. Se colocan 5g de hierro (Fe) con 7g de azufre (S) para formar pirita (FeS2). Indique cuál es el reactivo en exceso y que masa de éste no reacciona. a) Fe; 2,48 b) Fe; 1,24 c) S; 1,29

d) S; 2,61 e) Fe; 3,25

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.

It idk haha what are we doing?

Electrons are emitted
