Question

Standard heat of formation of hydrazine $\left(N_2{H}_{4\left(I\right)}\right)$,hydrogen peroxide $\left(H_2{O}_{2\left(I\right)}\right)$ and water $\left(H_2{O}_{\left(I\right)}\right)$ are $50.4,-143.2$ and $-242.7KJ/mole$ respectively.Calculate he standard heat of formation for reaction.
$N_2{H}_{4_{\left(I\right)}}+2H_2{O}_{2\left(d\right)}$ $\to N_{2\left(g\right)}+4H_2{O}_{\left(I\right)}$

Answer 1

If uncertainty is not in debroglic wavelength
$△x=0$
$△x.△p\ge \frac{h}{4\pi }$
$△x.m△v\ge \frac{h}{4\pi }$
$△V\ge \frac{h}{4\pi m△x}$
if $△x=0$
$△V=\infty$
it will be totally uncertain
