To analyze the chemical reaction that produces elephant toothpaste, we can focus on the nature of reactants and products involved. Typically, this reaction produces oxygen gas and foam from the decomposition of hydrogen peroxide using yeast (which contains catalase that catalyzes the decomposition).
From this information, we can select the three statements that accurately compare the reactants and products:
1. **A. They have different physical and chemical properties.** - This is true as the reactants (like hydrogen peroxide) and products (like oxygen and water along with foam) exhibit different properties.
2. **C. They have the same total number of atoms.** - This is also true, as in a chemical reaction, the law of conservation of mass states that the total number of atoms remains the same before and after the reaction, though they may be arranged differently.
3. **F. The chemical elements in the reactant and in the products are the same.** - This is true, as the elements present in the reactants (like hydrogen and oxygen in hydrogen peroxide) are the same as those in the products (like water and oxygen).
Therefore, the correct statements are: **A, C,** and **F.**
