The aqueous solution of X changes _________.

Q.

What is the name of the compound when Magnesium burns with a bright white light resulting in a chemical reaction.

Q.

What is a redox reaction ? When a magnesium ribbon burns in air with a dazzling flame and forms a white ash, is magnesium oxidised or reduced ?

Q. A silvery-white metal X taken in the form of ribbon, when ignited, burns in air with a dazzling white flame to form a white powder Y. When water is added to powder Y, it dissolves partially to form another substance Z.

(b) What is powder Y?
(c) With which substance metal X combines to form powder Y?
(d) What is substance Z? Name one domestic use of substance Z.
(e) Write a balanced chemical equation of the reaction which takes place when metal X burns in air to form powder Y.

Q. A magnesium ribbon is burnt in oxygen to give a white compound $X$ accompanied by the emission of light. If the burning ribbon is now placed in an atmosphere of nitrogen, it continues to burn and forms a compound $Y$. Write the chemical formula of $X$ and $Y$:
