Types of Chemical Reactions Flashcard #1

Front

What is a Decomposition Reaction?

Back

A chemical reaction where one compound breaks down into two or more simpler products. Example: Pb(NO3)2 → PbO + NO2 + O2.

Front

What are Reactants in a chemical equation?

Back

The substances that undergo a chemical change in a reaction, found on the left side of the equation. Example: In H2 + O → H2O, H2 and O are reactants.

Front

Define Single Replacement Reaction.

Back

A type of reaction where one element replaces another in a compound. Example: A + BC → AC + B.

Front

What is a Net Ionic Equation?

Back

An equation that shows only the particles that participate in the reaction, omitting spectator ions. Example: Ba2+(aq) + SO4^2-(aq) → BaSO4(s).

Front

How do you balance a chemical equation?

Back

By ensuring the number of atoms for each element is the same on both sides of the equation. Example: CH4 + 2O2 → CO2 + 2H2O is balanced.

Front

What is a Synthesis Reaction?

Back

A reaction where two or more substances combine to form a single product. Example: A + B → AB.

Front

What is a Combustion Reaction?

Back

A reaction that involves the burning of a substance in the presence of oxygen, producing heat and light. Example: CH4 + 2O2 → CO2 + 2H2O.

Front

What is a Double Replacement Reaction?

Back

A reaction where two compounds exchange ions to form two new compounds. Example: AB + CD → AD + CB.

Front

What is the significance of the coefficients in a balanced equation?

Back

Coefficients indicate the number of moles of each substance involved in the reaction, ensuring mass conservation.

Front

What is the role of a catalyst in a chemical reaction?

Back

A substance that increases the rate of a reaction without being consumed in the process.
