i belive it gold.
Magnesium, Iron, Copper. Most reactive - least reactive.
Helium is least reactive element.It forms no compounds.Platinum is least reactive metal.
Magnesium is more reactive than copper because if you study the periodic table, you will be able to find out that Magnesium is more reactive.Also, coins are made out of copper, they choose copper because it is cheap and extremely unreactive.Furthermore, I've done an experiment to find out that Magnesium is more reactive than Copper by putting both elements into Water/Acid.
because magnezium is more reactive
Sodium is by far the most reactive. It self ignites in air (it is stored in oil), reacts vigorously with water (releasing hydrogen) and reacts explosively in acids-even dilute. But the most reactive metal is Cesium and the most reactive non-metal is Flourine Cesium and H20 will explode...
Magnesium, Iron, Copper. Most reactive - least reactive.
Hydrogen is more reactive than Copper, but less reactive than Zinc which is less reactive than Magnesium which is less reactive than Potassium. Potassium is the most reactive of all, relatively speaking.
the diffrences in reaction of potassium, magnesium and copper
Mix magnesium powder with copper sulphate. The more reactive magnesium will displace the less reactive copper.
Magnesium
Magnesium is more reactive than copper, so it will displace (swap places) with the copper forming magnesium sulphate and copper.
sodium, calcium, magnesium, aluminium, zinc, iron, tin and led are metals more reactive than hydrogen.
magnesium is more reactive than copper so,it displaces copper from its salt solution.
They could, since magnesium is more reactive than copper, and could displace it to form magnesium nitrate.
This is a simple displacement reaction - the more reactive magnesium displaces the less reactive copper from a solution of its salt. .... magnesium + copper sulphate ---> copper + magnesium sulphate Mg + CuSO4 ----> MgSO4 + Cu the blue colour of the copper sulphate will disappear and the silver coloured magnesium will be replaced by brown-red copper metal. Hope this helps. :)
magnesium is most reactive
Copper metal is less reactive than potassium so it will not react with potassium cyanide.
