General Chemistry Question #240000 Magnesium ribbon reacts with hydrochloric acid to produce hydrogen gas and magnesium chloride. Describe how this reaction could be used to determine the relative atomic mass of magnesium. Expert's answer In this experiment, students react magnesium ribbon with dilute hydrochloric acid to produce hydrogen gas.

Magnesium metal (in form of a ribbon or powder) reacts with acids rapidly than water liberating hydrogen gas. For stance, magnesium metal reacts with hydrochloric to form magnesium chloride salt while displacing hydrogen from the acid as hydrogen gas. This is as shown in the equation below: 2HCl (aq) + Mg (s) => MgCl2 (aq) + H2 (g)

A magnesium ribbon must be cleaned before burning in air because magnesium when exposed to air reacts with oxygen which leads to the formation of magnesium oxide on the surface of the magnesium ribbon. The formation of a layer of magnesium oxide on the magnesium ribbon might slow down the reaction.

Q1 Why should a magnesium ribbon be cleaned before burning in air? | Chemical Reactions and Equations | CBSE Class 10 ChemistryPresented by www.shikshaabhiya.

Why should magnesium ribbon be cleaned before burning in the air? Magnesium ribbon is made of pure magnesium metal. It is highly reactive with oxygen, resulting in the oxidation of magnesium when it comes into contact with air. It produces an oxide layer on the surface of the magnesium ribbon. This layer acts as a protective layer.

The magnesium ribbon should be cleaned before burning in the air because the layer of magnesium oxide (which is formed due to the reaction of magnesium with air ) can be removed in order to get the desired chemical reaction. Also in order to remove the oxide layer, the presence of which slowdowns the oxidation process.

Expert Answers yamaguchityler | Certified Educator Share Cite Since Magnesium is an reactive metal in the reactivity series, when it is exposed to oxygen it will form metal oxides. For example,.

Why Do You Need To Clean Magnesium Ribbon Before Burning It? Because magnesium is highly reactive, magnesium ribbon, when stored for any length of time, ends up with impurities on the surface (mainly magnesium oxide) and if you try to burn the ribbon with this in place, it won’t burn as it is supposed to.

Why should magnesium ribbon be cleaned before it is burnt in air ? A. Magnesium is an extremely reactive metal. When stored, it reacts with oxygen to form a layer of magnesium oxide on its surface. This layer of magnesium oxide is quite stable and prevents further reaction of magnesium with oxygen. The magnesium ribbon is cleaned by sand paper.
