Draw the Lewis structures for each of the following, determine the shape of the molecules.
and explain how do you determine the shape of it
We can't draw structures or Lewis dot structures on the board. Most of this you can find on the Internet by search on Google. For example, here is H2S.
can you explain how to determine the shape of it though?
Rules and introduction that is just too long to type in manually. Here is a good site that explains it. The introductory page comes up first (What is VSEPR), then you look on the left for the remainder of the information. Look at Rules and Counting Regions of High Electron Density. From there you get the shapes.
