M4 Review: Chemical Reactions (Chem)

Front

What is a chemical reaction?

Back

A process in which substances (reactants) undergo a transformation to form new substances (products).

Front

What are reactants in a chemical equation?

Back

The starting substances that undergo a chemical change in a reaction.

Front

What are products in a chemical equation?

Back

The substances that are formed as a result of a chemical reaction.

Front

What does a balanced chemical equation represent?

Back

It shows that the number of atoms for each element is the same on both sides of the equation, indicating the conservation of mass.

Front

What is a single replacement reaction?

Back

A reaction where one element replaces another in a compound.

Front

What is a double replacement reaction?

Back

A reaction where two compounds exchange ions or bonds to form two new compounds.

Front

What is a precipitate?

Back

A solid that forms and settles out of a liquid mixture during a chemical reaction.

Front

What is the law of conservation of mass?

Back

In a chemical reaction, mass is neither created nor destroyed; it remains constant.

Front

What is the significance of coefficients in a balanced equation?

Back

Coefficients indicate the number of molecules or moles of each reactant and product involved in the reaction.

Front

What is the role of catalysts in chemical reactions?

Back

Catalysts speed up chemical reactions without being consumed in the process.
