Answer:
See explanation below
Explanation:
If [OH | = 1x 10^-7 M then [H^+] = 1 * 10^-14/1x 10^-7 = 1x 10^-7 M
pH = - log [H^+] = -log [1x 10^-7]
pH = 7
If [OH | = 1x 10^-9 M then [H^+] = 1 * 10^-14/1x 10^-9 = 1x 10^-5 M
pH = - log [H^+] = -log [1x 10^-5]
pH = 5
[H^+] = 1 x 10^-3 M
pH = - log [H^+] = -log [1x 10^-3]
pH = 3
Hence the decreasing acidity;
pH 3 > pH 5 > pH 7 > pH 11
The most acidic is pH 3 while the most basic is pH 11
The volume measurements won't be accurate and will be either less than or more than the anticipated figure if the graduated cylinder is accurately calibrated (depending on if the error in calibration is higher or lower). Depending on the calibration error, the calculated value may be higher or lower than the real value.
What is calibration?
Setting up an instrument so that it can generate findings for samples that fall within a tolerable range is part of the calibration process. A key component of instrumentation design is eliminating or reducing conditions that lead to faulty measurements.
Calibration attempts to reduce any measurement uncertainty by confirming the precision of test apparatus. In measuring procedures, calibration quantifies and reduces mistakes or uncertainties to a manageable level.

Noble gases hardly ever participate in chemical reactions because they already have 8 valence electrons and are the most stable among other elements.
Therefore, C. noble gases is the correct answer.
