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.
It is elastic potential energy

Fifth in line from the sun, Jupiter is, by far, the largest planet in the solar system.
Answer:
Hydrogen ions
Explanation: acids will produce hydrogen ions, I asked my teacher. Please tell me if we are wrong.
When you see or visit grasslands you know that :
- They have mild to hot summers ( B )
- They have a lot of precipitation ( A )
<h3><u>Grassland vegetation</u> </h3>
Grasslands are a type of vegetation found mostly in areas with favourable weather conditions such as mild summers and right amount of precipitation which provides the grasslands with enough water for proper growth.
Other types of vegetation include :
- Forest vegetation
- Tundra and
- Desert vegetation
Desert vegetation expreciences very hot summers and little precipitation which leads to the scarcity of green vegetation, while forest vegetation expreciences a very high level of precipitation.
Hence we can conclude that When you see or visit grasslands you know that :They have mild to hot summers ,They have a lot of precipitation
