Reactivity of Metals and Reactions

The video tutorial explains the concept of reactivity, focusing on how different metals react with water and acids. It introduces the reactivity series, highlighting the varying reactivity levels of metals like gold, silver, iron, and Group One metals. The tutorial also covers how to write chemical equations for these reactions, providing examples and encouraging practice through questions.

Why are gold and silver commonly used in jewelry?

• They are not reactive with water.

• They are the most reactive metals.

• They react quickly with acids.

• They are very reactive with water.

What happens when Group 1 metals react with water?

• They only react with steam.

• They react instantly with visible effects.

• They react slowly over months.

• They do not react at all.

Which metal is at the top of the reactivity series?

• Gold

• Potassium

• Copper

• Iron

What is a common observation when calcium reacts with dilute acids?

• It explodes violently.

• There is a lot of fizzing.

• It turns into a gas.

• No reaction occurs.

Which metals do not react with dilute acids?

• Potassium, Sodium, and Lithium

• Tin, Lead, and Copper

• Copper, Silver, and Gold

• Calcium, Magnesium, and Iron

What is formed when metals react with cold water?

• Metal oxides and hydrogen gas

• Metal chlorides and oxygen gas

• Metal sulfates and carbon dioxide
