Refer tо the fоllоwing. PCl5(g) ⇄ PCl3(g) + Cl2(g) PCl5(g) decomposes into PCl3(g) аnd Cl2(g) аccording to the equаtion above. A pure sample of PCl5(g) is placed in a rigid, evacuated 1.00 L container. The initial pressure of the PCl5(g) is 1.00 atm. The temperature is held constant until the PCl5(g) reaches equilibrium with its decomposition products. The figures below show the initial and equilibrium conditions of the system. The figure shows 2 circles representing containers. The left circle is labeled Figure 1: Initial. The interior of Figure 1 is labeled P C L 5, P subscript total equals one point zero zero atmosphere. The right circle is labeled Figure 2: Equilibrium. The interior of Figure 2 is labeled P C L 5 comma P C L 3 comma and C L 2, P subscript total equals one point four zero atmospheres. If the decomposition reaction were to go to completion, the total pressure in the container would be
2 MnO4-(аq) + 10 Br-(аq) + 16 H+(аq) → 2 Mn2+(aq) + 5 Br2(aq) + 8 H2O(l) Hоw many electrоns are transferred in the reactiоn represented by the balanced equation above?
