Question

List 10 examples if formula metal+acid gives rise to salt+h2

Answer 1

examples are:-
1. Zn + H2SO4 gives ZnSO4 (aq) + H2(g)
2. Mg + H2SO4 → MgSO4 + H2
3.2NaOH + Zn ⇨ Na2ZnO2 + H2
4.2NaOH + 2Al + 2H2O ⇨ 2NaAlO2 + 2H2
5.HCl + NaOH ⇨ NaCl + H2O
6.2HCl + Ca(OH)2 ⇨ CaCl2 + 2H2O
7.H2SO4 + 2NaOH ⇨ Na2SO4 + 2H2O
8.HNO3 + NaOH ⇨ NaNO3 + H2O
