Balancing and reaction types

Front

What is a Single Replacement reaction?

Back

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

Front

What is a Reactant in a chemical equation?

Back

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

Front

How can you tell if a chemical equation is balanced?

Back

A chemical equation is balanced when the number of atoms of each element is the same on both sides of the equation.

Front

What is a Synthesis reaction?

Back

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

Front

What is a Decomposition reaction?

Back

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

Front

What is a Coefficient in a chemical equation?

Back

A number placed in front of a chemical formula to indicate how many molecules or moles of that substance are involved in the reaction.

Front

What is a Product in a chemical equation?

Back

A substance that is formed as a result of a chemical reaction, typically found on the right side of the equation.

Front

What is a Double Replacement reaction?

Back

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

Front

What is Combustion reaction?

Back

A reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat, typically producing CO2 and H2O.

Front

What does it mean for an equation to be unbalanced?

Back

An unbalanced equation has a different number of atoms for one or more elements on each side of the equation.
