Syngas $($a combination of carbon monoxide, $CO,$ and hydrogen gas, $H_2)$ can be produced by reacting methane $(C{H}_4)$ with steam $(H_{2}O(g)).$ If the standard industrial process has a $87\%$ yield using excess steam, how many kilograms of hydrogen will be produced from $150kg$ of methane?

a$)49$

b$)12$

c$)56$

d$)120$

e$)74$

Question $3(1$ point$)$

A $100\mathrm{.}0mL$ nickel container is filled with $5\mathrm{.}00{10}^{-3}$mol of $xe(g)$ and $4\mathrm{.}07{10}^{-2}$ mol of $F_2(g)$ at $25\mathrm{.}0C.$ After reacting the gases, $xe{F}_6(g)$ was produced. What was the final total pressure $($in bar$)$ in the vessel at $25\mathrm{.}0C?$

$4\mathrm{.}29$

$7\mathrm{.}01$

$11\mathrm{.}3$

$4\mathrm{.}97$

$7\mathrm{.}61$ Solve both with full steps please.
