No it can't. In order to prove it absolutely true, you would have to set up and
observe every possible reaction, and document that mass is conserved in every
one of them. Which is impossible, because there are an infinite number of possible
reactions. But it's accepted as a law because so far, no exception to it has ever been
observed.
Well, technically, before somebody else jumps on this answer and shows why it
aint true . . .
That "law" is now amended to become the Law of Conservation of Mass and
Energy, since it was shown about 100 years ago that mass and energy are
equivalent and can convert in both directions. But the total doesn't change.
Scientists have already found that the law of conservation of mass is not absolutely true in all cases. Albert Einstein's famous equation, e = mc2 describes the amount of energy that can be created by transforming mass into energy, a process which happens in nuclear reactors or nuclear bombs, as well as in the sun (which could be considered a natural nuclear reactor). Aside from that, there are other situations in which even the broader rule of conservation of mass-energy does not apply. Virtual particals appear and disappear in violation of conservaton of mass-energy. So there are various exceptions. But in certain well defined circumstances, conservation of mass has been observed to be quite reliable.
The law of conservation of mass/matter states that mass/matter cannot be created or destroyed in chemical or physical changes.
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.
it is the same as the law of conservation of mass
The metal will rust over time but the mass of the container as a whole. The law of conservation of mass is not violated.

Yes absolutely
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.
The law of conservation of mass/matter states that mass/matter cannot be created or destroyed in chemical or physical changes.

it is the same as the law of conservation of mass
Law of mass conservation in chemistry: in a chemical reaction the mass of reactants is equal to the mass of products.Law of energy conservation: in a closed system the energy remain constant.
Law of Conservation of Mass (aka Law of Conservation of Matter)
absolutely, it will mostly effect how quickly it will accelerate relative to its mass, and how quicky it will fall (descend hills) and how slowly it will stop, more mass = slower deceleration. Also a bigger mass will maintain the conservation of momentum more easily.
The Law of Conservation of Mass is the concept that mass cannot be created or destroyed, it simply changes form.
The law of Conservation of Mass states that in ordinary chemical reactions, mass can not be created or destroyed.
The principle of conservation of mass states that in a chemical reaction, the total mass of the reactants must equal the total mass of the products.
