Question

write the names of the gases which are released when the following salts are reacted with H2SO4 ? also write the chemical equations 1) CaCo3 2) Fes 3) BaCl2 4) Pb ( NO3) 2 5) ZnSO3​

Answer 1

Answer:

Correct option is

D

(b) & (d)

BaCl

2

(aq)+Na

2

SO

4

(aq)→BaSO

4

(s)+2NaCl(aq)

The types of reactions are (b) Precipitation and (d) Double displacement.

A precipitate of bariumsulphate is obtained.

In double displacement reaction, two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.

So, the correct option is D.
