What are the general characteristics that help you recognize single-replacement reactions?

• Single-replacement reactions involve two compounds reacting with each other.
• Single-replacement reactions always produce a gas as a product.
• Single-replacement reactions require heat to occur.
• Single-replacement reactions involve an element displacing another in a compound.

What are the general characteristics that help you recognize double-replacement reactions?

• Double-replacement reactions always produce a solid product.
• These reactions involve the combination of two gases only.
• Double-replacement reactions do not involve any ion exchange.
• Double-replacement reactions involve the exchange of ions between two compounds, often resulting in a precipitate, gas, or water.
