Consider the following reactions at $1000\,^oC$

$(I)$ $Zn(s) + \frac{1}{2}{O_2}(g)\xrightarrow{\Delta }ZnO(g);{\mkern 1mu} {\mkern 1mu} {\mkern 1mu} {\mkern 1mu} {\mkern 1mu} {\mkern 1mu} $      $\Delta {G^o} =  – 360{\mkern 1mu} \,kJ{\mkern 1mu} \,mo{l^{ – 1}}$

$(II)$ $C(s) + \frac{1}{2}{O_2}(g)\xrightarrow{\Delta }CO(g);{\mkern 1mu} {\mkern 1mu} $      $\Delta {G^o} =  – \,460{\mkern 1mu} \,kJ\,{\mkern 1mu} mo{l^{ – 1}}$

and choose the correct statement at  $1000\,^oC$

Give the correct order of initials $T$ or $F$ for following statements. Use $T$ if statement is true and $F$ if it is false.

$(i)$ $Cu$ metal is extracted from its sulphide ore by reduction of $Cu_2O$ with $FeS.$

$(ii)$ An ore of Tin containing $FeCrO_4$ is concentrated by magnetic separation method.

$(iii)$ Auto reduction process is used in the extraction of $Cu\, \& \,Hg.$

$(iv)$ Cassiterite and Rutile are oxide ores of the metals.

Blister copper is refined by stirring molten impure metal with green logs of wood because such a wood liberates hydrocarbon gases (like $CH_4$) . This process $X$ is called . . . . . . . . . and the metal contains impurities of $Y$ is …….. .

Which of the following metal produces $N_2O$ on reaction with $20\%\  HNO_3$ 

During extraction of $Fe$ which reaction performed in combustion zone?
