OK, so our teacher gave us these pics with 4 test tubes showing reactions with metals and dilute sulfuric acidOne had a LOT of fizz, the next had none, the third had only a few and the last had just a bit less than the firstShe told us the metals were iron, magnesium, X and YY was right below aluminium in the reactivity seriesFind X and YI know Y is ZincWhat is X??? ( You also needed to match the test tubes with the correct metal).
