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.

Explanation:

fire could start, buildings collapsing, and ash falling from the sky.

explanation:

this is because the buildings or plants could catch on fire and the buildings would most likely collapse. lastly ash would fall because all the burning would cause ash to fall from the sky.

hope this .

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume
