Chemical Reactions of Magnesium Ribbon
Magnesium is a highly reactive metal that easily reacts with atmospheric oxygen to form magnesium oxide. When a magnesium ribbon is burnt in oxygen, the reaction produces a bright white compound called magnesium oxide (x), accompanied by the emission of light.
a. Chemical Formula of x and y
Magnesium oxide is a white crystalline solid with the chemical formula MgO. The formation of magnesium oxide can be represented by the following equation:
2Mg(s) + O2(g) → 2MgO(s)
When the magnesium ribbon is placed in an atmosphere of nitrogen after burning, it continues to burn and produces a new compound called magnesium nitride (y). The chemical formula for magnesium nitride is Mg3N2. The reaction can be represented as follows:
3Mg(s) + N2(g) → Mg3N2(s)
b. Balance Equation when x is Dissolved in Water
When magnesium oxide (x) is dissolved in water, it reacts with water molecules to form magnesium hydroxide (Mg(OH)2). The balanced equation for this reaction is:
MgO(s) + H2O(l) → Mg(OH)2(aq)
The reaction is an example of a base reacting with water to form a metal hydroxide. Magnesium hydroxide is a white, insoluble solid that is commonly used in antacids and laxatives.
In conclusion, the chemical reactions of magnesium ribbon with oxygen and nitrogen produce magnesium oxide and magnesium nitride, respectively. When magnesium oxide is dissolved in water, it forms magnesium hydroxide. These reactions demonstrate the reactivity of magnesium and its ability to form different compounds depending on the conditions in which it is placed.
