Answer:
<em>The solution with the lowest pH is 0.1 M HCl.</em>
Explanation:
Since the three solutions have the same concentration (0,1M) it is only necessary to look at the pKa of each solution.
Also, knowing that a higher pKa means a lower Ka, because pKa = -Log (Ka). Thus, a lower Ka means a lower concentration of protons with a higher pH ( pH = -Log [H+].
The HCl doesn't have a pKa because is a strong acid that dissociates completely. Therefore, this solution produces a lower pH. Looking at the pKa of acetic acid and formic acid solutions, the second with the lowest pH is the formic acid solutions and the higher pH is for the acetic acid solution.
False. Sarah has not achieved homeostasis.
<h3>What is homeostasis?</h3>
It is the maintenance of a relatively unchanged internal process in the body of organisms.
Since the resting heart rate for Sarah is 70 bpm, a 100 bpm is a far cry from the normal resting heart rate.
Thus, it cannot be said that Sarah has achieved homeostasis.

Real quick, I will tell you why i think it does from a scientific point of veiw, but I dont know for sure.
The reason that the Earth goes through so much change on a regular basis is because of Gravity. What Gravity is doing is pulling objects to the Earth that it can reach (Which you probably knew) and so when it does this, it is pulling at the earths surface as well, causing constant change.
I hope this helps you!
