3 Mg + 1 Fe2O3 + 3 MgO + 2 Fe; What is the ratio of moles of Mgo to moles Fe?

a) 1 mol Fe/ 2 mol Fe

b) 3 mol Mgo / 2 mol Fe

c) 2 mol Mg/ 3 mol Fe

d) 3 mol Mg / 2 mol Fe

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.

The answer is letter c

The answer is d.potassium
