The [ H3O+] of a solution with pH = 5.60 is ________.

Two of the hydrogen atoms in 5-FU are each bonded to one of the two nitrogen atoms in the molecule. Is it possible that the H in this N–H bond can form a hydrogen bond with a water molecule in solution? 

One of the components of cisplatin is ammonia. Draw the Lewis structure of ammonia and identify the central atom hybridization, the molecular shape of the molecule, and classify the molecule as polar or nonpolar. Draw the Lewis structure on a separate piece of paper and upload a photo of your response at the end of the test. Please mark the problem clearly and show your work. Enter the following information in the box below.  Central atom hybridization: Molecular shape: Molecular polarity:  polar or nonpolar
