What else can I help you with?
What word would you use to describe HgO in the reaction that Lavoisier is used to show conservation of mass?
The word to describe HgO in Lavoisier's reaction demonstrating the conservation of mass is "reactant." In this reaction, mercury(II) oxide (HgO) decomposes upon heating into mercury (Hg) and oxygen gas (O2). Lavoisier's experiment illustrated that the total mass of the reactants (HgO) equals the total mass of the products (Hg and O2), thereby confirming the principle of conservation of mass.
If The flask and its contents had a mass of 120 grams before the experiment and a mass of 120 grams after the experiment Which conclusion can best be made from these measurements?
That the Law of Conservation of Matter has been proven to be true once again. I could also conclude that the experiment occured within a closed sytem where no gas was lost. So many conclusions, so little time.
What is the mass number of the atom Mercury?
Mercury is a metal element. Mass number of it is 200.
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 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 does the Lavoisier's experiment show the law of conservation of mass?
No

Why would an experiment not demonstrate the law of conservation of mass?
An experiment may not demonstrate the law of conservation of mass if there are sources of error, such as incomplete data collection or unaccounted-for mass changes (e.g., evaporation, chemical reactions) during the experiment. Additionally, equipment malfunctions or improper experimental design could also lead to inaccurate results that do not align with the law of conservation of mass.
When heated mercury oxide produces oxygen plus mercury. What would be the combined mass of oxeyn and mercury if 20 g of mercury oxide were heated?
When 20 g of mercury oxide is heated, it will decompose into oxygen and mercury. The combined mass of oxygen and mercury will still be 20 g, as no mass is lost or gained in a chemical reaction according to the Law of Conservation of Mass.
What is law of consevation of mass with experiment?
The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction; it is simply rearranged. An experiment to demonstrate this is burning a piece of paper: the mass of the paper before burning will be the same as the mass of the ashes, smoke, and gases produced after burning. This experiment confirms that the total mass before and after the reaction remains constant.
What law is based on the experiment of Lavoisier?
The law of conservation of mass, also known as the law of conservation of mass-energy, is based on the experiments of Antoine Lavoisier. This law states that mass or matter cannot be created or destroyed in a chemical reaction, only changed from one form to another.

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 mercuarys mass?
1026.302 this is the mass of mercury 1026.302 this is the mass of mercury
How are the laws of conservation of mass and conservation of energy similar and how are they different?
The laws of conservation of mass and conservation of energy are similar in that both state that the total amount of mass or energy in a closed system remains constant over time. However, the conservation of mass applies specifically to mass, while the conservation of energy applies to energy in its various forms (kinetic, potential, etc.).
What is mercury's mass in kilogram's?
Mercury's mass is 0.33x1024kg.
What was lavoisiers greatest contribution to science?
His atomic theory. He was the one who thought that there were atoms in everything.
