Materials provided:
    - copper, zinc, calcium 
    - magnesium nitrate solution

Rank the three metals from the most to the least reactive.  ]]> 2018-07-24 12:53:46 UTC https://padlet.com/k_pohkhee/8p4shpqijpos/wish/270977286 (B)(ii) k_pohkhee https://padlet.com/k_pohkhee/8p4shpqijpos/wish/270978477 An unknown metal Y is placed in three salt solutions (of M, N and L).

Results:
Visible reaction is observed in the test-tube containing N and L.

State two conclusion (in terms of the order of reactivity) of the four metals.]]> 2018-07-24 13:09:22 UTC https://padlet.com/k_pohkhee/8p4shpqijpos/wish/270978477 (A) k_pohkhee https://padlet.com/k_pohkhee/8p4shpqijpos/wish/271728052 Using ideas acquired from Activity 1 and 2, where will you place 'hydrogen' in the reactivity series? ]]> 2018-08-02 01:52:54 UTC https://padlet.com/k_pohkhee/8p4shpqijpos/wish/271728052
