What type of chemical reaction is the burning of magnesium?
Oxidation reaction 2Mg + O2 ----------- 2MgO
Is Mg burned in air chemical or physical?
Burning Mg in air is a chemical change. When magnesium reacts with oxygen in the air, it forms magnesium oxide. This is a chemical reaction that results in the formation of a new substance with different properties than the original magnesium.
What is a competition reaction?
A competition reaction is when two or more reactants compete for the same reactant in a chemical reaction. This competition can impact the reaction outcome by influencing which product is formed or how quickly the reaction takes place. It is common in complex reaction systems where multiple reactions can occur simultaneously.
How does the Mg ribbon differ from the Magnesium Oxide formed after burning the metal?
2Mg^2+ + O2 -- > 2MgO This is the chemical reaction occurring when burning magnesium. When burning the metal in air, which is slightly less than 20% O2, there is less O2 for the Mg to react with than there would be in a pure O2 environment. In the high O2 concentration environment the Mg doesn't have to "wait" for more O2 to diffuse into the area before the reaction can occur. In the case of burning Mg in air, the O2 conc. is much lower, and therefore depleted faster, and in turn must "wait" for more O2 to diffuse into the area. The reason it seems to burn hotter and bright is because all the energy being release from the combustion is able to happen much faster in the pure O2 environment. Provided you were burning the same mass of Mg, the same TOTAL amount of energy is released in both reactions, the pure O2 environment just allows it to happen in a shorter time frame. Energy released reacting (enthlapy of combustion)1 mol of Mg = -1200 kJ/mol regardless of the O2 saturation in the environment. Reacting it in a pure oxygen environment just allows the reaction to happen faster.
What are the half reaction for a galvanic cell with Ni and mg electrodes?
Ni2+(aq) + 2e- Ni(s) and Mg(s) Mg2+(aq) + 2e-
Why is water added to The Crucible in order to complete the conversion to magnesium oxide?
Water is added to the crucible to convert magnesium (Mg) to magnesium oxide (Mg(OH)2) because when magnesium reactions with air, it also reacts with the nitrogen (N2) in the air to form magnesium nitride (Mg3N2).3 Mg + N2 --> Mg3N2By adding water to the crucible containing the magnesium nitride, the magnesium nitride will become magnesium hydroxide. The ammonia gas produced will rise out of the crucible, eliminating the nitrogen.Mg3N2 + H2O --> 3Mg(OH)2 + 2NH3After heating the magnesium hydroxide, the product becomes just magnesium oxide.3Mg(OH)2 + heat --> MgO + H2OIn other words, when water is added, the nitrogen will react with the water, causing it to form ammonia and thus evaporating from the substance. This leaves behind the magnesium hydroxide, which becomes magnesium oxide and water after it is heated.
Why is 2 Mg O2 equals 2 MgO is not a combustion reaction?
The reaction 2 Mg + O2 -> 2 MgO is indeed a combustion reaction, where magnesium (Mg) reacts with oxygen (O2) to produce magnesium oxide (MgO). Combustion reactions are characterized by rapid reactions with oxygen, resulting in the release of energy in the form of heat and light. In this case, magnesium undergoes combustion to form magnesium oxide.
What type of chemical reaction is the burning of magnesium?

If magnesium and platinum are used to make a cell, what half-reactions will occur?
(For Mg2+(aq) + 2e- → Mg(s), E0 = 2.37 V and for Pt2+ (aq) + 2e- → Pt(s), E0 = 1.18 V)Pt2+(aq) + 2e- → Pt(s) and Mg(s) → Mg2+ (aq) + 2e-

Why is the burning of magnesium considered a chemical change?
During burning magnesium is transformed in magnesium oxide - a chemical reaction:2 Mg + O2 = 2 MgO
