The elements within a group in the table have similar properties. ... In general, how can the periodic trends displayed by elements be explained? What is the underlying cause of periodic trends? Trends in atomic size, ionization energy, ionic size, and electronegativity can be explained by variations in atomic structure.
In liquids, particles are slightly spaced from each other and move around somewhat freely, but still bump into each other. Gases on the other hand move randomly and rarely bump into each other, thus they are more spaced out.
Answer: pOH = 3.13
Ba(OH)2 is a very basic substance. The general formula for pOH is - log(OH)
Barium Hydroxide produces 2 moles of OH for every mole of Ba(OH)2 present in the solution.
0.00037 M = 3.7 * 10^-4 Ba(OH)2 will produce 2 *0.00037 M of OH-
OH- = 2* 0.00037 = 0.00074
pOH = - log(0.00074) = 3.13
