(c) Displacement reaction (d) Double displacement reaction​

Answer 1

Combination Reaction...

Answer 2

ANSWER:

(a) Combination reaction

Burning magnesium ribbon in air to form magnesium oxide is an example of combination reaction. When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide. Oxygen and magnesium combine in a chemical reaction to form this compound. After it burns, it forms a white powder of the magnesium oxide. Magnesium gives up two electrons to oxygen atoms to form this powdery product.
