Mass number is the total number of protons and neutrons in the nucleus
Answer: 6.75 moles
Explanation:
This is a simple stoichiometry proboe. that I would set up like this:
(13.5 moles CuCI2) (1 mol I2 / 2 moles CuCi2)
That means you all you have to do for this problem is divide by 2 and cancel out the unit moles CuCI2, which leaves you with 6.75 moles I2.
Hope this helps :)
Answer: a low
and low pH.
Explanation:
pH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydrogen ion concentration.
![pOH=-log[OH^-]](https://tex.z-dn.net/?f=pOH%3D-log%5BOH%5E-%5D)
Thus as pOH and
are inversely related, a solution having higher pOH will have less amount of
concentration. And a solution having more pOH will have less pH.
Thus a substance with a high pOH would likely have low
concentration and low pH.
