Chemical Reactions: Single Replacement

Imagine Daniel, Oliver, and Ethan are in a chemistry lab. They come across a term 'activity series'. What do you think the activity series in chemistry is?

• Is it a list of non-metals arranged in order of their reactivity, which Daniel might use to decide which non-metal to react with?

• Or is it a list of metals and hydrogen arranged in order of their reactivity, which Oliver might use to decide which metal to react with?

• Could it be a list of compounds arranged in order of their solubility, which Ethan might use to decide which compound to dissolve?

• Or is it simply a list of elements arranged in alphabetical order, which they might use to quickly find an element?

Imagine Harper, Samuel, and Nora are in a science lab. They are experimenting with different metals and compounds. Suddenly, they stumble upon a reaction. Can you guess what it is? What is a metal displacement reaction?

• Is it a chemical reaction where two metals combine to form a new compound, just like Harper suggested?

• Or is it a chemical reaction where a less reactive metal displaces a more reactive metal from its compound, as Samuel thought?

• Could it be a physical reaction where a metal changes its shape or size, like Nora's guess?

• Or is it a chemical reaction where a more reactive metal displaces a less reactive metal from its compound, which none of them thought of?

Ethan, Lily, and Anika are having a science competition! They are trying to figure out which metal will displace copper from copper sulfate. Can you help them out?

• Is it lead, mercury, or cadmium?

• Could it be iron, nickel, or cobalt?

• Or is it aluminum, magnesium, or zinc?

• Maybe it's silver, gold, or platinum?

Imagine Olivia, Jackson, and Emma are in a chemistry lab. They come across a term 'activity series'. They start wondering, what could be the purpose of an activity series in predicting products in chemical reactions? Can you help them out?

• Is it to determine the rate of chemical reactions?

• Or, is it to balance chemical equations?

• Maybe, it's to predict products in chemical reactions?

• Or, could it be to measure the temperature of chemical reactions?

Abigail, Luna, and Benjamin are having a science debate! They're discussing what happens during a metal displacement reaction. Can you help them settle the debate?

• Abigail thinks a less reactive metal displaces a more reactive metal from its compound.

• Luna believes the metals combine to form a new compound.

• Benjamin suggests that no reaction occurs.

• Or, is it that a more reactive metal displaces a less reactive metal from its compound?

Imagine Olivia, Ethan, and Maya are superheroes. Olivia has a shield made of copper, Ethan has one made of iron, and Maya has one made of zinc. Whose shield would react more when exposed to certain substances?

• Olivia's copper shield

• Ethan's iron shield

• They all react the same

• Maya's zinc shield

Imagine Nora, Olivia, and Grace are in a science lab. Nora has a piece of Metal A and Olivia has Metal B's compound. If Nora combines her Metal A with Olivia's Metal B's compound, what would be the result of this metal displacement reaction?

• Metal A + Metal B's compound -> Metal A + Metal B's compound

• Metal A + Metal B's compound -> Metal B + Metal A's compound

• Metal A + Metal B -> Metal B + Metal A

• Metal A + Metal B -> Metal A + Metal B

Imagine Benjamin, Isla, and Noah are in a science lab. They have a solution of silver nitrate and they are given aluminum, iron, copper, and gold. Which metal will Noah use to displace silver from the silver nitrate solution?

• aluminum

• iron

• copper

• gold

Nora, Isla, and William are having a debate in their chemistry class. They are discussing why an activity series is important in chemistry. Can you help them settle the debate?

• Nora thinks an activity series is important in chemistry because it determines the color of a substance.

• Isla argues that an activity series is important in chemistry because it helps predict the reactivity of metals and their ability to displace other metals in a chemical reaction.

• William believes an activity series is important in chemistry because it helps balance chemical equations.

• Or is it important because it measures the acidity of a solution?
