Pb
H
Cu
Ag
Au
Pt
what is reactivity determined by?
how easily they lose electrons
how are metals more reactive than carbon extracted?
electrolysis
how are metals less reactive than carbon extracted?
carbon reduction
which metals react with oxygen?
Cu and above
which metals react with water?
Mg and above
which metals react with acids
Pb and above
acid + metal
salt + hydrogen
what is the speed of reaction indicated by?
the rate at which hydrogen bubbles are given off
metal + water
metal hydroxide + hydrogen
oxidation (in terms of oxygen)
gain of oxygen
reduction (in terms of oxygen)
loss of oxygen
oxidation and reduction: formation of metal ore, extraction of metal
extraction of metal-R
formation of ore-O
metal + oxygen
metal oxide
