How does a balanced chemical equation demonstrate the Law of Conservation of Mass?(1 point)
Responses
it shows that all compounds remain bonded after the reaction
it shows that the properties of the elements stay the same after the reaction
it shows that only physical changes follow the Law of Conservation of Mass
it shows that no atoms have been gained or lost during the reaction
The correct answer is: it shows that no atoms have been gained or lost during the reaction.
The correct response is: "it shows that no atoms have been gained or lost during the reaction."
A balanced chemical equation demonstrates the Law of Conservation of Mass because it follows the principle that matter cannot be created or destroyed in a chemical reaction. In other words, the total mass of the reactants must be equal to the total mass of the products.
To balance a chemical equation, you need to ensure that the number of atoms of each element is the same on both sides of the equation. This means that no atoms are created or destroyed during the reaction, only rearranged to form different compounds.
For example, in the equation:
2H2 + O2 -> 2H2O
There are four hydrogen atoms on the left side (2H2) and four hydrogen atoms on the right side (2H2O). Similarly, there are two oxygen atoms on the left side (O2) and two oxygen atoms on the right side (2H2O). This balancing ensures that no atoms have been gained or lost during the reaction, illustrating the Law of Conservation of Mass.
