metal oxide
a metal that has bonded with oxygen after being heated
displacement reaction
a more reactive metal takes the place of a less reactive metal, making the more reactive metal a compound while the less reactive one becomes an element
a salt
when an acid and a metal react, the hydrogen in the acid is replaced by a metal, therefore making this compound
metal hydroxide + hydrogen gas
produced by reacting very reactive metals with cold water
the set up in which magnesium can be reacted with steam
a glass tube with a magnesium ribbon and a piece of mineral wool soaked in water inside, which is clamped and heated with a Bunsen burner
test for hydrogen
when reacting a metal and a salt, the gas can be collected in an upturned test tube. If a lit splint is inserted and is followed by a squeaky ‘pop’ sound, the gas tested for is present.
three main acids
hydrochloric acid, sulfuric acid, nitric acid
metals which are more reactive than hydrogen (decreasing reactivity)
potassium, sodium, barium, calcium, magnesium, aluminium, zinc, iron, nickel
metals which are less reactive than hydrogen (decreasing reactivity)
copper, mercury, silver, gold, platinum
Salt and hydrogen gas
Produced when metal is reacted with an acid
