CP Chem. Balancing & Classifying Equations Practice

Front

What is a balanced chemical equation?

Back

A balanced chemical equation has the same number of each type of atom on both sides of the equation, indicating that mass is conserved during the reaction.

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 involved in the reaction.

Front

How do you determine if a chemical equation is balanced?

Back

Count the number of atoms of each element on both sides of the equation. If they are equal, the equation is balanced.

Front

What is the purpose of balancing chemical equations?

Back

Balancing chemical equations ensures that the law of conservation of mass is obeyed, meaning that matter is neither created nor destroyed in a chemical reaction.

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 it mean to classify a chemical reaction?

Back

Classifying a chemical reaction involves identifying the type of reaction, such as synthesis, decomposition, single replacement, or double replacement.

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 element 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.
