 2HCl(aq) > MgCl2(aq) + H2(g)

that is magnesium itself, in the form of a ribbon
The balanced reaction when magnesium ribbon reacts with oxygen in a flame is: 2 Mg(s) + O2(g) -> 2 MgO(s)
