According to the Law of Conservation of Matter is this drawing accurate?
A. The drawing is correct because there are larger molecules on the reactant side.
B. The drawing is incorrect, because there are more molecules on the products side.
C. The drawing is correct, because there are eight white atoms and eight red atoms on each side of the reaction.
D. The drawing is incorrect, because there are different numbers of molecules on each side of the reaction.
The correct Answer and Explanation is:
The correct answer to this question is C. The drawing is correct, because there are eight white atoms and eight red atoms on each side of the reaction.
Explanation:
The Law of Conservation of Matter states that matter cannot be created or destroyed in a chemical reaction. This means that the total number of atoms of each element must remain the same on both the reactant and product sides of a chemical equation.
Let’s break down the options:
- A. The drawing is correct because there are larger molecules on the reactant side.
This is incorrect. The size of the molecules is not relevant to the Law of Conservation of Matter. What matters is the number and type of atoms on both sides of the reaction. - B. The drawing is incorrect, because there are more molecules on the products side.
This could be misleading. The law focuses on the number of atoms, not the number of molecules. As long as the number of atoms of each element is equal on both sides, the drawing can still follow the law even if the number of molecules differs. - C. The drawing is correct, because there are eight white atoms and eight red atoms on each side of the reaction.
This is correct. If there are the same number of white atoms (let’s assume they represent one element, like hydrogen) and red atoms (representing another element, like oxygen) on both sides of the reaction, the Law of Conservation of Matter is upheld. This indicates that matter is conserved, making the drawing accurate. - D. The drawing is incorrect, because there are different numbers of molecules on each side of the reaction.
This is incorrect. As mentioned earlier, the number of molecules is not as important as the number of atoms when considering the Law of Conservation of Matter. As long as the total number of atoms of each element is the same on both sides, the drawing can be correct.
Therefore, C is the most accurate choice because it correctly applies the Law of Conservation of Matter, focusing on the conservation of atoms.
