I'm a pharmacy dispenser which is the same thing. what's your question?
Answer:
Simple Diffusion
Explanation:
Simple diffusion is the physical process by which substances move from a region where they are highly concentrated to areas where the concentration of that substance is lower. Simple diffusion is a spontaneous process that does not require energy, but is promoted by a concentration gradient.
The substances that are dissolved are called solutes, they move through a solution (or a gas) by random movements. Random motion is defined as the motion that occurs by chance, where there is no regular order or system by which the motions of the particles change in a solution or gas.
Diffusion is the net movement from an area of higher concentration to an area of lower concentration. The mechanism by which this happens is the random molecular motion: the right answer is " <span>Diffusion is
the movement of molecules from an area of lower concentration to one of
higher concentration by random molecular motion"</span>
Answer : The concentration of ion is, 0.00371 M
Explanation :
First we have to calculate the concentration of ion.
The solubility equilibrium reaction of will be:
The expression for solubility constant for this reaction will be,
Now we have to calculate the concentration of ion.
The solubility equilibrium reaction of will be:
The expression for solubility constant for this reaction will be,
Thus, the concentration of ion is, 0.00371 M
Answer:
D
Explanation:
The answer will be D because as we can deduct from the hypothesis, he will try to control the amount of food he gives the rats in order to see if in fact the fue of the mouse will be shinier
