How much PV work is done if 88.0 grams of C 2H 4 ethylene and 120 grams of hydrochloric acid HCl are permitted to react at atmospheric pressure and the volume change = -70.3 Litres? Express your answer in kilojoules?
Show that the ammonium ion NH4+, 1ppb(mole fraction) is equivalent to 0.56 ppb (mass fraction) or .74 ugm-3 at T=298 and 1 atm. Start by solving for mass concentration Note that mass fraction is related to mole fraction as
Constant external pressure of3.00 atm, followed by2) against a constant external pressure of 2.00 atm. Calculate q and w. (101.33 J = 1 L atm)
What is the maximum mass of aluminum chloride that can be formed when reacting 29.0g of AL with 34.0g of Cl
Liquid helium at 4.20 K has a density of 0.147 g/mL. Suppose that a 1.50 L metal bottle at 110 K contains air at 3.0 atm pressure. If 50.0 mL of liquid helium are added to the bottle
the reaction must progress forward to attain equilibrium. The richer a reaction mixture is in product the higher its Q value is. The value of K does not change as a reaction progresses toward equilibrium.
