need both questions thank you
12. (a) (20 pts) Thiosulfate, S, 0%, is just like sulfate, except that one oxygen atom in sulfate has been substituted by sulfur. Draw one correct Lewis structure for thiosulfate, showing all lone pairs and all formal charges, if different than zero. (b) (10 pts) Keeping in mind our stated ideas about how to optimize Lewis structures for atoms like P, S, As etc. that do not have to follow the octet rule, how many...
