Single Replacement Reactions

Which of the following correctly describes a single replacement reaction?

• two elements combine to form a compound

• oxygen is necessary for the reaction to occur

• elements from two compounds replace each other

• one element replaces another element in a compound

What do we look at to determine if an element is strong enough to replace another element in a single replacement reaction?

• Solubility Rules 
• Ionic Charges
• It must be insoluble!
• Activity Series

When using the activity series the more reactive metals are on top

• True

• False

Write the halogens in order from MOST active to LEAST active

• F, I Cl, Br

• Cl, F, Br, I

• F, Cl, Br, I

• I, Br, F, Cl

Which of the following explains why fluorine can not replace lithium?

• Fluorine is not as reactive as lithium

• Fluorine can only replace other Halogens, not metals

• Fluorine can replace lithium, but only when they are in water
