the gas formed is hydrogen because on reacting with an acid like sulphuric acid ,metal displaces hydrogen in the acid solution and metal salt and hydrogen gas is formed
for example - Zn+H2SO4=ZnSO4+H2
i.e.,metal +acid=metal salt+hydrogen
for example - Zn+H2SO4=ZnSO4+H2
i.e.,metal +acid=metal salt+hydrogen
