Consider the reaction of nitrous oxide N$_2$O  with oxygen O$_2$  to form nitrogen dioxide NO$_2$:
$$ \rm 2N_2O_{(g)} + 3O_{2(g)} \rightarrow 4NO_{2(g)}$$   A 5.0 liter vessel contains N$_2$O  gas at 5.0$\, atm$ pressure.  A second vessel, 2.0 L in volume contains oxygen at 5.0$\, atm$ pressure. Now suppose that the two vessels are connected by a pipe of negligible volume and the two gases mix and react to produce as much nitrogen dioxide as possible. Assume that the temperature remains constant.  What is the pressure in the apparatus at the end of the reaction?

\centerline{${\bf B} = 15{\bf i} +25{\bf j} -20{\bf k}$}\newline
The unit vectors in the x, y and z directions are {\bf i}, {\bf j} and {\bf k} respectively. {\bf A} is a displacement and has units of $\, m$, and {\bf B} is a force and has units of $\, N$. Calculate vector {\bf C} and enter the numerical values of its x, y, and z components.
