What else can I help you with?
The law of conservation o mass states that the mass of all substance before physical change equals the mass of all substances after the change?
That statement is incorrect. The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. The total mass of the products of a reaction is always equal to the total mass of the reactants.
When wood is burned in a closed container its mass does not change is that observation or law?
In a closed container the mass of reactants (wood) and products (carbon dioxide, water, ash) remain unchanged; this is the low of mass conservation.
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.
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.
The statement matter can be neither created nor destroyed by chemical means but it can be changed from one form to another is the chemical law of?
The statement you provided is known as the Law of Conservation of Mass. This law states that in a chemical reaction, matter is neither created nor destroyed, but can only change form or be rearranged. It is a fundamental principle in chemistry.
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.
The Law of Conservation of Mass states that the equation for a chemical reaction will always be unbalanced?
That statement is incorrect. The Law of Conservation of Mass states that mass is conserved in a chemical reaction. This means that the total mass of the reactants must equal the total mass of the products, leading to a balanced chemical equation.
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.
The law of conservation o mass states that the mass of all substance before physical change equals the mass of all substances after the change?
That statement is incorrect. The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. The total mass of the products of a reaction is always equal to the total mass of the reactants.
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 does the law of conservation mass states that during a chemical reaction total mass is what?
The law of conservation of mass states that during a chemical reaction, the total mass of the reactants is equal to the total mass of the products formed. This means that mass is neither created nor destroyed in a chemical reaction, only rearranged.
Mass isn't lost when the reactants turn into products?
That's correct. According to the law of conservation of mass, matter cannot be created or destroyed in a chemical reaction. The total mass of the reactants will always be equal to the total mass of the products in a closed system.
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.
When wood is burned in a closed container its mass does not change is that observation or law?
In a closed container the mass of reactants (wood) and products (carbon dioxide, water, ash) remain unchanged; this is the low of mass conservation.
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.
Which atom is used as the standard for the atom mass scale?
This is an isotope of carbon (carbon-12); after the rules of IUPAC the correct expression is atomic weight not atomic mass.
