metals Flashcards
metals able to displace h2 from cold water
potassium
sodium
calcium
magnesium
metals able to displace h2 from steam (decreasing vigour)
potassium sodium calcium magnesium aluminium zinc iron
product when h2 is displaced from cold water
metal hydroxide
product when h2 is displaced from cold water
metal hydroxide
metal oxides which do not decompose upon heating
all except silver, gold
metal hydroxides which do not decompose upon heating
potassium
sodium
effect of heat on metal hydroxides below sodium
decomposes to form metal oxide and water
metal carbonates which do not decompose upon heating
potassium
sodium
effect of heat on metal carbonates below sodium
decomposes to form metal oxide + co2
effect of heat on metal nitrates (potassium, sodium)
decomposes to form nitrite + o2
effect of heat on metal carbonates below sodium and above silver
decomposes to form oxide, co2
effect of heat on metal carbonates (silver, gold)
decomposes to form the metal, co2, o2
