### 1. How Does the Rearrangement of Atoms Happen? The rearrangement of atoms occurs during a **chemical reaction**. In a chemical reaction, the atoms in the reactant substances are **broken apart** and then **reorganized** to form new products. This process involves making and breaking **chemical bonds** between atoms. For example, when hydrogen gas reacts with oxygen gas to form water, the hydrogen and oxygen atoms rearrange to create water molecules. **Key Points:** - **Breaking Bonds:** Existing chemical bonds in the reactants are broken. - **Forming Bonds:** New chemical bonds are formed to create different substances. - **Conservation of Atoms:** The total number of each type of atom remains the same before and after the reaction. ### 2. Analysis of the Bubbling Mixture **Scenario:** A clear liquid and a white powder are added to a beaker on a hot plate. The mixture instantly begins to bubble. Someone concludes that a chemical reaction has occurred. **Do You Agree with This Conclusion? Why or Why Not?** **Answer:** **Partially Agree** **Reasoning:** - **Bubbling Indicates Gas Formation:** Bubbling often suggests that a gas is being produced, which can be a sign of a chemical reaction. - **Possible Explanations:** - **Chemical Reaction:** If new substances are formed that release gas (e.g., carbon dioxide), this indicates a chemical change. - **Physical Change:** Bubbling can also occur from physical processes like boiling, where the liquid changes to vapor without forming new substances. **Conclusion:** While bubbling can indicate a chemical reaction, it is not definitive proof on its own. To confirm a chemical reaction, additional observations such as a color change, temperature change, or formation of a precipitate should be considered. --- **Summary:** The rearrangement of atoms happens through chemical reactions involving the breaking and forming of bonds. In the given scenario, bubbling may suggest a chemical reaction, but further evidence is needed to confirm it conclusively.
