Balancing Equations and Reaction Types

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 synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more simple substances combine to form a more complex product.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where a single compound breaks down into two or more simpler products.

Front

What is a single replacement reaction?

Back

A single replacement reaction is a type of reaction where one element replaces another element in a compound.

Front

What is a double replacement reaction?

Back

A double replacement reaction is a type of reaction where the anions and cations of two different compounds exchange places, forming two new compounds.

Front

What is combustion?

Back

Combustion is a chemical reaction that occurs when a substance reacts rapidly with oxygen, producing heat and light.

Front

How do you identify a decomposition reaction?

Back

A decomposition reaction can be identified by the presence of a single reactant that breaks down into two or more products.

Front

What is the general form of a synthesis reaction?

Back

A + B → AB, where A and B are reactants that combine to form product AB.
