Question

In an experiment to" verify the law of conservation of mass" , four student A, B, C, D noted down the following observations of the difference in mass of the apparatus before and after the chemical reaction.
A - 4g, B - 8g , C- 0g ,D - 10g
which student performed the experiment correctly and why?

Answer 1

students perform the experiment correctly
this is because as we know that the mass of the reactant side is equal to the mass of the product side according to the conservation of mass
so the difference between the mass of the reaction sides and the mass of the products that will be zero
that is why students perform the experiment correctly
