Types of Chemical Reactions

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more reactants combine to form a single product. Example: 2Na + Cl2 -> 2NaCl.

What is a double replacement reaction?

Back

A double replacement reaction is a type of chemical reaction where two compounds exchange ions or bonds to form two new compounds. Example: AgF + CaCl2 -> AgCl + CaF2.

Front

What characterizes a decomposition reaction?

Back

A decomposition reaction is characterized by a single reactant breaking down into two or more products. Example: 2H2O -> 2H2 + O2.

Front

What is a single replacement reaction?

Back

A single replacement reaction is a type of chemical reaction where one element replaces another in a compound. Example: Cl2 + 2KI -> I2 + 2KCl.

Front

What is the general form of a synthesis reaction?

Back

The general form of a synthesis reaction is A + B -> AB, where A and B are reactants that combine to form a product AB.

Front

What is the general form of a double replacement reaction?

Back

The general form of a double replacement reaction is AB + CD -> AD + CB, where two compounds exchange components.

Front

What is the general form of a decomposition reaction?

Back

The general form of a decomposition reaction is AB -> A + B, where a single compound breaks down into its components.

Front

What is the general form of a single replacement reaction?

Back

The general form of a single replacement reaction is A + BC -> AC + B, where element A replaces element B in compound BC.

Front

What are the signs that a chemical reaction has occurred?

Back

Signs of a chemical reaction include color change, temperature change, gas production, formation of a precipitate, and change in odor.

What is the role of energy in chemical reactions?

Back

Energy is required to break bonds in reactants and is released when new bonds form in products. Reactions can be exothermic (release energy) or endothermic (absorb energy).
