Question

making use only of substance choosen from those given below give equation for reaction by which could obtain hydrogen, Sulphur Dioxide, carbon dioxide, zinc carbonate substances are zinc,calcium carbonate, sulphuric acid, sodium carbonate, sodium sulphate, calcium carbonate, zinc sulphate ​

Answer 1

26.

Making use only of a substance chosen from those given below:

Dilute                                      sulphuric acid sodium carbonate

Zinc                                         sodium sulphite

Lead                                         calcium carbonate

Give the equation for the reaction by which you could obtain:

(i)  Hydrogen

(ii)  Carbon dioxide

(iii)  Zinc carbonate (two steps required)

i)  Zn +H2SO4 ---> ZnSO4 +H2

ii)   Na2CO3 +H2SO4 ----> Na2SO4 +H2O +CO2

iii) ZnSO4 +Na2CO3 ----> ZnCO3 +Na2SO4

Answer 2

i) Zn +H2SO4 ---> ZnSO4 +H2

ii) Na2CO3 +H2SO4 ----> Na2SO4­ +H2O +CO2

iii) ZnSO4 +Na2CO3 ----> ZnCO3 +Na2SO4

i only know this much.........(sorry)
