Heating magnesium is a physical process.
But the reaction of magnesium with oxygen at high temperature is a chemical process.
Magnesium is not a change of any sort. It is a metallic element that can undergo both physical an chemical changes.
Yes, because the chemical structure is compromised
Adding acid to magnesium ribbon results in a chemical change because it produces hydrogen gas and magnesium ions through a reaction. This change can be observed by the formation of bubbles (hydrogen gas) and the dissolution of the magnesium ribbon. Unlike physical changes, the original substances (magnesium and acid) are transformed into new products with different chemical properties. The reaction can be represented by the equation: Mg + 2HCl → MgCl₂ + H₂.
Hi
its a chemical lol
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.
Magnesium is not a change of any sort. It is a metallic element that can undergo both physical an chemical changes.
Adding Hydrochloric acid to magnesium induces a chemical change, according to the reaction: Mg(s) + 2HCl(aq) > MgCl2(aq) + H2(g)
When magnesium sulfate dissolves in water, it undergoes a physical change, not a chemical change. The molecules of magnesium sulfate are simply dispersed in the water, but no new chemical substances are formed.

The reaction between magnesium and oxygen to form magnesium oxide is a chemical change. This is because new substances with different properties are formed during the reaction.
Hi
It's a physical change because it might be in a different form but it's still magnesium
It is a physical change.
No, magnesium burning is a chemical change because the magnesium undergoes a chemical reaction with oxygen to form magnesium oxide. Physical changes do not alter the chemical composition of a substance, whereas chemical changes do.
