Reaction Review Matter

Front

What is a Single Replacement reaction?

Back

A reaction where one element replaces another in a compound, represented by the general formula A + CD → C + AD.

Front

What is a Combination reaction?

Back

A reaction where two or more substances combine to form a single product, represented by the general formula A + B → AB.

Front

What does the principle of conservation of mass state?

Back

Matter is not created or destroyed in a chemical reaction; the total mass of reactants equals the total mass of products.

Front

What are coefficients in a chemical equation?

Back

Large numbers placed before a chemical formula to indicate the number of molecules or moles of that substance.

Front

Identify the reactants in the equation: 2Mg + O₂ → 2MgO.

Back

The reactants are Mg (magnesium) and O₂ (oxygen).

Front

What is a Decomposition reaction?

Back

A reaction where a single compound breaks down into two or more simpler products, represented by the general formula AB → A + B.

Front

What is a Double Replacement reaction?

Back

A reaction where two compounds exchange ions or bonds to form two new compounds, represented by the general formula AB + CD → AD + CB.

Front

What is a Combustion reaction?

Back

A reaction that involves the burning of a substance in the presence of oxygen, typically producing carbon dioxide and water.

Front

What is the difference between reactants and products?

Back

Reactants are the starting substances in a chemical reaction, while products are the substances formed as a result of the reaction.

Front

What is a chemical equation?

Back

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