Answer 1

The correct equilibrium equation for the reaction of zinc with dihydrogen sulfate is: Zn + H2SO4 → ZnSO4 + H2 None of the options presented show the correct equilibrium equation. However, option B is closest to the correct equation, but is unbalanced because the number of hydrogen and sulfur atoms on both sides of the equation is not equal. The correct equilibrium equation shows that zinc (Zn) replaces hydrogen (H) in dihydrogen sulfate (H2SO4), forming zinc sulfate (ZnSO4) and hydrogen gas (H2).
