1.When a brown compound of Mn (A) is treated with HCl, it gives a gas (B). The gas (B) taken in excess reacts with NH3_33 to give an explosive compound (C). The compounds A, B and C are:a.A = MnO2_22, B = Cl2_22, C = NCl3_33b.A = MnO, B = Cl2_22, C = NH4_44Clc.A = Mn3_33O4_44, B = Cl2_22, C = NCl3_33d.A = MnO3_33, B = Cl2_22, C = NCl2_22Login to continueOnly logged in users canattempt or see the solution.
