Balancing Equations and Predicting Products

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, reflecting the law of conservation of mass.

Front

What is the purpose of balancing chemical equations?

Back

The purpose is to ensure that the same number of atoms of each element is present on both sides of the equation, which is necessary for the reaction to obey the law of conservation of mass.

Front

What are reactants in a chemical reaction?

Back

Reactants are the starting substances that undergo a chemical change in a reaction.

Front

What are products in a chemical reaction?

Back

Products are the substances formed as a result of a chemical 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 chemical reaction where one element replaces another in a compound.

Front

What is a double replacement reaction?

Back

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

Front

How do you determine the coefficients in a balanced equation?

Back

Coefficients are determined by adjusting the numbers in front of the compounds to ensure that the number of atoms for each element is equal on both sides of the equation.

Front

What is the general form of a synthesis reaction?

Back

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