• K₂C₂H₃O₂
• PC₂H₃O₂
• PC₂H₃O₂

Which response includes only synthesis reactions?

• II and III only
• I only
• II only
• I and IV only

Identify the type of the reaction
CaO + H₂O → Ca(OH)₂

• synthesis
• decomposition
• single replacement
• combustion

Which reaction is both a redox and a decomposition reaction?

• I and II only
• I only
• III only
• II only

A chemical reaction in which a complex substance breaks down into two or more simpler substances is a

• synthesis reaction.
• double-replacement reaction.
• single-replacement reaction.
• decomposition.

What would be the products for the single replacement reaction:
F₂ + LiBr →
(Just identify the correct formulas for the products for the reaction. You do not need to balance the equation.)

• FBr + Li⁺
• Br₂ + LiF
• No reaction would occur.
• Br⁻ + Li⁺
