Balancing and Classifying Reactions

Front

What is a balanced chemical equation?

Back

A balanced chemical equation has equal numbers of each type of atom on both sides of the equation, following the law of conservation of mass.

Front

What are coefficients in a chemical equation?

Back

Coefficients are the numbers placed in front of compounds in a chemical equation to indicate the number of molecules or moles of that substance.

Front

How do you balance a chemical equation?

Back

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

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.

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 the general form of a combustion reaction?

Back

A combustion reaction generally involves a hydrocarbon reacting with oxygen to produce carbon dioxide and water.

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.

Front

What is the difference between a reactant and a product?

Back

Reactants are substances that undergo a chemical change, while products are the substances formed as a result of that change.

Front

What is the significance of balancing chemical equations?

Back

Balancing chemical equations is important to accurately represent the quantities of reactants and products involved in a reaction.

Front

What is an example of a synthesis reaction?

Back

An example of a synthesis reaction is 2H₂ + O₂ → 2H₂O, where hydrogen and oxygen combine to form water.
