    Chemistry Speech - Urgent Help!!

    I've got a speech next week upon this topic "outline examples of the selection of metals for different purposes based on their reactivity, with a particular emphasis on current developements in the use of metals". If any-one can help in any matter, little or large, it will be highly beneficial and indeed i would be very grateful. The speech is about the 4 minute guideline. Thanks in advance.

    Look up uses for stainless steel, aluminum, chromium. Compare with iron or copper. Also look up uses for zinc.

    The first three metals above (along with the noble metals) are chemically inert, for different reasons. That makes them useful in various areas. Iron and copper are not so inert, and hence...

    And zinc is fairly reactive, making it useful in a different way.

    Looking at the discoveries, uses and even the prices (over time) of these metals is also quite an interesting study.

    To tell you any more would be doing your work for you.
