Patterns Of Reactivity Flashcards
Metal+oxide=
Metal oxide
Colour and description when copper is burned
Piece of copper turns black
Colour when iron is burned
Orange sparks
Colour when magnesium is burned
Bright white light
Order of reactivity most to least
Iron,magnesium,copper
Magnesium,copper,iron
What does potassium do when in contact with water
It catches fire and burns a lilac flame
What does sodium do when in contact with water
Sodium reacts vigorously and moves across the water
Why are sodium and potassium stored under oil in jars
They could react which the water/moisture in the air
Metal+water=
Metal hydroxide+ hydrogen
What happens when calcium reacts with water
Sinks and rises, bubbles of gas, vigorous reaction, calcium disappears at the end of the
What is the reaction of magnesium with water
A few bubbles of gas, reacts slowly
What is the reaction of copper with water
It doesn’t react
Calcium+water=
Calcium hydroxide+ hydrogen
Metal+acid=
Salt+hydrogen
What is produced when a metal reacts with a acid
Hydrogen gas and a salt
Which metals would you not put into acid
Potassium,sodium,lithium because they’re explosive
What is the reaction of aluminium with water and acid
With water it reacts slowly but with acid it reacts vigorously
List metals so far from most reactive to least reactive
Potassium
Sodium.
Lithium.
Calcium
Magnesium
Aluminium
Zinc
Iron
Tim
Lead
Copper
Silver
Gold
What does aluminium have that most metals don’t
It has a coating of aluminium oxide on its surface which prevents it from reacting quickly
Magnesium+sulfuric acid=
Magnesium sulfate+hydrogen
