2- Gases A2 and B2 react according to the equation: A2 + B2 → AxBy . 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...

KMnO4 and H2C2O4 react according to the following balanced equation: 2 KMnO4 + 5 H2C2O4 + 3 H2SO4 --> 2 MnSO4 + 10 CO2 + 8 H2O + K2SO4. If 17.45 g of KMnO4 (MW = 158.03 g/mol) react with 28.85 g H2C2O4 (MW = 90.03 g/mol) how many grams of H2C2O4 will remain at the end of the reaction in the presence of excess H2SO4? Enter your answer to two decimal places.

In Python iOverlap (a1, a2, b1, b2) Write the function iOverlap that tests whether 2 closed intervals overlap. It takes 4 numbers (ints or floats) a1, a2, b1, b2 that describe the two closed intervals [a1,a2] and [b1,b2] of the real number line, and returns True if these two closed intervals overlap (even if at only one point) and False otherwise. If a1>a2, then the interval [a1,a2] is empty. If b1>b2, then the interval [b1,b2] is empty. Both intervals are...
