D Question 6 1 pts Which of the following compounds is not miscible with water? O (CH3CH2)2NH ccle none of these CH3COOH оноснусн,он

Question 17 1 pts Which of the following statements regarding spontaneous changes is false? none of these O Spontaneity is favored when the dispersal of matter is increased. All exothermic reactions are spontaneous. Spontaneous changes occur at a given state without any outside influence. Spontaneity is favored when heat is released.
