What are the entries in the Change row?

Answer:

A_(g) + BC_(g) ---> AB_(g) + C_(g)

Experiment #2	[A]	[BC]	[BC]	[C]
Initial	0	0	4.0	4.0
Change	+3.2	+3.2	-3.2	-3.2
Equilibrium	3.2	3.2	0.8	0.8

In this Experiment there is no A_(g) or BC_(g). But the final amount is the same as observed in Experiment #2.

Notice the change corresponds to the stoichiometric coefficients in the balanced chemical equation
