You can end a chapter in one of three ways.
The turn - a change of emotion that turns the preceding mood on its head - example. A chapter about the sadness of a funeral that ends in a couple of kids laughing. (This is the most common, especially among script-writing).
The hang - A piece of information that will be revealed later in the novel - example. She would find out why she had this premonition when she grew old.
The sequence - Not to be confused with the hang, but an issue that will be picked right up in the next chapter. Chapter 2 (ending) - She wasn't sure if she would pick up the flower, but she doubted it. Chapter 3 (beginning) - the rose felt like rough silt between her fingers.
Ending a chapter is key to writing a novel.
