Question

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

Also balance the equations.

(B) Zn(s) +`H_2SO_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_2S` (g)  `→` CuS (S) + `H_2SO_4` (I)

(F) Zn (S) + `CuSO_4` (aq)  `→` `ZnSO_4` N  (aq) + Cu  (s) 

(H) NaOH + HCI  `→` NaCI + `H_2O` 

(I) KOH + `H_2SO_4`  `→` `K_2SO_4`  + `H_2O`

Solution

1. Combination reactions . 

(D) `NH_3` (g) + HCI (g)  `→` `NH_4` CI (S)

  Is there an error in this question or solution?
