Hi everyone here we have a question telling us that the average bond until peace for X and X bonds are nitrogen to hydrogen 391.0 kg per mole nitrogen to nitrogen, 163.0 kg joules per mole. And our goal is using these bonding therapies to calculate the entropy of Adam Ization for hydrazine into H4, So into H Is going to equal one nitrogen to nitrogen bond plus four nitrogen to hydrogen bonds. So that will equal one times 163 zero killed joules per mole plus four Times 391 zero kg per mole. And that equals 1,727 kg per mole. And that is our final answer. Thank you for watching. Bye.
