Particles are the smallest units of any state of matter that moves in a medium due to various factors. The particle movement best supports the collision theory.
<h3>What is collision theory?</h3>
In a reactant, the particles move and collide with each other resulting in some amount of change and the collision between the atoms and the molecules are necessary for a chemical reaction to occur.
This theory of collision is used for the prediction of the rate of the reaction to occur and the chemical changes occurring in a gas or the reactant. This aids in understanding the rate of reaction occurring in a system.
The collision of the particles is proportional and related to the rate of the reaction. The amount of the concentration and their collision affects the rate at which the chemical change will occur.
Therefore, option A. the collision theory is supported here.

Answer:
Answer
The limitations are-
1. Privacy of the individuals involved in the research process.
2. Physical and psychological risks should be minimized
3. The subjects should be chosen equitably
4. Only reasonable exposure to risks is admissible.
Explanation
The privacy of the individuals involved in the research must be taken into consideration. This will ensure safety of patient data and information. The risk of physical and physiological well being of the person must be taken into consideration in such a research. In addition to that, the subject must be made to understand every procedure and the risks involved before testing. Moreover, only minimal exposure to risks is allowed and must have been previously tested in animals to avoid deaths.
Answer:
14 ft 7 inches
step-by-step explanation:
since each model inch corresponds to 25 real inches, 7 model inches will correspond to
7×25" = 175"
at 12" per foot, that is 14 feet, 7 inches.
