A = h/2*(a + b) So 2A/h = a + b and therefore, a = 2A/h - b
2 and a half plus 3 and a half plus 4 and a half = 10.5
2 and a half plus 2 and a half plus 10 plus 10 = 25
This equals one and a half.
Oxidant half reaction: MnO4- + 8 H+ + 5e- --> Mn2+ + 4 H2O
4 and (not an!) a half.
One fourth plus one half plus one half plus 1 is equal to 2.25 or 2 1/4
2H
H
H+ or a proton.
(b+h)(b+h)= b2+2hb+h2.
:a = .5(hb+c) :2a = hb+c :2a−c = hb :(2a−c)/h = b
