Types of Chemical Reactions

What is decomposition?

• Breaking substances apart.

• Combining substances together.

• Changing the state of matter.

• Creating new substances.

What is a product in a chemical reaction?

• A substance that is formed as a result of a chemical reaction.

• A substance that is consumed during a chemical reaction.

• A catalyst that speeds up the reaction.

• A mixture of reactants before the reaction occurs.

Mass cannot be ____ or ____.

• Created, destroyed

• Transformed, altered

• Increased, decreased

• Measured, observed

What is the general form of a synthesis reaction?

• A + B → AB

• A + B → A + B

• AB → A + B

• A + B + C → AB + C

What is a combustion reaction?

• A reaction that involves the burning of a substance in the presence of oxygen.

• A reaction that absorbs heat and does not produce light.

• A reaction that occurs without the presence of oxygen.

• A reaction that produces a gas without any heat change.

How can a decomposition reaction be represented?

• AB + C → A + B + C

• AB → A + B

• A + B → AB

• A + B + C → AB

What is an example of a decomposition reaction?

• 2H2O → 2H2 + O2

• H2 + O2 → 2H2O

• C6H12O6 → 2C2H5OH + 2CO2

• NaCl → Na + Cl2

What is a substance that is formed as the result of a chemical reaction?

• Reactant

• Catalyst

• Product

• Solvent

What is a single replacement 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 breaks down a compound into its individual elements.

What is a synthesis reaction?

• A reaction where two or more substances combine to form a single product.

• A reaction that breaks down a compound into simpler substances.

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

• A reaction that occurs without any change in the chemical composition.
