Why do you need a balanced equation to do stoichiometry?
A chemical equation must respect the law of mass conservation.
What are the basic assumptions in stoichiometry?
reactants completely change into products.no side reaction occurs.law of conservation of mass and law of definite proportions are obeyed.
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 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.
Why do you need a balanced equation to do stoichiometry?
A chemical equation must respect the law of mass conservation.
What law is based on the experiments of Lavoiser?
This is the law of mass conservation.
What are the basic assumptions in stoichiometry?
reactants completely change into products.no side reaction occurs.law of conservation of mass and law of definite proportions are obeyed.
How is the law of conservation of matter best represented in a chemical reaction?
The Law of Conservation of Mass states that mass cannot be created or destroyed. In a chemical reaction that means that the number of a certain element on one side must equal the same amount on the other.
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 is the name of the chemical law of which problems 2 and 3 ar based?
Law of the conservation of mass
What are chemical equations based on?
They are based on the chemical composition of reactants and products; 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 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 does the law of conservation of mass not apply to a chemical reaction?
Couldn't tell you how, because this is a false presumption:The law of mass conservation does FULLY apply to a chemical reaction.Antoine Lavoisier (Pioneer of stoichiometry) already showed that, although matter can change its state in a chemical reaction, the total mass of matter is the same at the end as at the beginning of every chemical change.
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.
