It seems that you're referring to a specific diagram and images representing a chemical reaction, but I'm unable to see the images or the diagram you're mentioning.
To determine which image would best illustrate the conservation of matter in a chemical reaction, you should consider the following:
-
Reactants and Products: The images should clearly show that the number of atoms of each element is the same on both sides of the equation, which is a key principle of the conservation of mass.
-
Chemical Symbols and Formulas: Look for images that correctly depict the formulas of the reactants and products involved in the reaction.
-
Balanced Equation: Ensure the images display a balanced chemical equation, where the total number of atoms for each element is equal on both the reactant and product sides.
If you can describe the options or provide more details about the images (reactants shown, types of reactions, etc.), I could help guide you on which might best represent the conservation of matter.
