How does the law of conservation of mass relate to the balancing of equations?
Matter cannot be created or destroyed in chemical reactions. This is the law of conservation of mass. In every chemical reaction, the same mass of matter must end up in the products as started in the reactants. Balanced chemical equations show that mass is conserved in chemical reactions.
Which statement best describes the law of conservation of mass?
In a chemical process, the mass of all the products will be the same as the mass of all the reactants.
Why is the law of conservation of mass demonstrated when balancing an equation?
Balancing equations demonstrates the fundamental law of the conservation of mass. It shows that you cannot create or destroy mass in a chemical reaction, so the mass stays constant.
How is the law of conservation of mass related to balancing equations quizlet?
Law of conservation of masses implies that the mass of products formed after a chemical reaction should always be equal to the mass of reactants at the beginning of the reaction. This is theoretically achieved by balancing chemical equations.
Which of the following is the best statement of the law of conservation of mass quizlet?
The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations.
Which statement best describes the law of conservation of matter with regard to chemical reactions?
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.
Which statement is balanced and represents conservation of matter?
The law of conservation of matter says mass is neither created nor destroyed so the mass of the reactants is equal to the mass of the products. What amount and substance balance this reaction?
Which statement about the law of the conservation of mass is true?
The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction.
Which statement best describes the law of conservation of mass quizlet?
The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations.
Which statement best represents the law of conservation of matter with regard to chemical reactions quizlet?
The Law of Conservation of Mass states that in a chemical reaction the total mass of reactants is equal to the total mass of products.
Which of the following is the best statement of the law of conservation of energy quizlet?
Step 1. The correct answer is A. The law of conservation of energy states that the total energy in a system or object remains constant or conserved over time. In this case, energy can never be created nor destroyed during chemical reactions and physical transformations.
Which feature of a chemical equation represents the law of conservation of matter balanced equation chemical formulas coefficients subscripts?
Answer and Explanation: Coefficents (choice a) represent the law of the conservation of matter in a chemical reaction. The coefficients are used to mass balance the…
Which best describes the law of conservation of mass quizlet?
The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations.
Which statement best represents the law of conservation of matter with regard to chemical reactions?
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.
Which statement best describes the law of conservation of energy?
The correct answer is A. The law of conservation of energy states that the total energy in a system or object remains constant or conserved over time. In this case, energy can never be created nor destroyed during chemical reactions and physical transformations.
Which statement describes the law of conservation of mass quizlet?
Which statement describes the Law of Conservation of Mass? Mass in an isolated system is neither created nor destroyed by chemical reactions.
Which equation obeys the law of conservation of mass?
balanced equation A balanced equation obeys the Law of Conservation of Mass. This is an important guiding principal in science. Finally, a balanced equation lets up predict the amount of reactants needed and the amount of products formed.
Which of the following statement correctly describes the law of conservation of energy quizlet?
Which statement describes the law of conservation of energy? Energy cannot be created nor destroyed, but it changes from one form to another.
Which of the following summarizes the law of conservation of mass when dealing with a chemical change?
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.
What is the meaning of law of conservation of mass?
The law of conservation of mass states that. “The mass in an isolated system can neither be created nor be destroyed but can be transformed from one form to another”. According to the law of conservation of mass, the mass of the reactants must be equal to the mass of the products for a low energy thermodynamic process.
Which of the following statements correctly describes a law of conservation of energy?
Answer and Explanation: The law of conservation of energy states that energy can neither be created nor destroyed, but only converted between various forms.
What is the law of conservation of mass describe with an activity?
The law of conservation of mass states that matter cannot be created nor destroyed, only it's form changed. Take the example of burning a piece of paper. It seems that the mass shrinks as the paper burns.
Which of the following equation is based on conservation of mass?
Explanation: The equation based on the principle of conservation of mass is called the continuity equation.
Which is the best example of law of conservation of mass?
The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted.
Which of the following statements correctly describes the law of conservation of matter?
Answers. 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.
Which of the following illustrates the law of conservation of mass?
The correct answer is b) 1.70g of reacts with 100ml of 0.1 M HCL to produce 1.435g of AgCl and 0.63g of . Explanation: The law of conservation of mass states that the sum of reactants is equal to the sum of products. It can be also states as " mass can neither be created nor be destroyed"
Does a balanced chemical equation obey the law of conservation of mass?
(c) A balanced equation obeys the law of conservation of mass and so does an unbalanced equation.
What is law of conservation of mass describe with an activity?
The law of conservation of mass states that matter cannot be created nor destroyed, only it's form changed. Take the example of burning a piece of paper. It seems that the mass shrinks as the paper burns.
Which of the following statement is true about the law of conservation of mass?
Assertion :In a chemical reaction, the sum of the masses of the reactants and products remains unchanged. Reason: According to the law of conservation of mass, matter can neither be created nor be destroyed.
What does the mass of the reactants and products tell us about the law of conservation of mass Why?
The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant.
