Unit 6: Chemical Equations and Reactions Fall 2024 Final Ex. Rev

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, reflecting 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

What is the Law of Conservation of Mass?

Back

It states that matter cannot be created or destroyed in a chemical 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

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 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 single displacement reaction?

Back

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

Front

What is a combustion reaction?

Back

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

Front

What is the significance of balancing chemical equations?

Back

Balancing chemical equations is important because it ensures that the Law of Conservation of Mass is upheld, showing that matter is neither created nor destroyed.

Front

What is the general form of a chemical equation?

Back

The general form of a chemical equation is: Reactants → Products.
