Answer variants:
a. \(2H_2S\)(g) + \(3O_2\)(g) → \(2H_2O\)(l) + \(2SO_2\)(g)
b. \(BaCl\)(aq) + \(ZnSO\)(aq) → \(BaSO_4\)(s) + \(ZnCl_2\)(aq)
b. \(BaCl\)(aq) + \(ZnSO\)(aq) → \(BaSO_4\)(s) + \(ZnCl_2\)(aq)
Al is the reducing agent. Al is more reactive than Mn.
\(CO\)(g) + \(2N_2\)(g) \(\xrightarrow[]{340 atm}\) \(CH_3NH\)(l)
The reaction will take place in presence of darkness. This reaction is used in colour photography.
