GCSE Chemistry - Reactivity Series of Metals & Displacement Reactions #37

The video tutorial explains the reactivity series of metals, detailing how metals react with acids and water. It covers the electron arrangement in metals, which influences their reactivity, and describes how more reactive metals can displace less reactive ones in displacement reactions. The tutorial also discusses the importance of fair testing conditions when comparing metal reactivity.

What is the main factor that determines the reactivity of a metal?

• The ease of losing outer shell electrons

• The number of protons in the nucleus

• The color of the metal

• The density of the metal

Which of the following metals would react most violently with hydrochloric acid?

• Potassium

• Copper

• Iron

• Zinc

Why is it important to ensure the same mass and surface area of metal samples in reactivity tests?

• To make the experiment more interesting

• To ensure the test is fair and results are comparable

• To save on materials

• To make the reaction faster

What products are formed when lithium reacts with water?

• Lithium chloride and water

• Lithium hydroxide and hydrogen

• Lithium hydroxide and oxygen

• Lithium oxide and hydrogen

In a displacement reaction, what happens when magnesium is added to iron sulphate solution?

• Magnesium and iron form an alloy

• No reaction occurs

• Iron displaces magnesium, forming iron sulphate

• Magnesium displaces iron, forming magnesium sulphate
