The formula for pOH is -log(M)
So, all we need to do is plug in that number! -log(4.5x10^-3)
That gives us 2.3, so the pOH is 2.3 :)
Identify and name the cation; this is a metal element or polyatomic cation.
Identify and name the anion; this is a nonmetal element. Change the suffix to '-ide,' or use the polyatomic anion name.
2Al + 3Fe(NO₃)₂ = 3Fe + 2Al(NO₃)₃
m=245 g
w=0.805 (80.5%)
M{Fe(NO₃)₂}=179.857 g/mol
M(Fe)=55.847 g/mol
1. the mass of salt in solution is:
m{Fe(NO₃)₂}=mw
2. the proportion follows from the equation of reaction:
m(Fe)/3M(Fe)=m{Fe(NO₃)₂}/3M{Fe(NO₃)₂}
m(Fe)=M(Fe)m{Fe(NO₃)₂}/M{Fe(NO₃)₂}
m(Fe)=M(Fe)mw/M{Fe(NO₃)₂}
m(Fe)=55.847*245*0.805/179.857= 61.24 g
Anatomy I think it's important to know anatomy as a young adult so u are self aware of your body
