The original question is to find the pH and the pOH of 0.023 M of perchloric acid.
Answer:
pH = 1.638
pOH = 12.362
Explanation:
1- getting the pH:
pH can be calculated using the following rule:
pH = -log[H+]
Since the given solution is an acid, this means that [H+] is the same as the concentration of the solution.
This means that:
[H+] = 0.023
Substitute in the above equation to get the pH as follows:
pH = -log[0.023]
pH = 1.638
2- getting the pOH:
We know that:
pH + pOH = 14
We have calculated that pH = 1.638.
Substitute in the above equation to get the pOH as follows:
pOH + 1.638 = 14
pOH = 14 - 1.638
pOH = 12.362
Hope this helps :)
Pressure caused by high temperatures are balanced by gravity
Answer:
Corn stalks
Explanation:
Biomass fuel is produced by living or once-living organisms.
The most common biomass fuels used for energy come from plants, such as corn and soy.
B is wrong. Yellowcake is a refined form of uranium ore.
C and D are wrong. Coal and natural gas are not biomass fuels.
