How does a balanced chemical equation demonstrate the Law of Conservation of Mass?
1. It shows that only physical changes follow the Law of Conservation of Mass
2. It shows that the properties of the elements stay the same after the reaction
3. It shows that all compounds remain bonded after the reaction
4. It shows that no atoms have been gained or lost during the reaction
4. It shows that no atoms have been gained or lost during the reaction
4. It shows that no atoms have been gained or lost during the reaction
A balanced chemical equation ensures that the Law of Conservation of Mass is satisfied. According to this law, matter cannot be created or destroyed in a chemical reaction, only rearranged. A balanced equation means that the number of atoms on both sides of the equation is equal, indicating that no atoms have been gained or lost during the reaction.
The correct answer is option 4: It shows that no atoms have been gained or lost during the reaction.
A balanced chemical equation demonstrates the Law of Conservation of Mass, which states that mass is neither created nor destroyed in a chemical reaction. This law means that the total number of atoms of each element present in the reactants must be equal to the total number of atoms in the products.
In a balanced equation, the number of atoms of each element on the left side (reactants) must be equal to the number of atoms of that same element on the right side (products). This ensures that no atoms are gained or lost during the reaction, thereby obeying the Law of Conservation of Mass.
To balance a chemical equation, one needs to adjust the coefficients in front of the formulas of the reactants and products, making sure that the number of atoms of each element is the same on both sides of the equation. This balancing process ensures that mass is conserved throughout the reaction and that no atoms are created or destroyed.
Options 1, 2, and 3 are incorrect because they do not accurately describe how a balanced chemical equation demonstrates the Law of Conservation of Mass.
