Reactivity Series and Metal Displacement

The video tutorial explains the properties and reactivity of metals, highlighting the reactivity series, which ranks metals by their reactivity. It discusses single displacement reactions, where a more reactive metal displaces a less reactive one in a compound. The tutorial also covers the reactivity of metals with acids and the extraction of metals from ores, using examples like zinc and copper reactions. The reactivity series is crucial for predicting reactions and extracting valuable metals.

Which of the following metals is known for being very unreactive?

• Copper

• Zinc

• Gold

• Potassium

What is the primary purpose of the reactivity series?

• To predict the occurrence of single displacement reactions

• To determine the color of metals

• To classify metals based on their weight

• To measure the hardness of metals

In a single displacement reaction, which element can displace another?

• A more reactive element

• Any element

• An element of the same reactivity

• A less reactive element

What happens when zinc is added to copper sulfate solution?

• Copper metal deposits on zinc

• Zinc dissolves completely

• No reaction occurs

• The solution remains blue

Which metal can displace silver from silver nitrate?

• Platinum

• Gold

• Copper

• Magnesium

Why are hydrogen and carbon included in the reactivity series?

• To compare their reactivity with metals

• To determine their color

• To measure their density

• To classify them as metals

Which metal will not react with hydrochloric acid due to its position in the reactivity series?

• Copper

• Platinum

• Zinc

• Magnesium

What is the main component of malachite used in copper extraction?

• Copper sulfate

• Copper nitrate

• Copper carbonate

• Copper oxide

What role does carbon play in the extraction of copper from copper oxide?

• It dissolves the copper

• It oxidizes the copper

• It forms a compound with copper

• It acts as a reducing agent

What does the reactivity series help predict in terms of metal extraction?

• The melting point of the metal

• Whether a metal can be extracted from its ore

• The weight of the extracted metal

• The color of the extracted metal
