Question:
(a) Structures 16.67 and 16.68 show hypervalent sulfur in NSF and NSF3. Draw resonance structures for each molecule that retains an octet of electrons around the S atoms, and account for the three equivalent S—F bonds in NSF3.
(b) The enthalpies of vaporization (at the boiling point) of H2O, H2S, H2Se and H2Te are 40.6, 18.7, 19.7 and 19.2 kJ mol−1. Give an explanation for the trend in these values.
(c) Which of the following compounds undergoes significant reaction when they dissolve in water under ambient conditions: Al2Se3, HgS, SF6, SF4, SeO2, FeS2 and As2S3? Give equations to show the reactions that occur. Which of these compounds is kinetically, but not thermodynamically, stable with respect to hydrolysis?

Before working at Mariakani, I volunteered at a local community center, where I tutored students from diverse backgrounds. I helped them improve their academic performance and develop self-esteem and confidence. I used creative teaching methods, such as role-playing and group discussions, to make the learning experience more engaging and enjoyable.
In addition, I have conducted workshops and training sessions for educators and mental health professionals on various topics related to counseling and psychology. I have presented research papers at conferences and published articles in academic journals.
Overall, I am passionate about sharing my knowledge and helping others achieve their goals. I believe that tutoring is an excellent way to make a positive impact on people's lives, and I am committed to providing high-quality, personalized instruction to my students.
