Gases A₂ and B₂ react according to the equation: A₂ + B₂ → A_xB_y . If equimolar ( not necessarily stoichiometrically equivalent) quantities are placed in a reaction vessel with a massless, frictionless piston and allowed to react to completion. The density of the gas mixture after reaction is 1.5X the original density. Find the empirical formula? Is there only one possibility? Explain.

The equation of an ellipse is x2/a2+y2/b2=1, where a and b are positive constants, a ³ b. The foci of this ellipse are located at (c, 0), and (-c, 0), where c = (a2 – b2)1/2. The eccentricity, e, of this ellipse is given by e=c/a, while the length of the ellipse’s perimeter is \int_0^((\pi )/(2)) 4a(1-e^(2)sin^(2)\theta )^((1)/(2))d\theta . If 0 < e < 1, this integral cannot be integrated in terms of “well-known” functions. However, fnInt, may be used...
