which of the models of a chemical reaction best represents the law of conservation of mass?
which of the models of a chemical reaction best represents the law of conservation of mass?
Answer
Explanation:
Step1: Recall Law of Conservation of Mass
The law states that mass is neither created nor destroyed in a chemical reaction. So, the number of atoms of each element should be the same on both the reactant and product sides.
Step2: Analyze each model
Check each of the models A, B, C, D to see if the number of atoms of each type is equal before and after the reaction. The model with equal - atom counts on both sides best represents the law.
Answer:
(Without seeing the actual models, cannot determine the specific option. But the correct answer will be the model where the number of atoms of each element is the same on the reactant and product sides, e.g., if model C has equal atom - counts for all elements on both sides, the answer is C.)
