B KOH
I would say this is the base for the compound substance
Fluorine in compounds is always assigned an oxidation number of -1
Answer:
fe3o4+4h2 - 3fe + 4h2o
therefore coefficient is 4
Answer:
pOH= 14.248
[H+]=1.77 M
[OH-]=5.65 x10^-15M
Explanation:
pH+pOH= 14
pOH= 14-pH
pOH=14-(-0.248)
pOH= 14.248
[H+]=10^-pH= 10^-(-0.248)=1.77 M
[OH-]=10^-pOH= 10^-14.248=5.65 x10^-15M
