Balancing and Types of 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 is the first step in balancing a chemical equation?

Back

Identify the number of atoms of each element in the reactants and products.

Front

What does the coefficient in a chemical equation represent?

Back

The coefficient indicates the number of molecules or moles of a substance involved in the reaction.

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.

Front

What is a combustion reaction?

Back

A combustion reaction is a chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light and heat.

Front

What is the general form of a synthesis reaction?

Back

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

Front

What is a single replacement reaction?

Back

A single replacement reaction is a type of reaction where one element replaces another in a compound, represented as A + BC → AC + B.

Front

What is a double replacement reaction?

Back

A double replacement reaction involves the exchange of ions between two compounds, represented as AB + CD → AD + CB.

Front

How do you determine the type of reaction?

Back

To determine the type of reaction, analyze the reactants and products to see if they fit the definitions of synthesis, decomposition, single replacement, or double replacement.

Front

What is the significance of balancing chemical equations?

Back

Balancing chemical equations is crucial because it ensures that the law of conservation of mass is upheld, meaning matter is neither created nor destroyed.
