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 reactants combine to form a single product. Example: 2H₂ + O₂ → 2H₂O.

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: 2H₂O → 2H₂ + O₂.

Front

What is a single displacement reaction?

Back

A single displacement reaction is a type of chemical reaction where one element replaces another in a compound. Example: Zn + CuSO₄ → ZnSO₄ + Cu.

Front

What is a double displacement reaction?

Back

A double displacement reaction is a type of chemical reaction where two compounds exchange ions to form two new compounds. Example: AgNO₃ + NaCl → AgCl + NaNO₃.

Front

What are reactants in a chemical reaction?

Back

Reactants are the starting materials in a chemical reaction that undergo change to form products.

Front

What are products in a chemical reaction?

Back

Products are the substances that are formed as a result of a chemical reaction.

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 total mass of reactants equals the total mass of products.

Front

How do you balance a chemical equation?

Back

To balance a chemical equation, adjust the coefficients of the reactants and products to ensure that the number of atoms of each element is the same on both sides.

Front

What is the significance of coefficients in a balanced equation?

Back

Coefficients indicate the number of moles of each substance involved in the reaction and are used to balance the equation.

Front

What is an example of a common sign of a chemical change?

Back

A common sign of a chemical change is when a chemical has turned a different color, bubbled, or changed temperature.
