Question

As stated in the text convincing examples that demonstrate the law of conservation of matter outside of the laboratory are few and far between. Indicate whether the mass would increase decrease or stay the same following scenarios work chemical reactions take place

Answer 1

The law of conservation of energy remains the same for any kind of chemical or physical energy. Since that happens inside laboratory or outside it anywhere in the nature.

Step-by-step explanation:

Any example that will be considered will demonstrate no change in ultimate mass and any kind of energy that is involved in the reaction can only change the form of its nature while the total energy remains conserved.

There can be no gain or loss in mass or energy in any reaction that takes place reactant and product and energy should remain same.

For example rolling balls force with which it is thrown the distance reached by the ball would depend on the frictional energy and air resistance acting on it and on considering these forces it shall remain equal to the original source.
