You must Use Hess's Law to determine the enthalpy change for the following reaction P4O10(s) --> P4(s)+ 5O2(g) delta H = +2967 KJ {#2 reversed} 6PCl5 --> 6PCl3 + 6Cl2 delta H = +504 kJ {#3 reversed and multiplied by 6} P4 + 6Cl2 --> 4PCl3 delta H = -1226 kJ {#1 used as is} 10PCl3 + 5O2 ---> 10POCl3 delta H = -2860 kJ {#4 multiplied by 10} ______________________________________ {added together}
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
