level questions: Reactivity of Metals

QuestionAnswer
What determines how Reactive a Metal is?-It all comes down to how easy it is to lose the Outer Electrons. Easier = More Reactive
How can the Reactivity of Metals be shown? Use example with Magnesium, Zinc and Copper-Simply place some Metals into Dilute Hydrochloric Acid eg -Then, with a burning splint test, the Noise of the 'Pop' will determine how Reactive it is. -Magnesium would have a very loud Pop, mainly because its a Group 2 Element, which are more Reactive naturally -Zinc would have a Pop, but quieter then Magnesium -Copper would have Nothing, its Very Unreactive -More Reactive a Metal is - the Faster the Reaction
How would the Rate of the Reaction change if the Metal is more Reactive [Metal + Hydrochloric Acid]-Faster. More reactive metals makes the Reaction more Faster, and with more Aggression -You can also Visually see this, by the Bubble Rate, Faster Bubbles spawn in = Faster the Reaction = More Reactive Metal
What happens, if a Metal Reacts with Water? Show the FormulaMetal + Water --> Metal Hydroxide + Hydrogen OR Metal + Steam --> Metal Oxide + Hydrogen [For a Lesser Reactive Metal]
How can a Metal reacting with Water/Steam show how Reactive it is? -What happens if Potassium, Zinc and Copper react with Water/Steam-The more Violent the Reaction is, the more Reactive it is -Potassium will react Violently with the Water, making it a Reactive Metal, which it is -Zinc won't really do much with Water, but with Steam it can play around more [It can React with Steam] -Copper literally will do Nothing. Easy
What is the Reactivity Series?-This is simply a Table, that orders the Metals from Most Reactive, to Least Reactive.
Show the Reactivity Series, from Most Reactive downwards:Potassium, K [Most Reactive] Sodium, Na Calcium, Ca Magnesium, Mg Aluminium, Al Zinc, Zn Iron, Fe Copper, Cu Silver, Ag [Least Reactive]
What would happen, if Iron is placed in a Solution of Copper Sulphate? -Give the Formula-This would become a Displacement Reaction -Since Iron is more Reactive [Reactivity Series] it will 'Kick' out the Copper from the Sulphate, making Iron Sulphate and leaving Copper on its own Copper Sulphate + Iron --> Iron Sulphate + Copper
What would happen, if Silver is placed into a Solution of Copper Sulphate? -Give the Formula-This would result in Nothing Happening -Since Copper is more Reactive [Reactivity Series] it will stay on to the Sulphate, so Silver will simply just do whatever in it Silver + Copper Sulphate --> Copper Sulphate + Silver
