You are given a piece of paper and a match. The paper has a mass of 2.5 g. You then light the match and light the piece of paper on fire. After it burns, the remaining bits of paper weigh 0.5 g. Does this demonstration violate the conservation of mass? Explain why or why not?

The answer to the question on whether the burning violates the law of conservation of mass, we say that;

No, the demonstration does not violate the conservation of mass because the mass formed still adds up to the original mass.

The law of conservation of mass states that mass in an isolated system, matter can neither be created nor destroyed by chemical reactions or physical transformations. However, it could involve change in mass from one form to another.  

Now, we are told that the remaining bits of paper has a mass of 0.5 g while the original paper has a mass 2.5 g. The reason why the mass left is 0.5 kg is because the ashes and smoke from the burning will add up to give the original weight of the paper.

Thus, since when the ashes, and smoke add up to still give the original mass of 3.5 g, it means that the mass is neither created nor destroyed

its going to be mutualism cuz they both benefit from the relationship.
