Each atom of a particular element has a constant (average) weight, and in chemical reactions, the numbers and types of atoms in the reactants must be the same as the numbers and types of atoms in the products. This explains the law of the conservation of mass. Each molecule of a compound or polyatomic element is composed of a fixed number of one or more particular kinds of atoms; this explains the law of constant composition.

How does the atomic theory of matter explain the law of conservation of mass and law of constant composition?
Each atom of a particular element has a constant (average) weight, and in chemical reactions, the numbers and types of atoms in the reactants must be the same as the numbers and types of atoms in the products. This explains the law of the conservation of mass. Each molecule of a compound or polyatomic element is composed of a fixed number of one or more particular kinds of atoms; this explains the law of constant composition.
What is the term for a symbolic method of expressing the composition of an atomic nucleus?
atomic number
Each element has its own characteristic atom in which a. the atomic weight is constant b. the atomic number is constant c. the mass number is constant?
b. the atomic number is constant. The mass number is not constant because there are isotopes of an element that have the same number of protons but different number of neutrons. Likewise, there are isotopes of the same element with different atomic weights.
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 is the atomic number for stone?
Stone is a composition of various elements and thus does not have an atomic number. Its constituents, however, do.

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...
Is butter a mixture or a compound?
Butter is a mixture: Its atomic composition is not always constant from one source to another.
Which would mean that the energy in an isolated system would remain constant law of conservation of matter 1st law of thermodynamics second law of thermodynamics or the atomic theory of matter?
The first law of thermodynamics states that the energy of an isolated system is constant.
How does Dalton atomic theory explain the law of conservation of mass?
Dalton doesn't explain the law of conservation of mass.
When did Dalton publish law of constant composition?
Joseph Proust, based on experiments conducted at the end of the 18th Century claimed that elements combined in constant proportions. Dalton's atomic theory, (1903) built on this earlier work and put it into a theoretic framework.

Is atomic number constant?
It is constant for elements. IT depends on number of protons that atom has.
Do balanced equations account for the conservation of mass?
Yes. If an equation is balanced, it has the same number of each of the same types of atoms on each side. Since atomic mass is constant for each type of atom (when averaged over the various isotopes of each type that may be present, this demonstrates the conservation of mass.
What is a composition of a compound shown by?
The chemical formula of the compound. This shows the composition directly in atomic ratios, which can be converted to mass ratios by using the atomic weights of each element in the compound.
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.
