For a reaction delta h= -286 kj. when is the reaction spontaneous a: when t delta s = 2(-286 kj) b: when t delta s= -286 kj c: when t delta s < -286 kj d: when t delta s > 0

explanation:

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
