Single Replacement Reactions and Activity Series

The video tutorial covers the five types of chemical reactions, focusing on predicting reactions. It explains combination, decomposition, and single replacement reactions, emphasizing the use of the activity series to determine if reactions occur. Examples and practice problems are provided to reinforce understanding.

What is formed when a non-metal oxide reacts with water?

• An acid

• A metal

• A base

• A salt

In a decomposition reaction, what happens to the compound?

• It remains unchanged

• It forms a new compound

• It breaks down into its elements

• It combines with another compound

What is a single replacement reaction?

• When a compound breaks down into elements

• When two compounds exchange elements

• When one element replaces another in a compound

• When two elements combine to form a compound

What does the Activity Series help predict?

• The color of a compound

• The temperature of a reaction

• Whether a single replacement reaction will occur

• The speed of a reaction

Which element can replace another in a compound according to the Activity Series?

• A less active element can replace a more active one

• An element lower on the list can replace one higher

• A more active element can replace a less active one

• Any element can replace any other

In the Activity Series, which element is considered even though it's not a metal?

• Carbon

• Oxygen

• Hydrogen

• Nitrogen

What happens if iodine tries to replace bromine in sodium bromide according to the Activity Series?

• A new compound will form

• No reaction will occur

• Bromine will replace iodine

• Iodine will replace bromine

When calcium reacts with hydrochloric acid, what is the product?

• Calcium carbonate and carbon dioxide

• Calcium hydroxide and water

• Calcium chloride and hydrogen gas

• Calcium sulfate and oxygen

What is the correct formula for the product when aluminum bromide reacts with chlorine?

• AlCl

• AlCl4

• AlCl2

• AlCl3

What is the most common error when predicting products in single replacement reactions?

• Not applying formula writing rules

• Ignoring diatomic molecules

• Forgetting to balance the equation

• Not using the Activity Series
