10. In terms of annual production, nitric acid, HNO$_3$, is one of the top ten industrial chemicals in North America. It is used in the production of fertilizers such as ammonium nitrate, and explosives such as nitroglycerin. The first step in the manufacture of nitric acid by the Ostwald process is the reaction between ammonia and oxygen, in the presence of a catalyst. The equation for the reaction is as follows. NH$_3$ + O$_2$ $\rightarrow$ NO$_2$ + H$_2$O a) What mass of oxygen is required to completely react with 1.22 kg of ammonia? (4018g) b) What mass of NO$_2$ is produced at the same time? (3295g)

Texts: Q.2 For questions Q2a to Q2e, consider a submarine with a wall of 14 cm thickness where the heat flow is by conduction within the wall and by convection into the water must be evaluated. The properties of the wall are: Thermal conductivity k = 0.1 [W/mK], Density p = 300 [kg/m^3], Specific heat capacity Cp = 1000 [J/mK]. The finite difference explicit method was chosen for the analysis. The wall is discretized in one dimension in 15 control volumes. Control volumes at the boundaries have a thickness of 0.5 cm, and the ones inside the wall have a thickness of 1 cm each. Nodes for boundary control volumes are placed on the surfaces of the wall, and nodes are placed in the middle of control volumes inside the wall. All nodes are initialized at t = 0 s with a temperature equal to 10°C. Water temperature is shown in the table below. Time (s) Water temperature (°C) 0 10 30 9.7 60 9.4 90 9.1 Assume a convective heat transfer coefficient (h) of 100 [W/m^2K] between the wall and the water. Longwave radiation and shortwave radiation can be neglected. Use a time-step of 30 s. PLEASE TURN OVER ME404 Page 2 of 5 a) Evaluate if the solution for heat conduction is stable given the parameters above.
