Here are four observations of the reactions of four metals.
Metal F and G react slowly with water Metal H displaces metal G from its chloride salt solution Metal E does not react with dilute acids Metal H does NOT displace metal F from its sulphate salt solution.
What is their order of reactivity, starting from the most reactive metal to the least reactive metal?
F>H>G>E; H>G>F>E; H>E>F>G; G>H>F>E; None of these
I'm really unsure how to order them I would say F>H>G>E but thats half guessing. Can someone give me a clue to arrange them right?
