types of reactions

Front

What is a single displacement reaction?

Back

A reaction where one element replaces another in a compound, represented by the equation A + BC → AC + B.

Front

What is a reactant in a chemical equation?

Back

A substance that undergoes change during a chemical reaction, found on the left side of the equation.

Front

What is a synthesis (combination) reaction?

Back

A type of reaction where two or more reactants combine to form a single product, represented by the equation A + B → AB.

Front

What is a decomposition reaction?

Back

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

Front

What is the equation for a combustion reaction?

Back

A reaction that typically involves a hydrocarbon reacting with oxygen to produce carbon dioxide and water, represented by the equation C_xH_y + O_2 → CO_2 + H_2O.

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 equation AB + CD → AD + CB.

Front

What is the law of conservation of mass?

Back

In a chemical reaction, mass is neither created nor destroyed; the total mass of reactants equals the total mass of products.

Front

What is an example of a synthesis reaction?

Back

The reaction of silicon (Si) with sulfur (S8) to form silicon disulfide (Si2S4).

Front

What is an example of a decomposition reaction?

Back

The breakdown of aluminum hydroxide (Al(OH)3) into aluminum oxide (Al2O3) and water (H2O).

Front

What is the role of a catalyst in a chemical reaction?

Back

A substance that increases the rate of a chemical reaction without being consumed in the process.
