Reactivity of Metals and Reactions

This video tutorial explores the reactivity series of metals, explaining how metals react with acids and water. It discusses the electron arrangement in metals and how it influences their reactivity, forming positive ions. The video also covers displacement reactions, where more reactive metals displace less reactive ones. Practical examples, such as reactions with hydrochloric acid and water, illustrate these concepts. The tutorial concludes with a summary and a call to action for viewers to like and subscribe.

What do all metals have in common regarding their electron arrangement?

• They have no electrons in the outer shell.

• They have a full outer shell.

• They have more protons than electrons.

• They have electrons in the outermost shell they want to get rid of.

Which group of metals is the most reactive?

• Group 1 metals

• Group 2 metals

• Noble gases

• Transition metals

What is formed when a metal reacts with an acid?

• Metal oxide and water

• Salt and water

• Salt and hydrogen gas

• Metal hydroxide and oxygen

What happens when potassium reacts with hydrochloric acid?

• It forms potassium sulfate and oxygen.

• It forms potassium chloride and hydrogen, reacting explosively.

• It forms potassium nitrate and nitrogen.

• It forms potassium oxide and water.

How can we measure the reactivity of metals with acids?

• By checking the pH level.

• By weighing the metal before and after the reaction.

• By observing the color change.

• By measuring the temperature change.

What do metals form when they react with water?

• Metal carbonates and oxygen

• Metal oxides and hydrogen

• Metal hydroxides and hydrogen

• Metal sulfates and water

Which metals are reactive enough to react with water?

• Only transition metals

• All metals

• Only the most reactive metals

• Zinc, iron, and copper

What is a displacement reaction?

• A reaction where a metal reacts with oxygen.

• A reaction where a metal forms a compound with water.

• A reaction where a more reactive metal displaces a less reactive one.

• A reaction where a metal forms a salt with an acid.

What happens when magnesium is added to a solution of iron sulfate?

• Magnesium does not react.

• Magnesium forms a compound with water.

• Magnesium forms a salt with the sulfate.

• Magnesium displaces iron to form magnesium sulfate.

Why does copper not displace iron from iron sulfate?

• Copper is more reactive than iron.

• Copper is less reactive than iron.

• Copper forms a different compound.

• Copper does not react with sulfates.
