Can anyone tell me 5 reactions of metals with acids?​

When an acid combines with metal it forms salt and release hydrogen gas

Explanation: 1.HCL + Zn=ZnCl +H2.

2.HCL + Ca = CaCl2 +H2.

3.H2SO4 + Zn = ZnSO4 + H2.

4.HNO3 + Ca = CaNO3+H2.

5.HCL + Mg= MgCl +H2.

1. Generally metals reacts with acids to form salt and releases hydrogen gas.

Metal + Acid → Salt + Hydrogen Gas

2. Magnesium reacts with acids to form salt and releases hydrogen gas which is tested by burning.

E.g. Mg (s) + 2HCl (l) → MgCl2 (s) + H2 (g)

Mg (s) + H2SO4 (l) → MgSO4 (s) + H2 (g)

2Al (s) + 6 HCl (l) → 2AlCl3 (s) + 6H2 (g)

Zn (s) + 2HCl (l) → ZnCl2 (s) + H2 (g)

Zn (s) + H2SO4 (l) → ZnSO4 (s) + H2 (g)

Fe (s) + 2HCl (l) → FeCl2 (s) + H2 (g)

Some metals reacts with dilute Nitric acid (HNO3) and produces salt and any of the nitrogen oxides (N2O, NO, NO2) and water. It is because HNO3 is a strong oxidising agent. It oxidises the H2 produced to water and itself gets reduced to any of the nitrogen oxides (N2O, NO, NO2).

Cu + 4HNO3 → Cu(NO3)2 + 2NO2 + 2H2O

However magnesium and manganese react with very dilute HNO3 to evolve H2 gas.

Mg + 2HNO3 → Mg(NO3)2 + H2

Such reaction is the most exothermic.

The reactivity of metals towards the acids decreases in the order Mg > Al > Zn > Fe. In the case of copper, no bubbles were seen and the temperature also remained unchanged. This shows that copper does not react with dilute HCl.
