Answer:
Explanation:an element (e.g. arsenic, antimony, or tin) whose properties are intermediate between those of metals and solid non-metals or semiconductors
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

A hot filtration should be used in the process of Crystallization.
<h3>What is Crystallization?</h3>
This is the conversion of a chemical in liquid form to a crystalline solid. The crystal formed are repeating three-dimensional pattern or lattice.
Hot filtration is used in the process of Crystallization of a solid which contains impurities that are insoluble in the crystallization solvent and also to remove highly colored impurities from a solid.

Because chemistry is a new science , a lot of new information that is hard to understand for most students. If one doesn't study enough or put the work in to understand all the new concepts and such , it's hard to pass the class :(
