Answer:
that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.
Explanation:
According to the law of conservation of mass, mass can only be conserved in an isolated system.
Recall:
The law of conservation of mass states that mass can neither be created nor destroyed. However, it can be converted from one form to another.
In an open system, the mass may not be conserved because materials and energy are being exchanged between the system and the surrounding.
The mass may also not be conserved in a closed system because energy can be exchanged between the system and the surroundings even though materials cannot.
An isolated system does not exchange materials or energy with its surrounding. Thus, mass is only conserved when a system is in an isolated state.
