Determine ΔG° for the following reactions. All answers are two 2 significant figures. (a) Hg2+(aq) + 2 Ag(s) → Hg(l) + 2 Ag+(aq) WebAssign will check your answer for the correct number of significant figures. kJ (b) H2(g) + Cu2+(aq) → Cu(s) + 2 H+(aq) WebAssign will check your answer for the correct number of significant figures. kJ (c) 2 Fe3+(aq) + Pb(s) → 2 Fe2+(aq) + Pb2+(aq) WebAssign will check your answer for the correct number of significant figures. kJ

At 20°c, a sample of h2o liquid and a sample of co2 gas each have the same average kinetic energy. why is one a liquid and the other a gas at this temperature?

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.

Which of the following is a conclusion that resulted from ernest rutherford’s scattering experiment? (will mark brainliest) a. the nucleus is negatively charged b. the atom is a dense solid and is indivisible c. the mass is conserved when atoms react chemically d. the nucleus is very small and the atom is mostly empty space
