Is the volume always equal as the reactants and products?
This is a very general statement, and the answer is no. However, the mass of the reactants must be equal to the mass of the products, under the law of conservation of mass.
What law represents a balanced chemical equation?
The law of conservation of mass, which states that in a closed system, mass is neither created nor destroyed, it can only change form. This means that in a chemical reaction that takes place in a closed system, the mass of the reactants equals the mass of the products.
What is meant by conservation of mass and energy?
Law of mass conservation in chemistry: in a chemical reaction the mass of reactants is equal to the mass of products.Law of energy conservation: in a closed system the energy remain constant.
Why Dalton's law of conservation of mass is incorrect?
It is incorrect by itself because energy can alter the mass web the mass is moving at high velocities. A more correct law is the law of conservation of mass-energy. For example... When a object is moving at the speed of light the electrons can be sped up therefor increasing its mas. This has been tested several times including at Havard.
In what situations would mass be conserved?
This is a general law of nature - the law of mass conservation.
What statement stays the mass of the reactants must equal the products?
This is the well-known law of mass conservation.
What scientific law is satisfied when balancing equations?
Law of Conservation of mass(atomic mass). As mass can be considered relative to energy, therefore Law of Conservation is also correct but Law of conservation of mass is is much more accurate because here mass is a much more accurate term that is required here. Here, since, we are balancing molecules, then we require atomic or molecular mass.
What does the law of conservation mass states that during a chemical reaction total mass is what?
D. always equal to the total mass of the products.
Is the volume always equal as the reactants and products?
This is a very general statement, and the answer is no. However, the mass of the reactants must be equal to the mass of the products, under the law of conservation of mass.
How are chemicals related to atomic mass?
The molar mass of a compound is the sum of atomic weights of the contained elements in the molecule.The expression atomic weight is correct for elements; for isotopes is correct atomic mass.
Why is there a need to balance equations?
Because the mass of the reactants must equal the mass of the products due to the Law of Conservation of Mass. By balancing the equation you show the correct proportions of chemicals.
What is isotopic weight in chemistry?
The correct expression is "atomic mass of the isotope"; it is related to 1/12 of the mass of the isotope carbon-12.
What law represents a balanced chemical equation?
The law of conservation of mass, which states that in a closed system, mass is neither created nor destroyed, it can only change form. This means that in a chemical reaction that takes place in a closed system, the mass of the reactants equals the mass of the products.
What law states that mass cannot be created or destroyed in chemical or physical changes?
The law of conservation of mass/matter states that mass/matter cannot be created or destroyed in chemical or physical changes.
How would you use the word conservation of mass in a sentence?
The Law of Conservation of Mass means that chemical reaction equations must be balanced, otherwise you have lost or gained matter out of nowhere.
What are the law of conservation of mass as it relates to phase changes?
it is the same as the law of conservation of mass
What is meant by conservation of mass and energy?
Law of mass conservation in chemistry: in a chemical reaction the mass of reactants is equal to the mass of products.Law of energy conservation: in a closed system the energy remain constant.
