hydrogen peroxide mix with magnesium ribbon produced hydrogen gas
This is a true statement. When hydrogen peroxide is mixed with magnesium ribbon, a chemical reaction occurs and hydrogen gas is produced as one of the products. The balanced chemical equation for this reaction is:
2 H2O2 (aq) + 2 Mg (s) → 2 MgO (s) + 2 H2O (l) + H2 (g)
The magnesium reacts with the hydrogen peroxide to produce magnesium oxide and water as well as hydrogen gas. This is known as a displacement reaction, where the more reactive magnesium takes the place of the hydrogen in the hydrogen peroxide molecule, resulting in the formation of hydrogen gas.
Yes, when hydrogen peroxide is mixed with magnesium ribbon, it produces hydrogen gas.
Here is a step-by-step explanation of the reaction:
1. Gather the necessary materials: hydrogen peroxide (H2O2) and a piece of magnesium ribbon.
2. Prepare a safe and appropriate working environment. Ensure there are no flammable materials nearby and wear appropriate safety equipment like gloves and goggles.
3. Cut a small piece of magnesium ribbon, around 2-3 centimeters long. Ensure the ribbon is clean and free from any oxide layer by scraping it gently with sandpaper.
4. Place the piece of magnesium ribbon into a container or a test tube.
5. Now, slowly pour hydrogen peroxide into the container or test tube, making sure it completely covers the magnesium ribbon.
6. As soon as the hydrogen peroxide comes in contact with the magnesium ribbon, a reaction will occur. You will observe effervescence and bubbling, indicating the release of gas. In this case, the gas being released is hydrogen gas (H2).
The chemical equation for this reaction is:
2 H2O2 (aq) + 2 Mg (s) -> 2 MgO (s) + 2 H2 (g)
Note that magnesium oxide (MgO) is also formed as a product of this reaction.
Please remember to exercise caution when conducting chemical reactions and always follow proper laboratory safety protocols.
