Collision theory states ..1. the most probable single step reaction is a termolecular (trimolecular) reaction. 2. all reactions have at least two transition states. 3. a reaction can be stopped in the middle to collect transition states. 4. molecules must interact with sufficient energy and in the correct orientation in order to react.

the answer would be a

the answer is 3.1 his answer is wrong mines is right

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
