Homework Help: Help: Zn and HCI reaction rate.

  1. Apr 21, 2008 #1
    I need to check at what rate Zn and HCl react to release hydrogen gas.

    How do I construct a hypothesis?

    What method should I use?

    What would the variables be? (independent, dependent, and controlled)

    What relevance would all of this have to society?

    Please help.
