Question

I'm not sure how bond legnth affects how to tell if there's a resonance structure or not. we had to use a computer program to view a 3D model that showed us bond legnth in class. I'm also not sure why Sulfur can hold so many electrons and if that and hybridization has to do with what the question asks..?? I'm so confused, thank you ??... the question is in the photo

Lab 5 Homework Make sure to completely answer each of the following questions. This will be due at the start of the following lab. Support each answer with data and observations from this laboratory exercise. Include Lewis structures and/or sketches of the molecules that show geometry as necessary. 1. Shown below are the structures of sulfuric acid, H2SO4, and sulfate, SO42, showing the lengths of bonds in nm. Does sulfate exist as a resonance hybrid? What's the evidence? Explain your decision citing evidence from Part A. 0.098 nm 0.145 nms 0.163 nm 0153 notis3 nm 0163 0145 nm 0:153 nm 0.153 nm 0.098 nm Sulfuric Acid Sulfate H- 0-s-o-H O=0= 0 2.

Bond length Explanation - Due Due to to reesonance reason once of of so- ion of s=o' bond 504 son getro single bond character and go bond gets doulele bond character. For this reason so- iom han all equal bond length. on the other hand, 42504 has no such significant resonance so. here all bond lengths are not equal cie. bond lengthers are different). SOA
