Activity Series and Single Replacement Reactions

The video tutorial covers the concept of the activity series, a list of elements ranked by reactivity. It explains how metals and non-metals differ in reactivity, with metals losing electrons to become cations and non-metals gaining electrons to become anions. The activity series is used to predict single replacement reactions, where a more reactive element can replace a less reactive one in a compound. Several examples are provided, including reactions involving zinc, calcium, copper, and bromine, demonstrating how to use the activity series to determine if a reaction will occur.

What is the primary purpose of the activity series?

• To classify elements by their color

• To organize elements by their reactivity

• To rank elements by their atomic number

• To list elements alphabetically

In the activity series, what is the tendency of metals at the top of the list?

• They tend to lose electrons easily

• They form covalent bonds

• They tend to gain electrons easily

• They do not react with non-metals

How do non-metals at the top of the activity series behave?

• They form metallic bonds

• They lose electrons easily

• They gain electrons easily

• They do not participate in reactions

What determines if a single replacement reaction will occur?

• The position of elements in the activity series

• The color of the reactants

• The phase of the reactants

• The temperature of the reaction

In a single replacement reaction, what happens if the element is below the similar element in the compound?

• No reaction will occur

• The reaction will occur

• The compound will decompose

• The element will replace the compound

In the reaction between zinc and hydrochloric acid, why does the reaction occur?

• Zinc is below hydrogen in the activity series

• Zinc is above hydrogen in the activity series

• Hydrochloric acid is a strong acid

• Zinc is a noble gas

What is the product when zinc reacts with hydrochloric acid?

• Zinc nitrate and nitrogen gas

• Zinc chloride and hydrogen gas

• Zinc sulfate and oxygen

• Zinc oxide and water

In the reaction between calcium and lead nitrate, why does calcium replace lead?

• Calcium is a noble gas

• Lead is a non-metal

• Calcium is above lead in the activity series

• Calcium is below lead in the activity series

What happens in the reaction between copper and lithium sulfate?

• Copper forms a complex ion

• No reaction occurs

• Lithium replaces copper

• Copper replaces lithium

Why does no reaction occur between bromine and iron(II) chloride?

• Chlorine is a metal

• Bromine is above chlorine in the activity series

• Bromine is below chlorine in the activity series

• Iron is a noble gas
