Question

Classify the following reactions as combination . Also balance the equations.

Also balance the equations.
(a) \[\ce{CaCO3(s)->[heat]CaO(s)+CO2(g)}\]
(b) Zn(s) +`"H"_2"SO"_4`  `→`  `"ZnSO"_4` (S) + `"H"_2` (g) 

(c) `"AgNO"_3` (aq)  + NaCI (aq) `→` Ag CI (S) + `"NaNO"_3` 

(d) `"NH"_3` (g) + HCI (g)  `→` `"NH"_4` CI (S)

(e) `"CuSO"_4` (aq)  + `"H"_2"S"` (g)  `→` CuS (S) + `"H"_2"SO"_4` (I)

(f) Zn (S) + `"CuSO"_4` (aq)  `→` `"ZnSO"_4` N  (aq) + Cu  (s) 

(g)\[\ce{Ca(s)O2(g)->[heat]CaO(s)}\]

(H) NaOH + HCI  `→` NaCI + `"H"_2"O"` 

(I) KOH + `"H"_2"SO"_4`  `→` `"K"_2"SO"_4`  + `"H"_2"O"`

Answer 1

1. Combination reactions . 

(d) `"NH"_3` (g) + HCI (g)  `→` `"NH"_4` CI (S)

(g) \[\ce{Ca(s)O2(g)->[heat]CaO(s)}\]
