Are all reversible reactions at equilibrium? explain why or why not.

To identify a diatomic gas (X2), a researcher carried out the following experiment: She weighed an empty 2.2-L bulb, then filled it with the gas at 1.70 atm and 26.0 ∘C and weighed it again. The difference in mass was 4.3 g. Identify the gas.
