Now, I read the chapter but I'm missing where I was told the information I would need for these questions...

1. How could you determine if a silver liquid was Hg (a liquid metal) or melted Ag?

2. Many processes in our body, such as sweating, are controlled or limited by inhibitors. What do these molecules do?
Aw, I don't know, nothing about this was mentioned, I swear...I don't even know how this pertains to what I'm currently learning..."Chapter 2: Matter", physical properites, chemical properties, kinds of matter, etc. but nothing about the human body was mentioned.

1. How could you determine if a silver liquid was Hg (a liquid metal) or melted Ag?

Mercury is a silver liquid at room temperature and pressure.

2. Many processes in our body, such as sweating, are controlled or limited by inhibitors. What do these molecules do?

Read basic physiology.

the second question probably deals with catalyst...
