Types of Chemical Reactions

What is a Double Displacement Reaction?

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

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

• A reaction where two elements combine to form a compound.

• A reaction that involves the transfer of electrons between two species.

What is a Synthesis Reaction?

• A reaction where two or more simple substances combine to form a more complex substance.

• A reaction where a complex substance breaks down into simpler substances.

• A reaction that involves the exchange of ions between two compounds.

• A reaction that occurs only in the presence of a catalyst.

What is a Redox Reaction?

• A reaction that involves both reduction and oxidation processes. Example: 2Na + Cl₂ → 2NaCl.

• A reaction that only involves oxidation processes.

• A reaction that only involves reduction processes.

• A reaction that does not involve any electron transfer.

What is an Exothermic Reaction?

• A reaction that absorbs energy from its surroundings.

• A reaction that releases energy to its surroundings, usually in the form of heat.

• A reaction that occurs only in the presence of a catalyst.

• A reaction that results in a decrease in temperature.

What are Products?

• Substances that are formed as a result of a chemical reaction. They are found on the right side of a chemical equation.

• Elements that are combined to form a compound.

• The starting materials in a chemical reaction, found on the left side of a chemical equation.

• The energy released during a chemical reaction.

What is a Catalyst?

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

• A type of chemical that slows down reactions.

• A mixture of substances that cannot react with each other.

• A solid that can absorb liquids and gases.

What is the Law of Conservation of Mass?

• In a chemical reaction, mass is neither created nor destroyed; it is conserved.

• Mass can be created or destroyed in a chemical reaction.

• The total mass of products is always greater than the total mass of reactants.

• Mass is only conserved in physical changes, not in chemical reactions.

What are Reactants?

• Substances that undergo a chemical change in a reaction. They are found on the left side of a chemical equation.

• Substances that are produced as a result of a chemical reaction, found on the right side of a chemical equation.

• Elements that do not participate in a chemical reaction and remain unchanged.

• Compounds that can only exist in solid form and cannot be gases or liquids.

What is a Single Displacement Reaction?

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

• A reaction where two compounds exchange ions.

• A reaction that involves the combination of two elements to form a compound.

• A reaction that occurs only in the presence of a catalyst.

What is a Chemical Equation?

• A graphical representation of a chemical reaction.

• A symbolic representation of a chemical reaction, showing the reactants and products.

• A numerical representation of chemical quantities.

• A description of the physical state of reactants and products.
