Question

A. Magnesium burns in air experiment.
1.name two compounds formed when magnesium burns in air.
2.why n how are these compounds formed?
3.if u add water to the mixture of the compounds formed, what will be the products formed n what will be the nature of the solution obtained?
^_^Answer clearly PLZ

Answer 1

1. Magnesium Oxide ( 97%) and Magnesium Carbonate ( 3%).

2. When Magnesium element is burned in air, a chemical reaction takes place, most of the magnesium reacts with oxygen to form Magnesium oxide and some of the magnesium oxide reacts with the Carbon Dioxide in air to form Magnesium Carbonate.

3. Magnesium oxide reacts with water to form Magnesium Hydroxide which is basic in nature and Magnesium Carbonate reacts with water to form a neutral solution, as the percentage of Magnesium Hydroxide is greater in the solution so the solution is basic.


I hope this will help you.
