Mass stays the same because no matter is created or destroyed.
Explanation:
Regardless of what chemical reaction we have, in each case the law of mass conservation applies. The law of mass conservation states that the total mass of a reaction mixture is kept constant, as mass cannot be created or destroyed.
In this specific reaction, the total mass of the reactants should be equal to the total mass of the products when the reaction is complete.
In other words, if we add the mass of hydrogen to the mass of nitrogen, when the reaction is compete, assuming no reagent in excess, this should be equal to the mass of ammonia formed.
From the relative atomic mass of each element, it is possible to determine each element's molar mass by multiplying the molar mass constant (1 g/mol) by the atomic weight of that particular element. The molar mass value can be used as a conversion factor to facilitate mass-to-mole and mole-to-mass conversions.
answer: A homogeneous mixture has the same uniform appearance and composition throughout. Many homogeneous mixtures are commonly referred to as solutions. A heterogeneous mixture consists of visibly different substances or phases.
