Which best describes the law of conservation of mass?
The law of conservation of mass is best described by - The mass of the reactants and products is equal and is not dependent on the physical state of the substances.
The law of conservation of mass states that in a chemical reaction mass is neither created nor destroyed. For example, the carbon atom in coal becomes carbon dioxide when it is burned. The carbon atom changes from a solid structure to a gas but its mass does not change.
Therefore, the statement that best describes the way in which mass is conserved during chemical reactions is answer choice (D): the total mass of reactants is equal to the total mass of products.
Answer b: The law of conservation of matter says that in chemical reactions, the total mass of the products must equal the total mass of the reactants.
Question 29 Which statement best describes the Law of Conservation of Mass? The masses of the reactants in a chemical reaction are always equal.
Which best describes the law of conservation of mass? The mass of the reactants and products is equal and is not dependent on the physical state of the substances.
The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it's added from the outside.
The law of conservation of mass states that matter can neither be created nor be destroyed in a chemical reaction, i.e. mass before and after the chemical reaction is same.
Correct Response: C.
The law of conservation of mass states that matter is neither created nor destroyed during a chemical reaction.
The law of conservation of mass was given by Lavoisier. It states that mass can neither be created nor destroyed in a chemical reaction i.e. Total masses of reactants is equal to the sum of masses of products and the masses of unreacted reactants.
Which best represents the law of conservation of mass a skeleton equation or a balanced chemical equation?
Law of conservation of masses is accurately represented by a balanced chemical equation and not a skeleton equation. A balanced chemical equation accurately shows the validity of the law of conservation of masses as shown in part b of this question.
