Given the following reactions:

$171,98kj$ of heat is required to convert a given amount of FeO to$.$ Fe$.$ Calculate the amount of $H_{2(g)}$ in likers that mill be produced at STP if all the Fe produced by the first reaction is reacted with $HCl.$

a$)30,1$

b$)90,3$

c$)60,2$

d$)32,7.$

e$)65,4$

Calculate $H{F}_f$ for $($s$),$ given the following thermo chemieal data... &

$2H_{2(g)}+O_{2(s)}$longrightarrow$2H_2{O}_{(2)}.$

$2Ca{O}_{(s)}+2H_2{O}_{(1)}$longrightarrow$2C{a}^{-}(OH{)}_{2(s)}$

CaO$(s)longrightarrowCa(s)+\frac{1}{2}{O}_2(g).$

$H=-570kj$

$H=-128kj$

$H=+635kj$

a$)-414k\frac{j}{m}ol$

b$)-984k\frac{j}{m}ol$

c$)-286k\frac{i}{m}ol$

d$)+984k\frac{j}{m}ol$

e$)+4143k\frac{j}{m}ol$
