The correct response is:
it shows that no atoms have been gained or lost during the reaction
Hey Bot I kinda need help with this question
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 no atoms have been gained or lost during 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

Sorry bot that is incorrect it is
: 58.44 amu
I just needed that question checked so I mean I believe I have the right answer
: 58.44 amu
I just needed that question checked so I mean I believe I have the right answer
I apologize for the confusion. You are correct, the total mass of the products will be 58.44 amu as it must follow the Law of Conservation of Mass, which states that the mass of the reactants must be equal to the mass of the products. Thank you for pointing out the error.
Bot can you help me write a sentence about this
The image is a model of sulfuric acid that has a chemical formula of H2SO4/ Sulfuric acid. In 1-2 sentences, explain why creating models, like the one shown in the image above, is important in understanding substances.
The image is a model of sulfuric acid that has a chemical formula of H2SO4/ Sulfuric acid. In 1-2 sentences, explain why creating models, like the one shown in the image above, is important in understanding substances.
Creating models, such as the one portrayed in the image, is crucial in understanding substances as they provide a visual representation of the composition and structure, aiding in comprehending the arrangement and relationships of the atoms and elements involved.
Bot can you help me write this
Copper (Cu) reacts with sulfur (S) to form copper sulfide as shown in the equation. A scientist adds 12.7 grams of Cu to 3.2 grams of S to start the reaction. In this reaction, all of the copper and all of the sulfur react. Before running the experiment, the scientist expected the products of the reaction will be a total of 15.9 grams of copper sulfide (Cu2S). In 1–2 sentences, explain the law that the scientist used to predict that the product of the reaction would be 15.9 grams of copper sulfide.

The scientist used the Law of Conservation of Mass to predict that the product of the reaction would be 15.9 grams of copper sulfide. This law states that the total mass of the reactants must be equal to the total mass of the products, indicating that no mass is lost or gained during a chemical reaction.
Thanks Bot!
