Ammonia and hydrogen combustion $($Task $1$ a$-$e Exam PEF$21062020)$

Using ammonia as an alternative fuel can revolutionize the maritime industry.

a$)$ Balance the stoichiometric equations; NH$3+$ a$1($O$2+3\mathrm{.}76$N$2)->$ b$1$ H$2$O $+$ c$1$ N$2$

b$)$ How much water $($kg$)$ is produced per kg NH$3$ when we burn NH$3$ with air?

$($MWH $=1$ kg$/$kmol$,$ MWN $=14$ kg$/$kmol$,$ MWO $=16$ kg$/$kmol$)$

c$)$ The heat of formation $(1$ atm and $25)$ for gaseous water, H$2$O$($g$)$ is $-241\mathrm{.}83$ MJ$/$kmol$,$ and for NH$3($g$),45\mathrm{.}92$ MJ$/$kmol$.$ Use the heat of formations and calculate the heat of combustion $($Lower Heating Value$)$ for NH$3.$

d$)$ What is the adiabatic flame temperature for stoichiometric NH$3-$Air at $25$ and $1$ atm when we assume complete combustion and the product's average cp $=1\mathrm{.}45$ kJ$/($K$$kg$).$

e$)$ Find the heat of combustion per m$3$ stoichiometric fuel$-$air mixture $($i$.$e$.,$ MJ$/$m$3$ mix$)$ at $1$ atm and $25$ for NH$3$ as fuel. $($Air has a density of $1\mathrm{.}18$ kg$/$m$3$ at $1$ atm and $25)$
