Can sulfuric acid be decomposed by chemical change?

Answer 1

The sulfur in sulfate is fully oxidized..........

The sulfur in sulfate is fully oxidized..........i.e. #stackrel(+VI)S#. I daresay, you could find a reaction in which sulfur is reduced.

Indeed, sulfate-reducing bacteria exist; these ingenious little critters convert sulfate to sulfide.

#SO_4^(2-) +8H^(+) + 8e^(-) rarr S^(2-)+4H_2O(l)#

The idea that this reaction might have been carried out by the first microorganisms, some 300–400 million years ago, is extremely alarming.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
