5.Nitrogen and hydrogen are mixed, to make ammonia. For a time, the rate of the forward reaction is greater than the rate of the back
reaction. Has equilibrium been reached?

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.

Exothermic,  physical change after it is already baked

Olá. porque a reação na temperatura é muito rapida a do copo : )
