How do acids and bases react with metals 5 examples?

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

Metal + acid – metal salt + H2

2Na + H2Co3 – Na2Co3 + H2

When a base combine with metal it forms metal salt / base and release hydrogen gas

 

Base + metal – base/metals/salt + H2

 

2NaoH + Zn – Na2ZnO3 + H2 (sodium Zincates)

Base reacts only with zinc and aluminum

Acids and Bases reacts with metals to produce salt and hydrogen gas is released.
Examples of Acid reacts with metals:
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.

Dimensions of the bar are 8.0 cm (width), 0.40 cm (height), and 310 


volume of the bar = width x height

                              = 8 x 0.4 x  310

                              = 992 cm³


if kind of iron costs $0.015 per cm³, the cost = 992 x 0.015

                              = $14.88
