the reactivity series

Question 1

what’s the equation for a metals reactions with water

Answer 1

metal + water —> metal hydroxide + hydrogen

Question 2

describe the reactivity series between the reactions of group 1 metals

Answer 2

potassium reacts vigorously, rapidly with water

sodium reacts less rapidly with water than potassium

lithium reacts more slowly than either potassium or sodium

Question 3

Reactivity series of metals with water at room temperature

Answer 3

potassium___
sodium | reacts very rapidly
lithium_______|with water at room temperature

calcium —— reacts quite rapidly with water at
room temp

magnesium____
zinc |. No reaction with water at
iron. | room temperature
copper_________|

Question 4

some metals have no reaction with water at room temp, what do we react them with to investigate their reactivity

Answer 4

dilute acids

Question 5

reactivity series of metals with acids are:

Answer 5

potassium___
sodium | dangerously fast reaction with
lithium_______| acids

calcium —— extremely vigorous reaction

magnesium —— Rapid reaction
zinc —— quite rapid reaction
iron —— quite slow reaction
copper —— no reaction

Question 6

The reactivity series used for all reactions is:

Answer 6

please=potassium
stop=sodium
calling=calcium 
me=magnesium
a=aluminium
careless=carbon
zebra=zinc
intead=iron
try=tin
learning=lead
how=hydrogen
copper=copper
saves=silver
gold=gold

Question 7

what determines how rapidly a metal reacts

Answer 7

the ability to lose electrons and form positive ions

Question 8

what is the equation for a reaction of metal , potassium losing its electron

Answer 8

K —> K+ + e-
