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?
The law of conservation of mass, also known as the principle of mass conservation or Lavoisier's principle, states that matter is neither created nor destroyed in a chemical reaction. This means that the total mass of the reactants must equal the total mass of the products in a closed system.
What law states that the total mass of the reactants always equals the total mass of the products?
The law of conservation of mass. We now know that technically it's not quite true, but it's so close that the difference cannot be detected on the most sensitive balances we have.
Why law of conservation of mass should better be called as law of conservation of mass and energy?
Because energy can be converted into mass and vice versa. Thus, while the mass of a system is not conserved in a particular process, the mass and energy of a closed system is always conserved.
What law of conservation says atoms are neither lost nor gained during a chemical reaction?
The law of conservation of mass states that in a chemical reaction, mass is neither created nor destroyed - it is conserved. This means that the total mass of reactants must equal the total mass of products in a chemical reaction.
What is balancing a chemical equation so that the same number of atoms of each element is found in both the reactants and the products is an example of what?
Balancing a chemical equation is an example of the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction, only rearranged. Balancing ensures that the total number of each type of atom is the same on both sides of the equation.
Explain how the law of conservation of mass is supported when a log burns in a fire?
when the ashes are left
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 was John Dalton contributes in atomic theory?
It explained law of conservation of mass and law of constant proportion and laid foundation to atomic physics n chemistry...
What law states that mass cannot be created or destroyed in chemical or physical changes?
The law that states mass cannot be created or destroyed in chemical or physical changes is the Law of Conservation of Mass, also known as the Principle of Mass Conservation. This law implies that in a closed system, the total mass remains constant before and after any chemical or physical process, even if the substances undergo a change in form or state.
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.
Is the mass of wood and oxygen that allow it to burn equal the mass of ashes and the gas given off during the burning?
Yes. According to the law of conservation of mass, the mass of all the reactants must be equal to the mass of all of the products.
How this law was created law of conservation of mass?
it conserves mass
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.
After a fire the ashes have less mass and take up less space than the trees and vegetation before the fireHow can this be explained in terms of the law of conservation of mass?
No, it is not an exception . The supposed loss of weight is accounted for by the gases escaping from the reaction . If we weight the gases and the ashes , it will be the same as the log of wood There are no exceptions to the law of conservation of mass
What law states that the mass can not be lost or gained in a chemical reaction?
The law that states that mass can neither be created nor destroyed in a chemical reaction is the Law of Conservation of Mass, also known as the Law of Mass Conservation. This principle was first formulated by Antoine Lavoisier in the late 18th century and is a fundamental concept in chemistry.
What dose law of conservation of mass?
The Law of Conservation of Mass is the concept that mass cannot be created or destroyed, it simply changes form.
What was Antoine's law?
law of conservation of mass.
