Question

Which one of the following laws directly explains the law of conservation of mass?
A. Hund’s Rule
B. Dalton’s Law
C. Avogadro’s Law
D. Berzelius hypothesis

Answer 1

The law of conservation of mass expresses that mass in a detached system is neither made nor destroyed by chemical reactions or physical changes. As indicated by the law of conservation of mass, the mass of the products in a chemical reaction must rise to the mass of the reactants.

Complete answer:
Dalton's atomic theory was the first to portray all matter in quite a while of atoms and its properties. Dalton put together his theory with respect to the law of conservation of mass and the law of constant composition. He expressed that matter is made of small indivisible particles called atoms. Atoms of a given component are indistinguishable in mass and properties.
A compound is framed because of blends of at least two particles of various components. A substance reaction is a modification of atoms. Atoms of a given element are indistinguishable in mass and properties.
The law of conservation of mass says that matter is not created or destroyed in a closed system. That means if we have a chemical reaction, the amount of each element must be the same in the starting materials and the products. We use the law of conservation of mass every time we balance equations!

Note:
Since it expresses that atoms neither be created nor destroyed, Dalton's theory recommends that the net mass of the taking an interest species in a chemical reaction is moderated. This proposal, accordingly, represents the law of conservation of mass.
