Chemical Reactions Flashcard (1)

Front

What is a double replacement reaction?

Back

A chemical reaction where two ionic compounds exchange ions to form two new compounds.

Front

What is the Law of Conservation of Mass?

Back

A principle stating that mass is neither created nor destroyed in a chemical reaction; the total mass of reactants equals the total mass of products.

Front

How does surface area affect reaction rates?

Back

Increased surface area speeds up reactions by allowing more collisions between reactant particles.

Front

What is the first step in balancing a chemical equation?

Back

Writing the unbalanced equation.

Front

Which of the following is NOT a sign of a chemical reaction?

Back

Melting.

Front

What is a single replacement reaction?

Back

A chemical reaction where one element replaces another in a compound.

Front

What is a combustion reaction?

Back

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

Front

What is a decomposition reaction?

Back

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

Front

What are coefficients in a chemical equation?

Back

Numbers placed before compounds in a chemical equation to indicate the number of molecules or moles of each substance.

Front

What is the significance of balancing chemical equations?

Back

Balancing chemical equations ensures that the same number of each type of atom appears on both sides of the equation, adhering to the Law of Conservation of Mass.
