Answer 5

hi

Answer 6

do you know how to rewrite the equation using formula??

Answer 7

\[\huge\rm \Delta H= H_{Product}- H_{reactant}\]

Answer 8

\[\large\rm\color{blue}{ P_4} +\color{red}{3}\color{blue}{O_2} \rightarrow \color{blue}{ P_4 O_6}~~~~\Delta H=-1640.1 KJ\]
the equatin is
\[\large\rm \rm H_{\color{blue}{P_4O_6}} - H_{\color{blue}{P_4}}-\color{ReD}{3} H_{\color{blue}{O_2}}=-1640.1\]
first write the products and then subtract reactants
2nd) any term with single element (not the compounds) or any diatomic elements will be 0
so
\[\large\rm \rm H_{\color{blue}{P_4O_6}} - \cancel{H_{\color{blue}{P_4}}}-\cancel{\color{ReD}{3} H_{\color{blue}{O_2}}}=-1640.1\]
Therefore,
\[\rm H_{\color{blue}{P_4O_6}}=-1640.1 KJ\]
now write the equation for 2nd reaction
