A geologist identifies the identical index fossils in rock layers from 2 different areas. What can be concluded?

• The deposition rate of the 2 layers was identical

• The fossil organism evolved independently in the 2 separate layers

• The two rock layers were deposited at approximately the same time.

• The index fossils will also occur in sediment deposited on top of these layers.

This is a chemical reaction for the decomposition of carbonic acid into water and carbon dioxide. How does this reaction support the Law of Conservation of Mass?

• Several molecules of water are produced.

• The mass of carbon atoms is reduced during the reaction.

• The mass of the atoms in the reactant equals the mass of the atoms in the products.

• The mass of hydrogen atoms is the only thing that remains the same before and after the reaction.

Which statement is true about a chemical reaction?

• The physical states of the atoms in the reactants determine the products.

• Some of the atoms in the reactants will be a part of the products.

• The number of atoms in the reactants determines the products.

• All of the atoms in the reactants will be a part of the products.
