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
This equals one and a half.
2 and a half plus 2 and a half plus 10 plus 10 = 25
the question is: C2H4 + MnO4- + H+ -> CO2 + Mn2+ + H2O the answer is: C2H4 -> CO2 feedback: The oxidation half-reaction includes only the species that is oxidized. Since the oxidation number of C goes from -2 to +4, it is oxidized.
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
Oxidant half reaction: MnO4- + 8 H+ + 5e- --> Mn2+ + 4 H2O
30 divided by .5 plus 10 equals 70 70
H+ or a proton.
