1. consider the reaction
2 kmno4 + 10 ks. oz + 16 hcl → 2 mncl2 + 5 k2s40671
03 + 16 hcl → 2 mncl2 + 5 ks406 + 12 kcl + 8 h2o
a) what is the oxidation number of
8 pts
i. mn in mncl2
ii. mn in mn04
iii. s in k2s406
iv. cl in hcl

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 would be
