Magnesium ribbon emits white flames as it burns, and the resulting white powder is magnesium oxide. The reaction between magnesium and oxide is what causes it to form. Magnesium hydroxide is created when magnesium oxide is applied to wet watch glass, or (magnesium oxides + water).

Answer – A student while burning a magnesium ribbon in air collected the products in a wet watch glass. The new product obtained was magnesium hydroxide.

Magnesium oxide is created during the burning of magnesium metal when it combines with airborne oxygen. A compound is a substance made up of atoms from various elements that are chemically linked to one another. This molecule is created by the chemical interaction between oxygen and magnesium. It turns into a white powder of magnesium oxide after burning. Magnesium creates this powder by transferring two electrons to oxygen atoms. This is a combination reaction that is also exothermic.
The required reaction is listed below:

MgO + H2O —> Mg(OH)2

here, MgO – Magnesium oxide

H2O – water

Mg(OH)2 – magnesium hydroxide.
