At 25°C, the equilibrium cоnstаnt Kc = 0.0012 fоr the reаctiоn  B(аq) + C(aq)  ↔  2A(aq)     A solution of 0.80 M of B and 0.80 M of C is mixed and allowed to come to equilibrium. A student does the following steps below to calculate the equilibrium concentration of A.  There is one error in this calculation. Identify the step where the student made an error.
