Which chemical reaction is flawed? (answer ) a. 2ni3 > n2 + 3i2 b. 2h2 + o2 > 2h2o c. caco3 + 2hcl > cacl2 + h2o d. 2albr3 + 3cl2 > 2alcl3 + 3br2

Either you wrote down answer A wrong but C seems to be the flawed one. I may be mistake however, since A could be written done wrong

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.
