Need help with these ideal gas law questions.
A quantity of CO gas occupies a volume of 0.63 L at 2.0 atm and 337 K. The pressure of the gas is lowered and its temperature is raised until its volume is 3.0 L.
Complete the mechanism for the reaction between acetophenone in acid and chlorine by adding the missing bonds, atoms, charges, nonbonding electrons and curved arrows forward reaction only.
A student attempted to identify an unknown compound by the method used in this experiment. she found that when she heated a sample weighing 0.4826 g, the mass barely changed, dropping to 0.4855 g.
Give the conjugate acid of the following Bronsted-Lowry bases. (Type your answer using the format [OH]- for OH -.) (a) HAsO42- (b) F - (c) S2- (d) OH-
what volume of nitrogen gas is needed to react completely with 150.0 L of hydrogen in the production of ammonia.
At 20 degrees C, 0.164 mg of H2 dissolves in 100.0 g of water when the H2 pressure above the water is 1.000 atm. Find the Henry's law constant for H2 is water at 20 degrees C.
A cylinder with a moveable piston contains 0.84 mol of gas and has a volume of 328 mL. What will its volume be if an additional 0.27 mol of gas is added to the cylinder? (Assume constant temperature and pressure.)
Silver forms face-centered cubic crystals. The atomic radius of a silver atom is 144 pm. Draw the face of a unit cell with the nuclei of the silver atoms at the lattice points. The atoms are in contact along the diagonal. Calculate the length of a..
The decomposition of DDT is a first order process with a half-life of 56.0 days.
The pKb values for the dibasic base B are pKb1 = 2.1 and pKb2 = 7.6. Calculate the pH at each of the following points in the titration of 50.0 mL of a 0.95 M B(aq) with 0.95 M HCl(aq).
Calculate DG for the reaction CS2 +3 CL2 -> S2CL2 + CCL4 given DH =-231.1 kJ and DS= -287.6 J/k - The answer is -145.3 Kj please show work as to how they got this answer.
