Answer 2

Explanation:

a) When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide. A compound is a material in which atoms of different elements are bonded to one another. Oxygen and magnesium combine in a chemical reaction to form this compound.

b) Sulphur dioxide can dissolve in water to form Sulfurous acid(H2SO3).

c) Here, Zinc reacts with Copper sulphate solution to form colourless zincsulphate and solid copper in deposited form. c) Ag + CuSO4 ==> No reaction. Here, Silver metal is less reactive than copper therefore reaction did not took place.
