A rigid cylinder with a movable piston contains a sample of hydrogen gas.
330 K this sample has a pressure of 150 K PA and a volume of 3.50 L. What is the volume of the sample at STP

If a reactant was removed, did the new equilibrium system shift to make more reactants or more products?

Which substance has non polar covalent bonds

There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. in the first step, calcium carbide and water react to form acetylene and calcium hydroxide: cac2 (s) + 2h2o (g) → c2h2 (g) + caoh2 (s) =δh−414.kj in the second step, acetylene, carbon dioxide and water react to form acrylic acid: 6c2h2 (g) + 3co2 (g) + 4h2o (g) → 5ch2chco2h (g) =δh132.kj calculate the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide from these reactions. round your answer to the nearest kj .
