One of the homework problems (#9 sixth edition) asks for the shape of ICl3, where iodine is the central atom. I thought the shape would be trigonal planar, but I see that the correct answer is t-shaped. What makes it t-shaped instead of trigonal planar?
I'm a little confused because I know that larger atoms have a larger distance and longer bond length, making them weaker bonds. However, I also have in my notes that increasing size or molar mass causes stronger interactions. Wouldn't stronger interactions mean a stronger bond?

I think I heard someone ask this question in lecture and he said that he doesn't expect us to memorize it now, but it sounded like we may need to be more familiar with it later.

Handwritten works best for me because I feel like it helps to get used to writing out the notation as you would have to do on a test. I also try to make an effort of keeping things neat and spaced out so that when I refer back to my notes it's legible.
This question gives us the molar mass metal hydroxide M(OH)2 is 74.10 g/mol. Then it asks what the molar mass of the sulfide of this metal. Sounds simple, but I'm confused on where the sulfide comes from. Anyone know what it means?
