Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where one compound breaks down into two or more simpler products. Example: 2NaF ⟶ 2 Na + F₂.

Front

What must be true about the number of atoms in a chemical reaction?

Back

The number of atoms you begin with in a chemical reaction must be the same as the number of atoms you end with.

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: 2FeCl₃ + 3Zn ⟶ 2Fe + 3ZnCl₂.

Front

What are products in a chemical reaction?

Back

Products are the substances that are formed as a result of a chemical reaction, located to the right of the arrow in a chemical equation.

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: A + B ⟶ AB.

Front

What is a chemical equation?

Back

A chemical equation is a symbolic representation of a chemical reaction, showing the reactants and products along with their quantities.

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

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 reactant in a chemical reaction?

Back

Reactants are the starting substances in a chemical reaction, located to the left of the arrow in a chemical equation.

Front

What is an example of a combustion reaction?

Back

An example of a combustion reaction is: CH₄ + 2O₂ ⟶ CO₂ + 2H₂O.
