1. A student wanted to measure the amounts of (Ca2+) in the human blood. She got 1.00ml which she treated with Na2C2O4 solution. The resulting Ca2C2O4 precipitate was filtered and dissolved in dilute H2SO4 to release C2O42- into solution and allow it to be oxidized. The ...

(1) Why are fractional coefficients permitted in a balanced thermochemical equation? In thermochemical reactions, only small amounts of matter are considered. If fractional coefficients were not used, the scale of the reaction would be excessively large. Fractional ...

Your post flawed. The equation you want is not balanced. It should be 2NO2(g) ==> N2(g) + 2O2(g) Take eqn 1, multiply by 2 and reverse it. k' for the new equn is 1/k^2. Add eqn 2 as is with k2. The K for the desired reaction is Kc = k2*k'.
