REACTIONS OF METALS Flashcards
1
Q
magnesium reaction with water
A
very slow with water but reacts with steam
2
Q
calcium reaction with water
A
reacts steadily with cold water
3
Q
strontium/barium reaction with water
A
reacts vigorously with cold water
4
Q
what does metals reacting with cold water produce
A
hydroxides
5
Q
what does metals reacting with steam form
A
oxides
6
Q
extraction of titanium
A
TI reacts with carbon to form titanium carbide so a reactive metal is used to extract it
7
Q
why is an argon atmosphere used wen extracting titanium
A
so that magnesium doesn’t react with oxygen
8
Q
flue gas desulfurisation
A
coal and crude oil burn to produce SO2
dissolves in moisture causing acid rain
SO2 removed from power station chimneys by reacting with calcium oxide (alkali)
CaO + SO2 —> CaSO3
