Chemical equations follow experiment. Experiment does not follow chemical equations.

Explanation:

So how do you know? You do the experiment, and interpret the result. You know that there is a mass balance. If there are 10 g of reactant, there can be at most 10 g of product. In practice, you are not even going to get 10 g. There is also a balance in electronic charge; there does not seem to be one on your equation.

So to your question; you mixed dihydrogen gas, sodium chloride, and sulfate dianion (i.e. #SO_4^(2-)#). This does not correspond to any chemical reaction I know. I think you have made a mistake transcribing the question.
