<span>2<span>N2</span>+3<span>H2</span>→2N<span>H3
That's the balanced equation. As shown, 4 molecules of N2 would react with 12 molecules of H2. Since not that much H2 molecules exist, then it would serve as the limiting reactant. Therefore:
9 mol H2 * (2NH3 / 3H2) = 6 molecules of ammonia

yes substances Do react by mass
Answer:
Forensics.
Explanation:
That would be Forensics. Clues from a scene of a crime like clothing, blood and so on can be analysed in the science laboratory , helping to solve the crime.
Alchemy is not science, nor ethics nor politics.
Dissolved organic substance present in natural water is a complex mixture compounds and contains most of the reduced carbon present in aquatic ecosytem . this can not be easily treated or disinfected by the conventional treatment . the experiments show that water sample with higher dissolved substance need higher cholrine demand . this is the reason that before disinfecting with chlorine ..... need to remove organic substance {{{ because it increase chlorine demand }}}
