Calculate the pOH of a solution that is 2.08x10-9 M of Potassium hydroxide (KOH). pOH = (round to 2 decimal places)

passing a magnet thought the

mixture , because iron gets attracted to magnet .

dynamic equilibrium is the answer.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer
