POH = - log [ OH-]
pOH = - log [ 1 x 10⁻¹²]
pOH = 12
T'belongs to the hydrides, it's a nitrogen hydride.
When the balanced reaction equation is:
2HCl(aq) + Ca(OH)2(aq) → CaCl2(aq) + 2H2O(l)
from the balanced equation, we can get the molar ratio between HCl & Ca(OH)2
2:1
∴ the volume of Ca(OH)2 = 15.8 L HCl * 1.51 m HCl * (1mol Ca(OH)2/ 2mol HCl) * (1L ca(OH)2/0.585 mol Ca(OH)2
= 20.4 L
3 NaOH + FeBr3 = 3 NaBr + Fe(OH)3
Hope this helps!!
