Flashcard: Types of Chemical Reactions and Balancing Equations

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more simple substances combine to form a more complex product. Example: A + B → AB.

Front

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: AB + CD → AD + CB.

Front

What is a product in a chemical reaction?

Back

A product is a substance that is formed as the result of a chemical reaction.

Front

How do you balance the equation 2Li + Cl2 → LiCl?

Back

The balanced equation is 2Li + Cl2 → 2LiCl.

Front

What are common signs of a chemical change?

Back

Common signs of a chemical change include a change in color, the production of gas (bubbling), and a change in temperature.

Front

What is a reactant in a chemical reaction?

Back

A reactant is a substance that undergoes change during a chemical reaction.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where a single compound breaks down into two or more simpler products. Example: AB → A + B.

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction; the mass of the reactants equals the mass of the products.

Front

What is an example of a combustion reaction?

Back

An example of a combustion reaction is the burning of methane: CH4 + 2O2 → CO2 + 2H2O.

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs heat from its surroundings.
