The Law of Conservation of Mass states that "In a physical process there is no change in composition of matter and the state of matter alone changes." Examples of these in daily life are the melting of ice and the boiling of water.

∙ 13y agoThe law of conservation of mass states that the mass of the reactants and the mass of this produces must be equal; mass can neither be created nor destroyed. By using coeffiects we can balance a chemcial equation to make the reactants equal to the products. For example, Fe + HCl -> FeCl2 + H2. This equation is unbalanced. There is 1 hydrogen in the reactants, and 2 in the product. There is 1 chlorine in the reactants and 2 for the produces. We must therefore balance the equation to follow the law of conservation on mass. Therefore our chemical equation should be presented as : Fe + 2HCl -> FeCl2 + H2.

If you weigh a cup with an ice cube in it in a closed bag, then when it melts it will still have the same mass (that means you weigh it again).

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 the law of conservation of matter using your own examples?
Total amount of mass energy in a closed system.
Which law physical science must be followed when balancing chemical equations?
the law of conservation of mass
In what situations would mass be conserved?
This is a general law of nature - the law of mass conservation.
What law states that the mass can not be lost or gained in a chemical reaction?
The law of conservation of mass states that in a chemical reaction the mass of the reactants must equal the mass of the product.
Examples of scientific law?
boyle's law, charles' law, law of conservation of mass.
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.
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 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.
How might the law of conservation of matter apply to daily life?
Law of conservation of mass shows that matter is conserved no matter what it undergoes. Some examples are ice cubes that melt to give same mass of liquid, oxidation of copper and closed metamorphic systems.
What are some alike things to the law of conservation of matter?
There is the law of conservation of mass, and the law of conservation of energy. All three state: (Mass/Matter/Energy) cannot be created or destroyed, simply transferred.
What types of changes observe the law of conservation of mass?
All changes, other than some nuclear reactions, must obey the Law of Conservation of Mass. Chemical reactions, physical changes, heating, cooling, and phase changes must obey the Law of Conservation of Mass.
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
How are the law of conservation of enegry and the law of mass similar?
The Law of conservation of Energy applies to mass as mass is a form of energy, E=mc2.
What is the law of conservation of matter using your own examples?
Total amount of mass energy in a closed system.
Which scientific law predicts that the mass of the reactants before a chemical reaction will equal the mass of the products after the reaction has taken place?
Law of Conservation of Mass (aka Law of Conservation of Matter)
Law of conservation?
A "law of conservation" is a law, in physics, that states that some quantity doesn't change over time. There are several conservation laws; such as the law of conservation of mass, of energy, of momentum, of rotational momentum, of electric charge, of color charge, and several others more.
