Yes it is a physical change because you can still put it back together
The reaction of a magnesium ribbon fizzing in acid is a chemical change. This is because new substances are formed during the reaction as the magnesium reacts with the acid to produce magnesium ions and hydrogen gas.
Yes! beacuse you are not creating a new substance and making something new just changing a the appearance!
that is magnesium itself, in the form of a ribbon
magnesium + oxygen gas ----D magnesium oxide
When magnesium ribbon burns, it produces a bright white light and forms magnesium oxide as a white powder residue.
Burning a magnesium ribbon is a chemical change because the magnesium reacts with oxygen in the air to form magnesium oxide. This results in a new substance being formed with different chemical properties than the original magnesium ribbon.

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.

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.
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.
Yes, after burning, the magnesium ribbon undergoes a chemical change and forms magnesium oxide. The properties of the magnesium ribbon and oxygen have changed to form a new compound with different properties than the original elements.
Yes. Magnesium ribbon is magnesium metal in the shape of a ribbon.
No. Magnesium ribbon is nearly pure magnesium, which is an element.
Magnesium ribbon is silver colored.
Oxygen is colorless and gas at physical state.
