The independent variable in the Magnesium Oxide Lab would be the Mass of the Magnesium Ribbon. This is because the mass of the product, i.e. Magnesium Oxide, depends on how much Magnesium is added.
Magnesium + copper oxide --> magnesium oxide + copper
The reaction between magnesium and oxygen to form magnesium oxide is a chemical reaction called a combustion reaction. In this type of reaction, a substance (such as magnesium) reacts with oxygen to produce heat and light.
Zinc oxide reacts with metallic magnesium to produce magnesium oxide and metallic zinc.
Magnesium is the metal which reacts with oxygen to form magnesium oxide.
Magnesium oxide forms when magnesium metal reacts with oxygen gas to produce magnesium oxide. The chemical equation for this reaction is 2Mg + O2 -> 2MgO.
Magnesium + copper oxide --> magnesium oxide + copper
The reaction between magnesium and oxygen to form magnesium oxide is a chemical reaction called a combustion reaction. In this type of reaction, a substance (such as magnesium) reacts with oxygen to produce heat and light.
Zinc oxide reacts with metallic magnesium to produce magnesium oxide and metallic zinc.
The reaction between iron oxide powder and magnesium powder is exothermic and produces iron and magnesium oxide. The magnesium metal displaces the iron from the iron oxide, resulting in a single displacement reaction. The reaction also produces a significant amount of heat due to the exothermic nature of the reaction.
When you heat iron oxide powder with magnesium powder, a chemical reaction takes place where the magnesium reacts with the oxygen in the iron oxide to produce iron metal and magnesium oxide. This is a type of redox reaction where reduction and oxidation occur simultaneously.
Magnesium is the metal which reacts with oxygen to form magnesium oxide.
Magnesium oxide forms when magnesium metal reacts with oxygen gas to produce magnesium oxide. The chemical equation for this reaction is 2Mg + O2 -> 2MgO.
Magnesium Oxide is a compound, not a reaction. However if you are talking about making magnesium oxide from its individual elements, that would be a redox reaction. In this reaction, magnesium is going from a zero oxidation state to a +2 oxidation state. If you think of the acronym OIL RIG (Oxidation Is Lost Reduction Is Gained) Magnesium is being oxidized as it has lost two electrons. As well, the oxygen is gaining two electrons to have a -2 charge and is therefore being reduced hence the term redox.
When magnesium reacts with air, it forms magnesium oxide. This process is a combustion reaction whereby magnesium burns in the presence of oxygen to produce magnesium oxide and heat. The magnesium metal reacts with oxygen from the air to form a layer of magnesium oxide on its surface.
magnesium oxide + nitrogen >>> magnesium nitrite
When a sparkler is lit, the reaction involves the combustion of the metal fuel and the oxidation of the metal. For example, a common reaction in sparklers involves the combustion of magnesium with oxygen to produce magnesium oxide and light and heat energy. The word equation for this reaction is: Magnesium + Oxygen → Magnesium Oxide + Light + Heat.
When magnesium ribbon is burned in air, it forms magnesium oxide. This is a white powdery substance that results from the reaction of magnesium with oxygen in the air.
