When hydrochloric acid reacts with sodium sulfide, hydrogen sulfide gas and sodium chloride are produced. how many moles of h2s will be generated by 2.56 moles of hcl?

The balanced equation that shows the stoichiometric reaction between sodium sulfide and hydrochloric acid to produce hydrogen sulfide gas and sodium chloride is Na2S+ 2HCl = 2 NaCl + H2S. Thus for every two moles of HCl, 1 mole of H2s gas is generated. In this case, when 2.56 moles of HCl is used,  1.28 moles of H2S is produced.

North atlantic current or north atlantic drift is the answer
