Step-by-step explanation:
The metal reacts differently with dilute acid and concentrated acid. That is the character of metal. With dilute sulphuric acid, zinc gives hydrogen.
Zn + H2SO4 (dil.) → ZnSO4 + H2
The same metals will react differently with concentrated sulphuric acid to give sulphur dioxide gas.
