It's a law of nature - the way our Universe works. Whether there is a purpose in the laws of nature... Well, that depends whether you believe whether the Universe was made by God, or by random chance. Perhaps the Universe is more organized that way. In any case, this law is closely related to some other laws, such as conservation of energy, and conservation of momentum.

What is conserved in physical changes?
Mass and energy
What is a balance equation that indicate that it is conserved?
The mass of reactants must be equal to the mass of products.
What happens to mass during a chemical change?
Mass is conserved. This means it remains constant.
Is mass conserved in the chemical reaction of zinc and iodine?
Of course !
In an ordinary chemical reaction the mass of the product you?
In an ordinary chemical reaction, the mass of the products is equal to the mass of the reactants. Matter is conserved.
Is mass conserved when neutralization takes place?
Mass is conserved. It is a law of nature.
Is mass conserved when nickel reacts chemically?
Yes. Basically, mass is always conserved.Yes. Basically, mass is always conserved.Yes. Basically, mass is always conserved.Yes. Basically, mass is always conserved.
Why is mass conserved during the combution of methane?
Its conserved during the combustion of anything - the mass of the products is always equal to the mass of the materials that react.
Which is not conserved mass acceleration energy momentum?
Acceleration is not conserved. Energy can not be created nor destroyed. Mass and momentum are both conserved through a set time.
What is conserved when one balances a chemical equation?
Mass (Matter) and Energy is conserved during a Chemical equation
In a nuclear reaction WHAT does not have to be conserved?
While overall ENERGY has to be conserved, MASS does not. In a nuclear reaction mass can be converted into energy so the mass of the products may be less than the mass of the reactants. The difference in mass is converted into energy as Einstein's equation describes (E=MC squared). In a chemical reaction MASS has to be conserved.
How is mass conserved in a cup of tea?
i don'know
What is always conserved in a chemical reaction?
mass
Is mass conserved in sugar and tea?
yes
What is conserved in physical changes?
Mass and energy
When did albert Einstein invent e equals mc2?
In the beginning of the 20th century. He proposed mass-energy equivalence in 1905, and set out to mathematically express this. E = mc2 shows that energy can be converted into mass, and mass into energy. Thus, we no longer say that mass is conserved, or energy is conserved. But rather, we say that mass-energy is conserved.
Is energy conserved in a nuclear reaction?
Yes. Basically, energy is ALWAYS conserved. The popular saying, that in a nuclear reaction mass is converted to energy, is plainly wrong, since both mass and energy are conserved. Read about "mass deficit", for example in the Wikipedia, for more details.
