Entropy decrease during

What causes the entropy to change when a solute dissolves in a solvent?A.The solute becomes conductive.B.The solute changes the vapor pressure.C.The solute becomes less ordered.D.The solute changes the enthalpy.

Consider the entropy change in the following chemical or physical processes:2 Na(s)  +  Cl2(g)  →  2 NaCl(s)N2(g)  +  3 H2(g)  →  2 NH3(g)H2O(s)  →  H2O(l)C10H22(l)  →  C10H22(s)2 Mg(s)  +  O2(g)  →    2 MgO(s)In which of these processes is entropy increased?Question 8Select one:Entropy is increased in # 2 and # 3None. Entropy is decreased on all these processesEntropy is increased in #1, #4 and #5Entropy is increased in all five processes Entropy is increased in # 3 only.

What does a change in the entropy of a system indicate?A.That the activation energy has changedB.That the disorder of the system has changedC.That the energy of the system has changedD.That the equilibrium position has changed
