Displacement is when a metal 'steals' oxygen from the other metal because it is more reactive. 4 of 13 Metal oxide + acid > Salt + water 5 of 13 Metal + acid > Salt + hydrogen 6 of 13 Metal + water Metal hydroxide + hydrogen 7 of 13 Metal carbonate + acid Salt + water + carbon dioxide 8 of 13 Hydrogen with lit splint observation Squeaky pop 9 of 13 Oxygen with splint observation Re lights a splint 10 of 13 Carbon dioxide splint observation Splint goes out 11 of 13 Carbon dioxide mixed with limewater observation Cloudy white 12 of 13 CuSo Copper Sulphate 13 of 13
